% \section{Introduction}
%
% The \packname{eurofont} package was written to do two complementary
% jobs: firstly, to automate the process of using a euro symbol from any
% source in any fount\footnote{I am one of the last people in the world
% to use this spelling of the word to refer to `a set of type in one
% size and style'.}; secondly, to generate a `faked' euro symbol from a C
% with two lines across it, which can be used automatically when no
% suitable real euro symbol exists.
%
% Despite the name, the \packname{eurofont} package does not itself
% have a fount containing euro symbols: it's meant to help you use
% founts with euro symbols.
%
% The \packname{eurofont} package defines two commands meant to be used
% in documents: the \comname{euro} command which prints a euro symbol,
% and the \comname[amount]{euros} command which prints a euro symbol
% next to its argument -- normally a number -- with a small space in
% between the two. The particular euro symbol printed depends on the way
% \packname{eurofont} has been set up: the decision made is based on the
% fount in use at the time you use the command. The \comname{euros}
% command uses the \comname{euro} command to print the euro symbol, so
% these commands print the same symbol under the same circumstances.
%
% There are several ways of controlling which particular euro symbol you
% get with any given fount; the idea is that -- with a bit of luck --
% most users won't need to do anything more complicated than passing
% options to \packname{eurofont} and making minor changes to the
% configuration file, \filename{eurofont.cfg}.
%
% Note for \OzTeX\ users (and perhaps others): throughout this document,
% I refer to the standard set of \PS Type 1 founts (Times, Helvetica,
% Courier, etc). If, like me, you use TrueType versions of Times,
% Palatino, etc., instead of \PS Type 1 versions, the difference doesn't
% matter.
%
% This is the second public release of the \packname{eurofont} package;
% as I had expected, at least one bug did escape my notice in the first
% release (it was a problem with the advice given on configuring dvips).
% I've fixed the problem reported, but there's probably a few more bugs
% lurking in the package; if you do spot any bugs, have any trouble with
% the documentation, you'd like to tell me how to configure the
% \dvidriver \emph{you} use (I'd love to hear from Amiga or Archimedes
% \TeX\ users in particular), or you'd just like to make a comment or
% suggestion about the \packname{eurofont} package, I'd appreciate an
% email at: |rebecca@astrid.u-net.com|.
%
% \subsection{What else do I need?}
%
% The only thing you must have to use the \packname{eurofont} package is
% a working \LaTeX2e\ installation. This package has only been tested
% with the June 1998 release of \LaTeX2e, but will probably work
% correctly with earlier versions. \packname{Eurofont} will not work
% with \LaTeX~2.09.
%
% The \packname{eurofont} package can be configured to produce useful
% euro symbols in the absence of any founts containing real euro
% symbols, but you will need to edit the configuration file if you want
% this; an introduction to configuring this package can be found in
% section~\vref{sec:config_intro}.
%
% In its default configuration, \packname{eurofont} expects to find
% Adobe's Eurofonts installed. If you want to avoid these, you can pass
% the \optname{marvosym} option to \packname{eurofont} and it'll expect
% the Marvosym fount instead. Adobe's Eurofonts have italic, bold, and
% bold italic variants which Marvosym lacks.
%
% Both Marvosym and the Eurofonts are \PS Type 1 founts: you can use
% them if you have a \PS printer, ATM (Adobe Type Manager), or a \PS
% emulator like Ghostscript. Section~\vref{sec:getPSfounts} has more on
% these founts and how to get them.
%
% The \packname{eurosym} and \packname{China2e} packages both have euro
% symbols in Metafont format which can be used by \packname{eurofont}.
% You'll get \packname{eurosym}'s euro symbol if you pass the
% \optname{eurosym} option to \packname{eurofont} -- this gives you
% \packname{eurosym}'s euro symbol instead of Adobe's Eurofonts or
% Marvosym's euro symbols, and also replaces the euro symbols you get
% with the Computer Modern founts. You will need to edit the
% configuration file if you want to use the euro symbol from the China2e
% fount.
%
%
% \subsection{How to install the package -- in brief}
%
% \begin{enumerate}
% \item Run \LaTeX\ on \filename{eurofont.ins}.
% \item Put \filename{eurofont.sty}, \filename{eurofont.cfg}, and all
% the files ending in \filename{.fd} into a directory on your
% tex-inputs search path.
% \item (optional) Get and install Adobe's Eurofonts, and/or the
% marvosym fount, and/or the \packname{China2e} package, and/or the EC
% founts (the T1 encoded re-working of the original Computer Modern
% founts), and/or the \packname{Eurosym} package. See
% section~\vref{sec:getfounts} for details.
% \item (optional) If you want to use Adobe's Eurofont's, put the
% \filename{zpeu...tfm} files into a directory on your tex-fonts search
% path, and the \filename{zpeu...vf} files into a directory on your vf
% (virtual founts) search path.
% \item (optional) If you intend to use the marvosym fount, put one
% of the two files \filename{fmvri8x.tfm} into a directory on your
% tex-fonts search path; put it with the file \filename{fmvr8x.tfm} that
% comes with the \packname{marvosym} distribution.
% \item (optional) Copy the appropriate lines from
% \filename{dvidrive.txt} to the appropriate file on your system to
% configure your \dvidriver to use marvosym and/or Adobe's Eurofonts.
% This procedure is also covered in section~\vref{sec:dvidriver_config}.
% \item (optional) Modify the file \filename{eurofont.cfg} as you like.
% \end{enumerate}
%
% \subsection{How to use the package -- a brief introduction}
%
% This is how to use \packname{eurofont} in your document:
%\begin{verbatim}
% \documentclass[a4paper]{article}
% \usepackage{eurofont}
% \begin{document}
% The euro symbol looks like this: \euro. A sum of money can
% be written like this: \euros{500}.
% \end{document}
%\end{verbatim}
% The \comname{euro} command prints the euro symbol; the \comname{euros}
% command is meant to be used to typeset a sum of money in euros: it
% prints the euro symbol to the left (by default) of its argument, with
% a small amount of space between the symbol and the text of the
% argument. If you give the \packname{eurofont} package the
% \optname{right} option, the euro symbol will be on the right.
%
% The \packname{eurofont} package's default setup assumes that you've
% got Adobe's Eurofonts installed. If you want use to euro symbols from
% the Marvosym fount instead, use the \optname{marvosym} option:
%\begin{verbatim}
% \usepackage[marvosym]{eurofont}
%\end{verbatim}
%
% The next question is: what do you get when you use the \comname{euro}
% or \comname{euros} command? The \packname{eurofont} package decides
% which euro symbol to use depending on the fount in use at the place
% where the \comname{euro} command is encountered. The way the package
% is set up initially, you get this:
% \begin{itemize}
% \item All bar one of the `standard' set of \PS founts get a
% euro symbol from one of Adobe's Eurofonts: Bookman, Times, Palatino, New
% Century Schoolbook, and Utopia use Euroserif; Avant Garde, Helvetica,
% Symbol, and Zapf Dingbats use Eurosans; and Courier uses Euromono.
% \item Zapf Chancery (the one exception) uses a euro symbol faked with
% medium rules.
% \item Each of the three Computer Modern text fount families (Computer
% Modern Roman, Computer Modern Sanserif, and Computer Modern
% Typewriter (\lfntname{cmr}, \lfntname{cmss}, and \lfntname{cmtt}) uses
% either the appropriate euro symbol from the matching `text companion' (TC)
% fount (if installed); or, if the TC founts appear to be missing,
% \packname{eurofont} will print a faked euro symbol instead.
% \item Everything else gets a euro symbol faked with medium weight
% rules.
% \end{itemize}
% The \optname{marvosym} option tells \packname{eurofont} to use the
% Marvosym fount's euro symbols in place of Adobe's Eurofonts.
%
% The faked euro symbols I refer to above are euro symbols produced by
% superimposing a pair of horizontal lines over a letter `C'. The
% result can be surprisingly tolerable in some cases.
%
% \subsubsection{Options}
%
% This is my best guess at the options most new users are likely to
% want to know about first, not a full list of all the options -- you
% can find that in section~\vref{sec:all_options}.
% \begin{description}
% \item[\optname{left}] This option makes the \comname{euros} command
% print the euro symbol to the left of its argument, which is normally a
% number; the \comname{euros} command is meant for typesetting sums of
% money. This is the default behaviour.
%
% \item[\optname{right}] This option makes the \comname{euros} command
% print the euro symbol to the right of its argument, which is normally
% a number; the \comname{euros} command is meant for typesetting sums of
% money.
%
% \item[\optname{marvosym}] This option tells \packname{eurofont} to use
% the Marvosym fount's euro symbols for the standard set of \PS
% Type 1 founts. The \packname{eurofont} package automatically fakes a
% bold version when needed, and you'll also get a decent faked
% italic/slanted version if your \dvidriver can slant a fount.
%
% \item[\optname{eurosym}] This option tells \packname{eurofont} to use
% the \packname{eurosym} package's euro symbol for the Computer Modern
% families and for the standard set of \PS Type 1 founts. If the
% \packname{eurosym} package isn't available, \packname{eurofont}
% complains and all euro symbols are created using the normal
% \packname{eurofont} code for printing faked euro symbols.
% \end{description}
%
% \subsection{Some founts with euro symbols}\label{sec:someeurofounts}
%
% It's a good idea to get some founts containing the euro symbol.
% Section~\vref{sec:getfounts} has more details of some freely available
% founts. In brief, the founts with euro symbols in that I know about are:
% \begin{center}
% \begin{tabularx}{\textwidth}{@{}ll>{\raggedright\arraybackslash}X@{}}
% \textbf{Fount} & \textbf{Format} & \textbf{Notes} \\[1ex]
% Adobe Eurofonts & PS Type 1 & Seriffed, sanserif, and
% monospaced all in upright,
% italic, bold, and bold italic\\
% Marvosym & pfa and pfb only & Seriffed, sanserif, and monospaced
% in upright medium only\\[0.5ex]
% China2e & Metafont & A single beautiful upright euro
% symbol \\[0.5ex]
% Eurosym & Metafont & The official euro and an
% alternative approach to printing a
% faked euro\\[0.5ex]
% Text Companion & Metafont & Founts containing extra
% symbols that come with the T1
% encoded version of the Computer
% Modern founts \\
% \end{tabularx}
% \end{center}
% If you know of other founts containing euro symbols that are used
% with \LaTeX\, do please let me know and I'll add them to this list.
%
% The \packname{china2e} and \packname{marvosym} packages come with
% founts in one shape and weight only: medium upright. Despite this, the
% \packname{eurofont} package will print what looks like a bold euro symbol
% from either fount, and can (with a bit of help from your \dvidriver)
% also manage italic and bold italic euro symbols from \packname{marvosym}.
%
% The way it works is this: \packname{eurofont} comes with two
% \filename{tfm} files -- both called \filename{fmvri8x.tfm} -- for a
% slanted version of the Marvosym fount\footnote{Use the \filename{tfm}
% file from the \filename{original} directory if you're using the
% original version of Marvosym (the \filename{pfa} or \filename{pfb}
% files from CTAN or the TrueType version from Martin Vogel's Web site);
% and use the \filename{tfm} file from the \filename{yandy} folder if
% you're using the Y\&Y version of Marvosym -- either downloaded from
% the Y\&Y Web site, or the Macintosh version from CTAN.}. This fount
% doesn't really exist, but some \dvidriver{}s can create a slanted
% fount from an upright one by leaning it to one side.
%
% Assuming your \dvidriver can create a slanted fount (dvips can -- see
% section~\ref{sec:dvidriver_config:mvs} for more details), this extra
% \filename{tfm} file means you can use the Marvosym fount's euro
% symbols with slanted or italic founts: the results you get with this
% should be good enough for all practical purposes. \packname{Eurofont}
% also has two commands to print a `poor man's bold' version of a euro
% symbol; one of these is used automatically to print bold versions of
% the Marvosym or China2e euro symbols, which are missing bold variants.
% These poor man's bold commands print six copies of the requested
% symbol, each offset from the others by a very small amount in a
% hexagonal arrangement. There's a bit more detail in
% section~\vref{sec:howitworks:EFpmb}.
%
% If you want to use the euro symbol from China2e, you could do worse
% than to read section~\vref{sec:config_intro}.
%
% \subsection{How to change what you get -- a brief
% intro}\label{sec:config_intro}
%
% The \packname{eurofont} package comes with a configuration file called
% \filename{eurofont.cfg}. The idea is that you can change this file as
% much as you like to meet your preferences.
%
% But before diving in and changing anything, there are several options
% that can change what the package does. There's a brief description of
% some of them in section~\vref{sec:someeurofounts}, and
% section~\vref{sec:all_options} tells all.
%
% The basic idea behind \packname{eurofont}'s \comname{euro} command is
% this: there are several lists which have their contents defined in the
% file \filename{eurofont.cfg}. When you use the \comname{euro} or
% \comname{euros} command, the current fount family is checked against
% each list in turn. If the fount family matches an entry in a list,
% then the command corresponding to that list is executed. This command
% prints a particular euro symbol. The first match you get decides which
% euro symbol you get: you can't get two euro symbols if one fount
% family is listed in, say, the \comname{chinaelist} and the
% \comname{seriflist}
%
% So, for example, the fount family \lfntname{ptm} (Adobe Times) is
% listed in \comname{seriflist}. If you use the \comname{euro} command
% in the middle of some text typeset in Times, the command
% \comname{makeserifeuro} is executed, and you get a euro symbol from
% Adobe's Euroserif fount (by default, that is; if you've used the
% \optname{marvosym} option, you'll get Marvosym's seriffed euro
% symbol). I'll explain how to find out the internal fount family name
% of each fount in a bit.
%
% The configuration file (\filename{eurofont.cfg}) contains this by
% default:
%\begin{verbatim}
%%
%% List contents Corresponding command
%%
% \EFaddtolist{\userlist}{}% \makeusereuro
% \EFaddtolist{\texteurolist}{}% \maketexteuro
% \EFaddtolist{\chinaelist}{}% \makechinaeeuro
% \EFaddtolist{\cmlist}{cmr,cmss,cmtt}% \makecmeuro
% \EFaddtolist{\seriflist}{pbk,pnc,ppl,ptm,put}% \makeserifeuro
% \EFaddtolist{\sanslist}{pag,phv,psy,pzd}% \makesanseuro
% \EFaddtolist{\monolist}{pcr}% \makemonoeuro
% \EFaddtolist{\fakemediumlist}{pzc}% \makefakemediumeuro
% \EFaddtolist{\fakelightlist}{}% \makefakelighteuro
% \EFaddtolist{\fakeheavylist}{}% \makefakeheavyeuro
%\end{verbatim}
% The lists are created at the start of the \packname{eurofont}
% package with nothing in them: the code above tells you
% the full story about what's in each list. You can use the
% \comname{EFaddtolist} command anywhere after the \packname{eurofont}
% package has been loaded; you can use it in individual document
% preambles if you like, as well as in \filename{eurofont.cfg}.
%
% Each fount in \LaTeX\ belongs to a fount family. For example, Bookman
% Roman, Bookman Italic, Bookman Bold, and Bookman Bold Italic are all
% different founts, but they belong to the Bookman family. This family
% has an internal \LaTeX\ name: \lfntname{pbk}. One way of discovering
% the name of a fount family is to use \packname{eurofont}'s
% \comname{showfontfamily} command in your document: it displays the
% internal name of the current fount family on the screen and in the log
% file.
%
% Before going any further, remember this: each list is a list of fount
% family names. If you're using a fount family that's in a particular
% list, you get the euro symbol generated by the command corresponding
% to that list. Section~\vref{sec:fountfamilies} has more notes on
% \LaTeX\ fount families.
%
% If, for example, you don't like the euro symbol that you get with
% Computer Modern Roman, and you'd rather have the euro symbol from
% China2e with Computer Modern Roman, you can do this by changing two lines.
% Where the configuration file says this:
%\begin{verbatim}
% \EFaddtolist{\chinaelist}{}
% \EFaddtolist{\cmlist}{cmr,cmss,cmtt}
%\end{verbatim}
% you should change it to this:
%\begin{verbatim}
% \EFaddtolist{\chinaelist}{cmr}
% \EFaddtolist{\cmrlist}{cmss,cmtt}
%\end{verbatim}
%
% You might have a new \PS fount that you'd like to use Adobe's
% Euroserif euro symbol with. If that fount is, say, Monotype Joanna
% (fount family name \lfntname{mjo}), you can do this by adding
% \lfntname{mjo} to the \comname{seriflist}:
%\begin{verbatim}
% \EFaddtolist{\seriflist}{pbk,pnc,ppl,ptm,put,mjo}
%\end{verbatim}
%
% Or you might be using (say) Bitstream Bernhard Modern (family name
% \lfntname{bb7}) which you might think doesn't go well with any of the
% real euro symbols on offer. You might prefer a euro symbol faked with
% light rules in this case. You can get this by saying:
%\begin{verbatim}
% \EFaddtolist{\fakelightlist}{bb7}
%\end{verbatim}
%
% Then again, you might have a fount that has a real euro symbol in it:
% call it Adobe Xyzzy (\lfntname{pxy}) for the sake of argument. If this
% fount has been set up properly for use with \LaTeX, the euro symbol
% will be available using the \comname{texteuro} command. Rather than
% having to use a different command to select the euro symbol if you're
% using this fount family, you can say:
%\begin{verbatim}
% \EFaddtolist{\texteurolist}{pxy}
%\end{verbatim}
%
% There are mechanisms that allow you to bypass the standard behaviours.
% You can, for example, use \comname{newcommand} in the configuration
% file to define any of the \comname{make...euro} commands to anything
% you like. You could, for example, say:
%\begin{verbatim}
% \newcommand{\makesanseuro}
% {{\fontfamily{phv}\selectfont\makefakeeuro}}
%\end{verbatim}
% and all fount families in the \comname{sanseurolist} would have a euro
% symbol faked from a C in Helvetica with two rules drawn across it.
%
% Alternatively, you could put a fount in \comname{usereurolist}, and
% you'd get a euro symbol generated by the \comname{makeusereuro}
% command. This is meant to be defined by you: by default, it prints a
% euro symbol faked with medium weight rules and displays on the screen a
% message explaining that you should have defined the
% \comname{makeusereuro} command to do what you want it to do. For
% example, the following lines in the configuration file:
%\begin{verbatim}
% \newcommand{\makeusereuro}
% {EUR}
%\end{verbatim}
% will give you `EUR' -- the standard international currency
% abbreviation for the euro currency unit -- for the euro symbol in all
% fount families listed in the \comname{usereurolist}.
%
% \comname{usereurolist} is the first list looked at: if a fount
% family is listed in the \comname{usereurolist} as well as another
% list, what you get is the euro symbol produced by
% \comname{makeusereuro}.
%
% Immediately after \comname{usereurolist} is examined, the
% \comname{euro} command looks to see if a command of the form
% \comname{<fam>euro} exists (where |<fam>| is the name of the
% current fount family). If it does, this command is executed and the
% \comname{euro} command finishes. For example, assume you've designed a
% euro symbol to match URW's Arnold Boecklin fount (family name
% \lfntname{uab}). Let's say you've written a command
% \comname{arnoldboecklineuro} to print this symbol. You could say this:
%\begin{verbatim}
% \newcommand{\uabeuro}{\arnoldboecklineuro}
%\end{verbatim}
% and the \comname{euro} command would print your new euro symbol
% whenever you were using Arnold Boecklin.
%
% \subsection{About this package and document}
%
% The original aim of the \packname{eurofont} package was to provide a
% trivial interface to allow one to use the euro symbols from Adobe's
% Eurofonts with any fount. The package has grown a bit since the
% original idea, which might explain a few things. While their
% contributions to the final code might look small, this package
% couldn't have been started (let alone finished) without the help of
% Donald Arseneau and Stefan Ulrich (in alphabetical order, in case
% you're wondering). They provided the list handling code which is at
% the heart of the package.
%
% The biggest problem I had with this package was documenting it. I've
% no idea whether or not the documentation has `hit the right note' --
% if you've any comments at all to make about the documentation (or the
% package for that matter), do please email me and let me know what you
% think. Comments, suggestions, and bug reports are all very much
% welcome. To say that writing the documentation was a headache is
% putting it mildly. If you read the documentation from start to
% finish, you'll notice that there's a certain amount of repetition.
% This is deliberate, and is meant to make it easier to use the
% documentation.
%
% One problem that this package will face is that more and more founts
% containing euro symbols will appear as time goes on. With a bit of
% luck, it's flexible enough for you to be able to configure it to deal
% with these new founts. If not, or if you've had a thought about what
% might be done with one or more of these new founts, do please let me
% know by email -- if it's practical, it would be nice to modify this
% package to make it more useful.
%
% \section{Installing the \packname{eurofont} package}
% \label{sec:installation}
%
% The \packname{eurofont} package proper comes in two files:
% \filename{eurofont.dtx} and \filename{eurofont.ins}. Running
% \LaTeX\ on \filename{eurofont.dtx} produces this document, so I'll
% assume you've done that. Running \LaTeX\ on \filename{eurofont.ins}
% generates:
% \begin{center}
% \begin{tabularx}{\textwidth}{@{}l>{\raggedright\arraybackslash}X@{}}
% \filename{dvidrive.txt}& Information on configuring \dvidriver{}s to
% use Adobe's Eurofonts and the Marvosym fount. \\
% \filename{eurofont.cfg}& The configuration file: edit this file to change
% \packname{eurofont}'s behaviour. \\
% \filename{eurofont.sty}& The package file proper. \\
% \filename{uzmvs.fd} & \LaTeX\ code for selecting the Marvosym fount. \\
% \filename{uzpeur.fd} & \LaTeX\ code for selecting Adobe's Euroserif fount.\\
% \filename{uzpeuss.fd} & \LaTeX\ code for selecting Adobe's Eurosans fount.\\
% \filename{uzpeutt.fd} & \LaTeX\ code for selecting Adobe's Euromono fount.\\
% \end{tabularx}
% \end{center}
% \filename{eurofont.cfg} and \filename{eurofont.sty} should be put in
% a directory on your tex-inputs search path: they're both essential.
% If you're using either Adobe's Eurofonts or the Marvosym fount, read
% \filename{dvidrive.txt}. Once you've used it, you can discard it.
%
% The \filename{fd} files are only needed if you're using the founts in
% question. What they're for is this: \TeX\ can only typeset text in a
% particular fount if it has a \filename{tfm} file corresponding to that
% fount to look at. \LaTeX\ \filename{fd} files contain code to select a
% \filename{tfm} file when you ask for a particular fount using \LaTeX\
% commands. For example, you might ask for `U encoded Adobe Euroserif in
% bold italic'. \LaTeX\ would then look at the file
% \filename{uzpeur.fd}, and discover that this request corresponded to
% \filename{zpeubi.tfm}.
%
% If you intend to use the Marvosym fount, put the file
% \filename{uzmvs.fd} into a directory on your tex-inputs search path.
% This file is named so that it won't clash with the original Marvosym
% fount definitions: you don't have to worry about the
% \packname{marvosym} package getting confused because the
% \packname{eurofont} package uses the \packname{marvosym} fount
% differently.
%
% If you intend to use Adobe's Eurofonts, put the three
% \filename{uzpeu...fd} files into a directory on your tex-inputs search
% path. If you already have files with these names from a different
% source, I suggest that you replace the older files with the
% \filename{fd} files that come with \packname{eurofont}. If this causes
% any problems, please let me know by emailing
% \texttt{rebecca@astrid.u-net.com}.
%
% \subsection{Using Marvosym and Adobe's Eurofonts}
%
% How to get these founts is covered in section~\vref{sec:getfounts}. To
% use them with the \packname{eurofont} package, you need to install the
% appropriate \filename{fd} files and configure your \dvidriver, as
% explained above. Assuming you have installed the actual fount files on
% your computer, you then need \filename{tfm} files for these founts:
% these are the files that tells \TeX\ exactly what size each letter is,
% and allows it to produce output with a given fount.
%
% The \packname{eurofont} package comes with suitable \filename{tfm}
% files for Adobe's Eurofonts, and two extra \filename{tfm} files for
% the Marvosym fount. Which of these two \filename{tfm} files you should
% use depends on which version of the Marvosym fount you have.
%
% \subsubsection{Using Adobe's Eurofonts}
%
% If you intend to use Adobe's Eurofonts, you should put all 12 files in
% the \filename{adobeuro/tfmfiles/} directory into a tex-fonts
% directory. These files should exist happily alongside any other
% \filename{tfm} files generated for Adobe's Eurofonts: being generated
% by \packname{afm2tfm}, they should be identical to any others you
% might have. I suggest that you remove any other \filename{tfm} files
% you might have for these founts unless you know that you need to keep
% them installed. If this advice causes you any problems, please email
% me and let me know.
%
% \subsubsection{Using the Marvosym fount}
%
% The Marvosym fount comes with a \filename{tfm} file of its own, and
% the \packname{eurofont} package includes two extra \filename{tfm}
% files: you should use one of these to allow you access to a faked
% italic/slanted version of Marvosym, assuming that your \dvidriver can
% produce a faked italic by slanting an upright fount. Both dvips and
% \OzTeX\ can do this.
%
% If you are using a version of the original Marvosym fount (the
% original \filename{pfa} or \filename{pfb} files from CTAN, or the
% Truetype version from Martin Vogel's Web site), then you should take
% the file \filename{fmvri8x.tfm} from the directory
% \filename{marvosym/tfmfiles/original}, and put it in the same
% tex-fonts directory as the file \filename{fmvr8x.tfm} which came with
% the \packname{marvosym} package.
%
% If you are using one of the ATM-compatible versions of the Marvosym
% fount from Y\&Y (either from Y\&Y's Web site or any of the Mac
% versions from CTAN), things are slightly more complicated. In this
% case, you might be using the Y\&Y supplied \filename{tfm} file
% \filename{marvosym.tfm} to use this fount. If so, leave
% \filename{marvosym.tfm} alone: take the files \filename{fmvr8x.tfm}
% and \filename{fmvri8x.tfm} from the directory
% \filename{marvosym/tfmfiles/yandy}, and put them in the tex-fonts
% directory which contains \filename{marvosym.tfm}. If you have changed
% the name of the Y\&Y supplied \filename{tfm} file to
% \filename{fmvr8x.tfm}, just add \filename{fmvri8x.tfm}.
%
% Note that you should not use the file \filename{fmvr8x.tfm} supplied
% for the original Marvosym fount with any of the Y\&Y versions of
% Marvosym, or vice versa: the founts are very, very similar, but differ
% in tiny details which affect the metrics file very slightly. You
% should therefore use the \filename{tfm} file supplied with the
% particular fount you're using. If you're not sure of the source of the
% Marvosym \filename{tfm} file already installed on your computer, you
% might prefer to replace it with the appropriate version of
% \filename{fmvr8x.tfm} supplied with the \packname{eurofont} package.
%
% The original \PS version of the Marvosym fount has the \PS name
% \texttt{Martin\_Vogels\_Symbole}, while the Y\&Y re-worked version has
% the \PS name \texttt{Marvosym}; this leads to different \dvidriver
% configuration file entries which should help you avoid any confusion
% over which version you've got.
%
% \section{All the options}\label{sec:all_options}
%
% Here are all of \packname{eurofont}'s options, presented in no
% particular order.
% \begin{description}
% \item[\optname{left}] This option makes the \comname{euros} command
% print the euro symbol to the left of its argument. When you use this
% option, it's also passed to the \packname{eurosym} package, so that
% \packname{eurosym}'s \comname{EUR} command will also print the euro
% symbol to the left of its argument. This is the default behaviour.
%
% \item[\optname{right}] This option makes the \comname{euros} command
% print the euro symbol to the right of its argument. When you use this
% option, it's also passed to the \packname{eurosym} package, so that
% \packname{eurosym}'s \comname{EUR} command will also print the euro
% symbol to the right of its argument.
%
% \item[\optname{marvosym}] This option tells \packname{eurofont} to use
% the Marvosym fount's euro symbols for the standard set of \PS
% Type 1 founts. The \packname{eurofont} package automatically fakes a
% bold version when needed, and you'll also get a decent faked
% italic/slanted version if your \dvidriver can slant a fount. This
% option counteracts the \optname{adobeeurofonts} option, and can be
% over-ridden by the \optname{eurosym} option.
%
% \item[\optname{adobeeurofonts}] This option tells \packname{eurofont}
% to use Adobe's Eurofonts to supply the euro symbols for the standard
% set of \PS Type 1 founts; this setting is used by default. This
% option counteracts the \optname{marvosym} option, and can be
% over-ridden by the \optname{eurosym} option.
%
% \item[\optname{eurosym}] This option tells \packname{eurofont} to use
% the \packname{eurosym} package's euro symbol for the Computer Modern
% families, and the standard set of \PS Type 1 founts. If the
% \packname{eurosym} package isn't available, \packname{eurofont}
% complains and all euro symbols are created using the normal
% \packname{eurofont} code for printing faked euro symbols.
%
% \item[\optname{noeurosym}] This option counteracts the
% \optname{eurosym} option; if (for example) you have a configuration
% file that says \comname{ExecuteOptions\ttlb eurosym\ttrb}, you can tell
% \packname{eurofont} \emph{not} to use \packname{eurosym}'s euro
% symbols, and use the normal founts -- typically Adobe's Eurofonts and
% the Text Companion founts. This is the default behaviour.
% \end{description}
%
% These next four options only affect what you get when you've given the
% \packname{eurofont} package the \optname{eurosym} option. See the
% \packname{eurosym} package's documentation for more details.
% \begin{description}
% \item[\optname{official}]This option is passed to the
% \packname{eurosym} package, and tells it to give you the official euro
% symbol.
%
% \item[\optname{gen}]This option is passed to the \packname{eurosym}
% package, and tells it to give you a faked euro symbol.
%
% \item[\optname{gennarrow}] This option is passed to the
% \packname{eurosym} package, and tells it to give you a faked euro
% symbol with narrow cross-strokes.
%
% \item[\optname{genwide}]This option is passed to the
% \packname{eurosym} package, and tells it to give you a faked euro
% symbol with wide cross-strokes.
% \end{description}
%
% The following three options affect how \packname{eurofont} produces
% faked euro symbols.
% \begin{description}
% \item[\optname{noslantfakeeuro}] \packname{Eurofont}'s faked euro
% symbols are produced with two rules of the same length.
%
% \item[\optname{normalslantfakeeuro}] \packname{Eurofont}'s faked euro
% symbols are produced with two rules of slightly different length: the
% lower rule is the shorter of the two. This is the default
% behaviour; it approximates the difference in length of the two rules
% in the official euro symbol.
%
% \item[\optname{bigslantfakeeuro}] \packname{Eurofont}'s faked euro
% symbols are produced with two rules of greatly different length: the
% lower rule is by far the shorter of the two. This was inspired by
% the China2e fount's euro symbol.
% \end{description}
%
% And finally, some options which don't seem to belong with anything
% else.
% \begin{description}
% \item[\optname{notextcomp}] This option tells the \packname{eurofont}
% package not to load the \packname{textcomp} package; it counteracts
% the \optname{textcomp} option. You might want to use this option if
% you find that some characters or accents are unexpectedly wrong when
% using the \packname{eurofont} package -- this sort of thing can be
% caused by loading the \packname{textcomp} package. See also the
% \optname{fixtieaccent} option.
%
% \item[\optname{textcomp}] This option tells the \packname{eurofont}
% package to load the \packname{textcomp} package (part of the standard
% \LaTeX\ distribution) if it is available. This package defines the
% \comname{texteuro} command (amongst other things). Trying to load
% \packname{textcomp} is the default behaviour. One possibly unwanted
% effect of loading \packname{textcomp} is that tie accents are
% typically messed up if you're using \PS Type 1 founts; the
% \optname{fixtieaccent} option can help out with this.
%
% \item[\optname{fixtieaccent}] This option counteracts the
% \optname{nofixtieaccent} option: it makes \packname{eurofont} define
% the tie accent to work the way it does as standard when the
% \packname{textcomp} package hasn't been loaded. If you find tie
% accents no longer work when using \packname{eurofont}, you can use
% either this option or the \optname{notextcomp} option to fix things.
%
% \item[\optname{nofixtieaccent}] This option counteracts the
% \optname{fixtieaccent} option: it stops \packname{eurofont} defining
% the tie accent to work the way it does as standard when the
% \packname{textcomp} package hasn't been loaded. This is the default
% behaviour.
%
% \item[\optname{debugreport}] This option tells the
% \packname{eurofont} package to print all sorts of debugging
% information out when you use its commands. I added this option for my
% own benefit, but you might find it useful if you're configuring
% \packname{eurofont} in strange fashions and not getting what you want.
%
% \item[\optname{nodebugreport}]This option tells the
% \packname{eurofont} package not to print out any debugging
% information. This is the default behaviour.
% \end{description}
%
% For those who might be interested: the following lines are executed
% just before loading the configuration file:
%{\small
%\begin{verbatim}
% \ExecuteOptions{adobeeurofonts}% Use Adobe's Eurofonts
% \ExecuteOptions{noeurosym}% Don't use eurosym
% \ExecuteOptions{left}% Euro symbol on left
% \ExecuteOptions{normalslantfakeeuro}% Fake euros with slight slant
% \ExecuteOptions{nodebugreport}% No debugging reports
% \ExecuteOptions{textcomp}% Load the textcomp package
% \ExecuteOptions{nofixtieaccent}% Don't modify tie accents
%\end{verbatim}
%}
% You can therefore over-ride any of these defaults by placing a
% subsequent \comname{ExecuteOptions} statement in the configuration
% file. For example, to make the \comname{euros} command place the
% euro symbol on the right of the sum by default, add:
%\begin{verbatim}
% \ExecuteOptions{right}
%\end{verbatim}
% to the configuration file, \filename{eurofont.cfg}.
%
% \section{Configuring the \packname{eurofont} package}\label{sec:config}
%
% There are three main mechanisms for changing the behaviour of
% \packname{eurofont}'s \comname{euro} command: passing an option to
% the \packname{eurofont} package, adding a fount family name to one
% of \packname{eurofont}'s lists, and re-defining the \comname{make...}
% commands used by the \comname{euro} command to print euro symbols.
% Options have been covered in section~\vref{sec:all_options}; the
% other two are covered here.
%
% The \packname{eurofont} package comes with a configuration file --
% \filename{eurofont.cfg} -- that's meant to be changed to match your
% preferences. If you want to add a fount family to a list, or re-define
% some commands, you can make the changes in the configuration file. You
% can also put code to do these jobs in a document file if you like.
% Please don't change \filename{eurofont.sty} itself, unless you change
% its name to something else.
%
% The way the \comname{euro} command works is this: when you use the
% \comname{euro} command, it compares the current fount family name with
% the contents of a series of lists. If the current fount family name is
% in a given list, the command corresponding to that list is executed.
% This prints a particular euro symbol, and the \comname{euro} command
% finishes. If you don't know what a fount family name is in \LaTeX,
% have a look at section~\vref{sec:fountfamilies}.
%
% The lists are created at the start of the \packname{eurofont} package,
% and have fount family names entered into them by the
% \comname{EFaddtolist} command. There's more than just the lists I've
% mentioned in section~\ref{sec:config_intro}, though. The configuration
% file contains the following lines by default:
%\begin{verbatim}
%%
%% List contents Corresponding command
%%
% \EFaddtolist{\userlist}{}% \makeusereuro
% \EFaddtolist{\texteurolist}{}% \maketexteuro
% \EFaddtolist{\chinaelist}{}% \makechinaeeuro
% \EFaddtolist{\cmlist}{cmr,cmss,cmtt}% \makecmeuro
% \EFaddtolist{\seriflist}{pbk,pnc,ppl,ptm,put}% \makeserifeuro
% \EFaddtolist{\sanslist}{pag,phv,psy,pzd}% \makesanseuro
% \EFaddtolist{\monolist}{pcr}% \makemonoeuro
% \EFaddtolist{\fakemediumlist}{pzc}% \makefakemediumeuro
% \EFaddtolist{\fakelightlist}{}% \makefakelighteuro
% \EFaddtolist{\fakeheavylist}{}% \makefakeheavyeuro
%
% \EFaddtolist{\faketexteurolist}{}
%
%% Put all the standard LaTeX weights (and likely extras)
%% into one of the following lists:
%
% \EFaddtolist{\EFlightserieslist}{ul,el,l,ulc,elc,lc,ulx,elx,lx}
% \EFaddtolist{\EFmediumserieslist}
% {m,mb,db,sb,mc,mbc,dbc,sbc,mx,mbx,dbx,sbx}
% \EFaddtolist{\EFboldserieslist}{b,bx,bc}
% \EFaddtolist{\EFultraboldserieslist}{eb,ub,ebc,ubc,ebx,ubx}
%\end{verbatim}
% The point of the configuration file is that you should change it any
% way you like. But what do all these lines mean? In brief, what goes on
% is this: when you use the \comname{euro} command (and remember that
% the \comname{euro} command is used by the \comname{euros} command so
% this discussion applies to both commands), the current \LaTeX\ fount
% family name is compared to the contents of each of the lists above, in
% the order given, with an extra test I'll mention in a bit. If, for
% example, you're using New Century Schoolbook (fount family name
% \lfntname{pnc}), what happens with the default settings is this:
% \begin{enumerate}
% \item \comname{userlist} is examined. It's empty, so no match is
% found, and the command continues.
% \item This is the extra test mentioned above: a test is made to see if
% the command \comname{pnceuro} exists (in general, the command
% \comname{<fam>euro} is looked for, where |<fam>| is the \LaTeX\ fount
% family name of the current fount). If this command exists, it's
% executed and the \comname{euro} command terminates. In this case, the
% command doesn't exist, so the command continues.
% \item \comname{texteurolist} is examined. It's empty, so the
% \comname{euro} command continues.
% \item \comname{chinaelist} is examined. It's empty, so the
% \comname{euro} command continues.
% \item \comname{cmlist} is examined. It's not empty: the current fount
% family is \lfntname{pnc}, but the list contains \lfntname{cmr},
% \lfntname{cmss}, and \lfntname{cmtt}. No match is found, so the
% \comname{euro} command continues.
% \item \comname{seriflist} is examined. It's not empty: the current
% fount family is \lfntname{pnc}, and the list contains \lfntname{pbk},
% \lfntname{pnc}, \lfntname{ppl}, \lfntname{ptm}, and \lfntname{put}. A
% match is found, so \comname{makeserifeuro} -- the command
% corresponding to this list -- is executed, which prints a euro symbol
% from one of Adobe's Euroserif founts, and the \comname{euro} command
% finishes.
% \end{enumerate}
% You might be wondering what the \comname{faketexteuro} list is for. If
% a fount family is listed in \comname{faketexteuro}, the
% \comname{maketexteuro} command will always execute the
% \comname{makefakeeuro} command to generate a faked euro symbol for
% that fount family. It prevents the \comname{euro} command from
% printing a euro symbol using the \comname{texteuro} command. I'm not
% sure that this is particularly useful, but it seemed like a good idea
% at the time.
%
% Another unanswered question is: what happens if the \comname{euro}
% command has made all its tests and not printed a euro symbol? In this
% case, the \comname{makedefaulteuro} command is executed. By default,
% this command executes the \comname{makefakeeuro} command which prints
% a euro symbol faked with medium weight rules. You can of course
% re-define the \comname{makedefaulteuro} and \comname{makefakeeuro}
% commands any way you like.
%
% The \comname{EF...serieslist} commands are used by the commands that
% print faked euro symbols; these commands are slightly more involved
% than you might think. I'll deal with this in detail in a bit.
%
% \subsection{The \comname{make...euro} commands}\label{sec:config-makeeuro}
%
% It might be that you want to do something that can't be done
% conveniently by just changing which fount families are listed in the
% lists above. If so, you'll probably find it most convenient to play
% around with the definitions of the various \comname{make...euro}
% commands; please do cut-and-paste the original definitions into the
% configuration file and modify them there if you think this will help.
% I used the \comname{providecommand} command to define all the
% \comname{make...euro} commands so that the definitions in
% \filename{eurofont.sty} won't have any effect if the commands have
% been defined earlier. There's more detail on what these commands do in
% section~\vref{sec:how_it_works} and in the commented source code.
%
% The \comname{euro} command works like this: the current fount family
% name is compared against the contents of a series of lists. If the
% current fount family is present in a particular list, the command
% corresponding to that list is executed. The first match ends the
% execution of the \comname{euro} command: you'll not get two euro
% symbols if the current fount family is in two lists. You can see what
% I mean in section~\vref{sec:how_euro_works}.
%
% One anomaly is the second test made in the \comname{euro} command,
% directly after looking in \comname{userlist}: this second test doesn't
% check for a match in a list, but instead checks for the existence of a
% command \comname{<fam>euro}, where |<fam>| is the current fount family
% name. If this command exists, it's executed and the \comname{euro}
% command ends. For example, if you define:
%\begin{verbatim}
% \newcommand{\pcreuro}{EUR}
%\end{verbatim}
% every time you use the \comname{euro} or \comname{euros} command while
% using Courier -- which has the fount family name \lfntname{pcr} --
% you'll get `EUR' printed (the standard international abbreviation for
% the euro) rather than a euro symbol of any sort.
%
% This table is a partial summary of what goes on:
% \begin{center}\small
% \begin{tabularx}{\textwidth}{@{}ll>{\raggedright\arraybackslash}X@{}}
% \textbf{List name} & \textbf{Command executed}
% & \textbf{What you get by default} \\[1ex]
% \comname{userlist} & \comname{makeusereuro}
% & Fakes a euro and prints a warning. \\
% & \comname{<fam>euro}
% & If it exists, \comname{<fam>euro} is
% executed. \\
% \comname{texteurolist } & \comname{maketexteuro}
% & Prints a euro symbol from the current
% fount or a faked euro symbol. \\
% \comname{chinaelist} & \comname{makechinaeeuro}
% & Prints the euro from the China2e fount. \\
% \comname{cmlist} & \comname{makecmeuro}
% & Prints a euro symbol from the current
% fount or a faked euro symbol. \\
% \comname{seriflist} & \comname{makeserifeuro}
% & Prints a euro from Adobe Euroserif. \\
% \comname{sanslist} & \comname{makesanseuro}
% & Prints a euro from Adobe Eurosans. \\
% \comname{monolist} & \comname{makemonoeuro}
% & Prints a euro from Adobe Euromono. \\
% \comname{fakelightlist} & \comname{makefakelighteuro}
% & Fakes a euro with light weight rules. \\
% \comname{fakemediumlist} & \comname{makefakemediumeuro}
% & Fakes a euro with medium weight rules. \\
% \comname{fakeheavylist} & \comname{makefakeheavyeuro}
% & Fakes a euro with heavy weight rules. \\
% \end{tabularx}
% \end{center}
% What happens when you use the \comname{euro} command is that each list
% is considered in turn, starting with the \comname{userlist}. If the
% fount family being used at that point in the document is in that list,
% a euro symbol is generated by the specified command and that's the end
% of the command. If the fount family being used isn't in the first
% list, the next list is looked at and so on. If this explanation is
% less than crystal clear, you might find it useful to read
% section~\vref{sec:how_euro_works}.
%
% If each list has been checked and the current fount family hasn't been
% found in any of them, the \comname{makedefaulteuro} command is
% executed. This produces a faked euro symbol: the \packname{eurofont} package
% has commands to make these by drawing two rules over a letter C; they
% can be surprisingly acceptable particularly if made with a sanserif
% fount.
%
% A brief description of what each of the \comname{make...euro} command
% does is:
%
% \begin{description}
% \item[\comname{makefakeeuro}] This command doesn't correspond to a
% list, but is used by the \comname{makedefaulteuro} command and other
% parts of the \packname{eurofont} package. What it does is this: it
% first checks to see if the command \comname{<fam>fakeeuro} exists,
% where |<fam>| is the current \LaTeX\ fount family name. If this
% command exists, it's executed; if not, the current fount family name
% is checked against (in this order) the \comname{fakelightlist},
% \comname{fakemediumlist}, and \comname{fakeheavylist}. If there's a
% match, it executes \comname{makefakelighteuro},
% \comname{makefakemediumeuro}, or \comname{makefakeheavyeuro}
% (depending on which list had the match). If it finds no match, it
% executes \comname{makefakemediumeuro}.
%
% The \comname{makefake...euro} commands produce euro symbols faked by
% placing a pair of rules over a letter `C'.
%
% For example, if you were using Zapf Chancery, which has an internal
% \LaTeX\ fount family name of \lfntname{pzc}, and
% \comname{makefakeeuro} were executed, the first test would be to see
% if \comname{pzcfakeeuro} existed. Since \packname{eurofont} does
% define this command, it exists, and is executed.
%
% \item[\comname{makeusereuro}] Meant to be defined by you; by default,
% this command generates an on-screen warning and executes the
% \comname{fakemediumrule\-euro} command which prints a euro symbol
% faked with medium rules.
%
% \item[\comname{maketexteuro}]\label{item:maketexteuro:config}
% This command executes the \comname{texteuro} command if these three
% conditions are met: the current \LaTeX\ fount family is not listed in
% the \comname{faketexteurolist}, the \comname{texteuro} command exists
% (it's defined by the \packname{textcomp} package which
% \packname{eurofont} tries to load by default), and the fount
% definition file |ts1<fam>.fd| exists (where |<fam>| is the current
% \LaTeX\ fount family name -- this \filename{fd} file will normally
% exist if the fount does have a euro symbol available). If these
% conditions are not met, it executes \comname{makefakeeuro} instead of
% \comname{texteuro}.
%
% The \comname{texteuro} command, defined by \packname{textcomp}, prints
% a euro symbol from the current fount, assuming everything's working
% right; the \comname{makefakeeuro} command prints a euro symbol faked
% by placing two rules over a letter `C'.
%
% \item[\comname{makechinaeeuro}] This command prints the euro symbol
% from the China2e fount. If the current fount series is listed as light
% or medium by being in either \comname{EFlightserieslist} or
% \comname{EFmediumserieslist} you'll get the straight China2e euro
% symbol; if the current fount series is listed as bold or ultra bold by
% being in either \comname{EFbold\-series\-list} or
% \comname{EFultraboldserieslist} you'll get a faked bold China2e euro
% symbol. If the current fount series isn't listed in any of these
% lists, you'll get a straight China2e euro symbol.
%
% The \comname{makechinaeeuro} command checks for the \packname{china2e}
% package: if it's missing, you'll get a warning message and a faked
% euro symbol.
%
% \item[\comname{makecmeuro}] This command normally has the same effect
% as \comname{maketexteuro}: it executes the \comname{texteuro} command
% if the three conditions are met (see above, in the
% \comname{maketexteuro} entry on
% page~\pageref{item:maketexteuro:config}); otherwise, it executes
% \comname{makefakeeuro} -- this command fakes a euro symbol from a C
% over-printed with two rules. This behaviour can be changed using an
% option: if you've passed the \packname{eurosym} option to
% \packname{eurofont}, the \comname{makecmeuro} command prints Eurosym's
% euro symbol instead.
%
% \item[\comname{makeserifeuro}]
% This command normally prints a euro symbol from one of Adobe's
% Euroserif founts (medium, italic, bold, or bold italic). If you've
% passed the \optname{marvosym} option to \packname{eurofont}, you'll
% get a seriffed euro symbol from the Marvosym fount instead. Since
% Marvosym doesn't have real bold euro symbols, you'll get a faked bold
% euro symbol if the current fount series is listed in
% \comname{EFboldserieslist} or \comname{EFultraboldserieslist} (as
% with the \comname{makechinaeeuro} command).
%
% If you've passed the \optname{eurosym} option to \packname{eurofont},
% you'll get a euro symbol generated by \packname{eurosym}'s
% \comname{euro} command: this option over-rides both the
% \optname{marvosym} option and the default \optname{adobeeurofonts}
% option.
%
% The commands \comname{makeserifeuro}, \comname{makesanseuro}, and
% \comname{makemonoeuro} are very similar.
%
% \item[\comname{makesanseuro}]
% This command normally prints a euro symbol from one of Adobe's
% Eurosans founts (medium, italic, bold, or bold italic). If you've
% passed the \optname{marvosym} option to \packname{eurofont}, you'll
% get a sanserif euro symbol from the Marvosym fount instead. Since
% Marvosym doesn't have real bold euro symbols, you'll get a faked bold
% euro symbol if the current fount series is listed in
% \comname{EFboldserieslist} or \comname{EFultraboldserieslist} (as
% with the \comname{makechinaeeuro} command).
%
% If you've passed the \optname{eurosym} option to \packname{eurofont},
% you'll get a euro symbol generated by \packname{eurosym}'s \comname{euro}
% command: this option over-rides both the \optname{marvosym} option and

% Marvosym doesn't have real bold euro symbols, you'll get a faked bold
% euro symbol if the current fount series is listed in
% \comname{EFboldserieslist} or \comname{EFultraboldserieslist} (as
% with the \comname{makechinaeeuro} command).
%

% the default \optname{adobeeurofonts} option.
%
% The commands \comname{makeserifeuro}, \comname{makesanseuro}, and
% \comname{makemonoeuro} are very similar.
%
% \item[\comname{makefakelighteuro}]
% First checks to see if the command \comname{<fam>fakeeuro} exists
% (where |<fam>| is the name of the current fount family); if so, it
% executes \comname{<fam>fakeeuro} (as with \comname{makefakeeuro}). If
% not, it executes \comname{fakelighteuro} -- this gives you a euro
% symbol faked with light rules.
%
% The particular weight (or thickness) of these rules varies depending
% on which \comname{EF...serieslist} the current fount series is in: the
% rules are lightest if the current fount series is listed in
% \comname{EFlightserieslist}, progressively heavier if listed in
% \comname{EFmediumseries} and \comname{EFboldseries}, and heaviest if
% listed in \comname{EFultraboldseries}. If the current fount series
% isn't listed in any of these lists, you get the rules you'd get if the

% \comname{makedefaulteuro} command prints a faked euro symbol generated
% with the \comname{makefakeeuro} command.
%
% For the curious: \packname{eurofont} defines the \comname{ESeuro}

% \section{Founts containing euro symbols}\label{sec:getfounts}
%
% This section was written in October 1998: I know that there are founts
% other than the ones I've noted below that contain euro symbols, but
% these are the only ones I know of that are convenient to use with
% \LaTeX. As far as I know, the founts currently included with `euro
% compatible' versions of MS-Windows and the MacOS have a euro symbol
% that is close to the official euro symbol. This doesn't match the
% fount it's included with in most cases. It seems to me that there is
% nothing to be gained by using these euro symbols with \LaTeX. I expect
% this situation will change in time, and matching euro symbols are
% designed for more founts.
%
% Aside from the Text Companion founts which accompany the EC founts
% (the relatively new T1 encoded versions of the standard Computer
% Modern founts used by \LaTeX -- I think they are included with all
% recent \LaTeX\ distributions), Metafont euro symbols are included in
% two other founts available from CTAN: China2e, which has a single very
% lovely euro symbol; and Eurosym, which has the official euro symbol.
% You can find out how to get all of these in
% section~\vref{sec:getMFfounts}.
%
% The euro symbols in the Text Companion founts were designed before
% the final official euro symbol was decided on, and might be considered
% a bit eccentric by some.
%
% I know of two sets of \PS Type 1 founts containing euro
% symbols: Adobe's Eurofonts, a set of 12 founts providing seriffed,
% sanserif, and monospaced euro symbols in medium upright, italic, bold,
% and bold italic version; and the Marvosym fount, which has three euro
% symbols, very similar to the medium upright seriffed, sanserif, and
% monospaced euro symbols from Adobe.
%
% Your \TeX\ system's documentation should tell you if you can use \PS
% Type 1 founts. Typically, you need either: a \PS printer or \PS
% interpreter on your computer such as Ghostscript; or Adobe Type
% Manager (ATM) installed on your computer and a \dvidriver (such as
% \OzTeX's) which can take advantage of this.
%
% \subsection{Getting Marvosym or Adobe's Eurofonts}\label{sec:getPSfounts}
%
% Adobe's Eurofonts are available (October 1998) in a Mac version
% from here:
%\begin{verbatim}
% ftp://ftp.adobe.com/pub/adobe/type/mac/all/eurofont.sea.hqx
% ftp://ftp-pac.adobe.com/pub/adobe/type/mac/all/eurofont.sea.hqx
%\end{verbatim}
% Textures users on Macs should also download these files from CTAN:
%\begin{verbatim}
% systems/mac/textures/contrib/IdealFonts/EuroDefs.sit.hqx
% systems/mac/textures/contrib/IdealFonts/README.IF
%\end{verbatim}
% You should still download Adobe's Eurofonts separately.
%
% Adobe's Eurofonts are available (October 1998) in a version suitable
% for MS-Windows PCs and Unix from here:
%\begin{verbatim}
% ftp://ftp.adobe.com/pub/adobe/type/win/all/eurofont.exe
% ftp://ftp-pac.adobe.com/pub/adobe/type/win/all/eurofont.exe
%\end{verbatim}
% These files are self-extracting archives on MS-Windows computers which
% can be decompressed on Unix computers with the \verb|unzip| command.
%
% The Marvosym fount is available from CTAN in \filename{pfb} and
% \filename{pfa} versions, and I gather these versions won't work with
% ATM. There are also Mac versions based on the Y\&Y re-working of
% Marvosym mentioned below -- a Truetype version and a Mac PS Type 1
% version that will work with ATM.
%
% The Marvosym fount and package are (October 1998) in this location at
% CTAN:
% site (October 1998):
%\begin{verbatim}
% /fonts/psfonts/marvosym/
%\end{verbatim}
%
% A version which is apparently ATM compatible (implying the original
% version from CTAN isn't) is available from here:
%\begin{verbatim}
% http://www.YandY.com/download/marvosym.zip
%\end{verbatim}
% Note that the metrics for this version of Marvosym are slightly
% different to the original; to use this version of Marvosym with
% \packname{eurofont}, you should re-name the file
% \filename{marvosym.tfm} to \filename{fmvr8x.tfm} and put it on your
% tex-fonts path.
%
% Martin Vogel's Web page contains a TrueType version of Marvosym, in
% a format suitable for MS-Windows computers:

%\end{verbatim}
%
% \subsection{\Dvidriver configuration for
% Adobe's Eurofonts and the Marvosym fount} \label{sec:dvidriver_config}
%
% This section contains information on how to configure dvips and
% \OzTeX\ to use Adobe's Eurofonts and the Marvosym fount. I believe
% that pdf\TeX\ can use dvips entries.
%
% You might find it useful to refer to the file \filename{dvidrive.txt}
% that is created by running \LaTeX\ on \filename{eurofont.ins}:
% \filename{dvidrive.txt} contains a plain text version of this
% \dvidriver configuration information, so you can cut and paste the
% lines you need to the appropriate file on your computer.
%
% If you have any problems with this information, or if you have
% information on how to configure other \dvidriver{}s, please let me
% know by email.
%
% \subsubsection{\Dvidriver configuration lines for Adobe's Eurofonts}
%
% This section contains information for configuring \dvidriver{}s to use
% these \PS Type 1 founts; what you need to do is add the given
% lines to a file so that your \dvidriver knows which \PS Type 1 fount
% file (and so on) corresponds to a particular \filename{tfm} file in a
% \filename{dvi} file. In the case of dvips, the file you add lines to
% is typically called \filename{psfonts.map}. In the case of \OzTeX, you
% will normally add lines to the \filename{Default} configuration file
% -- if you also use dvips, you'll add lines to \filename{psfonts.map}
% as well.
%
% Note that versions of dvips before v5.83 have trouble doing partial fount
% downloading with Adobe's Eurofonts. Because of this, I have listed the
% dvips psfont.map entries with `|<<|' and with `|<|': the `|<<|'
% entries prevent dvips attempting to do partial fount downloading with
% that particular fount.
%
% The `|<<|' syntax does not work with all versions of dvips; it does
% work with dvips~v5.78, but doesn't work with v5.70. If you're using a
% pre `|<<|' dvips, you should use the entries with `|<|' and don't use
% partial fount downloading with any document containing Adobe's
% Eurofonts; passing the |-j0| switch to dvips will prevent it from
% doing partial fount downloading if this is normally turned on.
%
% I've asked the author of dvips when the `|<<|' syntax was first introduced,
% and he can't remember.
%
% I am told that pdf\TeX\ can do partial fount downloading using Adobe's
% Eurofonts.
%
% \paragraph{Eurofont configuration lines for MS-Windows and Unix}
%

% |<ulrich@cis.uni-muenchen.de>|, who tells me that you need to re-name

% \subsubsection{\Dvidriver configuration lines for
% Marvosym}\label{sec:dvidriver_config:mvs}
%
% I have been greatly confused while trying to work out how to configure
% \dvidriver{}s to use Marvosym. I think I've got it right, but I can't
% test on anything but my Mac. I'd appreciate an email if you find that
% any of the information below turns out to be wrong.
%
% There are two versions of the Marvosym out there in network land: the
% original, and a version that's been re-worked by Y\&Y. As far as I can
% work out, the Y\&Y version of Marvosym has identical glyphs to the
% original, and differs in that it works properly with ATM and has
% better hinting. This means that the new version should render better
% at low and medium resolutions. In other words, I think the Y\&Y
% version is better than the original. The metrics for the two
% versions are very slightly different to each other, so you should make
% sure you're using the \filename{tfm} file that came with the version
% of the Marvosym fount that you're using.
%
% Dvips \filename{psfonts.map} entries for the original Marvosym fount:
%\begin{verbatim}
% fmvr8x Martin_Vogels_Symbole <marvosym.pfb
% fmvri8x Martin_Vogels_Symbole " .167 SlantFont" <marvosym.pfb
%\end{verbatim}
%
% Dvips \filename{psfonts.map} entries for the Y\&Y `ATM compatible'
% re-worked Marvosym fount:
%\begin{verbatim}
% fmvr8x Marvosym <marvosym.pfb
% fmvri8x Marvosym " .167 SlantFont" <marvosym.pfb
%\end{verbatim}
%
% I have assumed that all \dvidriver{}s that can use \PS Type 1 founts
% can also produce fake italic founts by slanting an upright version.
% Because of this, I have made no provision for \dvidriver{}s that can't
% do this. If you have a \dvidriver that can't fake an italic, please
% let me know and I'll modify the \packname{eurofont} package to take
% this into account, probably by adding another option and writing a
% new \filename{fd} file.
%
% \paragraph{Note for Macintosh users}
%
% A Mac version of the Marvosym fount has been created in \PS Type 1 and
% TrueType versions. It uses the Y\&Y names as above, and
% these lines are be needed for dvips's \filename{psfonts.map} file:
%\begin{verbatim}
% fmvr8x Marvosym <Marvo
% fmvri8x Marvosym " .167 SlantFont" <Marvo
%\end{verbatim}
% And these lines for \OzTeX's default config file:
%\begin{verbatim}
% fmvr8x Marvosym Marvosym nil
% fmvri8x Marvosym Marvosym nil i
%\end{verbatim}
%
% If a version of the original Marvosym fount is ever released for Macs,
% these lines will be needed for dvips's \filename{psfonts.map} file:
%\begin{verbatim}
% fmvr8x Martin_Vogels_Symbole <MartiVogSym
% fmvri8x Martin_Vogels_Symbole " .167 SlantFont" <MartiVogSym
%\end{verbatim}
% And these lines for \OzTeX's default config file:
%\begin{verbatim}
% fmvr8x MartiVogSym "Martin Vogels Symbole" nil
% fmvri8x MartiVogSym "Martin Vogels Symbole" nil i
%\end{verbatim}
%
% \subsection{Metafont founts containing euro symbols}\label{sec:getMFfounts}
%
% The three Metafont sources of euro symbols that I know of are the
% Text Companion founts, the China2e fount, and the Eurosym fount. If
% you know of others, I'd appreciate an email to tell me about them.
%
% The current (October 1998) version of \LaTeX\ is set up to work with
% the relatively new T1 (and TS1) encoded versions of the usual Computer
% Modern founts. If you don't have the `European Computer Modern' and
% `Text Companion' founts -- otherwise known as the EC and TC founts --
% it might be a good idea to get them now: the TS1 encoded Text
% Companion founts are the ones containing euro symbols.
%
% If the above paragraph doesn't make much sense to you, you can find
% out if your \LaTeX\ has access to the European Computer Modern and
% Text Companion founts by \LaTeX ing this file:
%\begin{verbatim}
% \documentclass{article}
% \usepackage[T1]{fontenc}
% \usepackage{textcomp}
% \begin{document}
% Hello world. \texteuro.
% \end{document}
%\end{verbatim}
% If you get no error messages, you have access to both the European
% Computer Modern (EC) and Text Companion (TC) founts.
%
% If not, you can get these founts, as well as the Eurosym and China2e
% founts and packages, from these locations at your nearest CTAN
% site:
%\begin{verbatim}
% /fonts/ec/
% /fonts/eurosym/
% /macros/latex/contrib/supported/china2e/
%\end{verbatim}
%
% \section{Potentially useful extra information}
%
% Most of the ideas in the \packname{eurofont} package are not my own
% invention, and are documented elsewhere. \LaTeX's fount selection
% scheme, for example, is documented in the file
% \filename{fntguide.tex} which is part of the standard \LaTeX\
% distribution. The file \filename{simple-nfss.tex} kept in the
% \filename{info/} directory at CTAN is also useful.
%
% If you're interested in understanding the details of the source code,
% you'll probably find it useful to read \filename{clsguide.tex} (also
% part of the standard \LaTeX\ distribution), as well as Leslie
% Lamport's `\LaTeX, a document preparation system', 2nd edition,
% Addison-Wesley. Donald Knuth's `The \TeX book', also published by

% and Samarin's `The \LaTeX\ Companion', published by Addison-Wesley, is

% substitute for this book.
%
% \subsection{Fount families and series}\label{sec:fountfamilies}
%
% \LaTeXe\ comes with a way of selecting founts called the New Fount
% Selection Scheme (NFSS). Each fount you use is specified by five
% things: encoding, family, series, shape, and size. A typical
% specification is |OT1/ptm/m/n at 12pt|. This means an \lfntname{OT1}
% encoded version of \lfntname{ptm} (Adobe Times) family, \lfntname{m}
% (medium) series, \lfntname{n} (normal upright roman) shape, in a size
% of 12pt. The point of the NFSS is to take a particular fount
% specification -- like |OT1/ptm/m/n at 12pt| -- and work out which
% \filename{tfm} file should be used.
%
% This job is essential, because as far as \TeX\ is concerned, a
% \filename{tfm} file \emph{is} a fount: without a \filename{tfm} file,
% you get no letters on the page. A \filename{tfm} file is just a list
% of sizes of each letter and things like that; the actual letter shapes
% are kept elsewhere. The \dvidriver needs to know which \filename{tfm}
% file corresponds to which `real' fount, which is what dvips's
% \filename{psfonts.map} is for.
%
% What the NFSS does is add a high-level interface to let you select a
% particular \filename{tfm} file without having to deal with any of the
% awkward details -- \LaTeX\ has always had some sort of interface to
% allow this sort of thing, but the NFSS is much better than earlier
% efforts, and much, much easier to set up for a new set of founts.
%
% The precise details of exactly which \filename{tfm} file is to be used
% for each fount specification are contained in the various
% \filename{fd} files installed on your computer (they're kept somewhere
% on the tex-inputs path). \filename{ot1ptm.fd}, for example, is
% consulted in the above example. It says that \filename{ptm7t.tfm}
% should be used for |OT1/ptm/m/n| at all sizes. This doesn't mean that
% you can only get Adobe Times in one size, because \TeX\ will scale the
% fount to the appropriate size -- the instruction to do this is
% included in the \filename{fd} file.
%
% You might be wondering what an encoding is. Well, when you type
% information into a computer, each character you type is given a number
% and this number is stored in memory: this number `is' the character
% you have just typed. The relationship between the characters and
% numbers is called an encoding. ASCII encoding, for example, says that
% the letter `A' has the number 65; `B' has the number 66, and so on. In
% the case of \LaTeX, you have two encodings: the input encoding --
% which is used to translate the input file into \TeX's internal
% encoding (which you can forget about for now); and the output
% encoding, which is used to create the \filename{dvi} file. For
% example, a Mac user might type an \"{o} (number 194) into a
% \filename{tex} file. Assuming that he'd said
% \comname{usepackage[applemac]\ttlb inputenc\ttrb}, that would result
% in the appropriate character appearing in the \filename{dvi} file.
% This character would be represented in the \filename{dvi} file by a
% number 246 if you were using a \lfntname{T1} encoded fount at that
% point. If you were using an \lfntname{OT1} encoded fount, it would be
% represented by a combination of character number 128 (umlaut) placed
% over character number 111 (the letter o). There are many other output
% and input encodings that are commonly used. It is, for example, common
% to use ASCII input encoding, so you have to type |\"{o}| to get \"{o}.
% \LaTeX\ usually sorts out all the details for you so you don't have
% to think about encodings that often.
%
% From the point of view of configuring the \packname{eurofont} package,
% you can probably ignore encodings. The two most common text fount
% encodings used with \LaTeX\ are \lfntname{OT1} and \lfntname{T1}:
% the original 7-bit standard encoding and the newer 8-bit standard
% encoding respectively.
%
% What \packname{eurofont} is most interested in is the fount family
% name. This comes after the encoding: |OT1/ptm|, and is usually a three
% letter abbreviation like \lfntname{ptm} for Adobe Times. The full
% explanation of the naming scheme is presented in the fontname
% documentation\footnote{Available from CTAN: \texttt{/info/fontname/}}.
% In brief, the first letter of this family usually indicates the firm
% that made the fount. Adobe is indicated by a `\lfntname{p}' (for \PS,
% because Adobe created \PS). The next two letters indicates the name of
% the fount. Times is indicated by `\lfntname{tm}'. Not all fount
% families follow this pattern: the Computer Modern families pre-date
% the fontname naming scheme, so (for example) the Computer Modern
% Sanserif family has the name `\lfntname{cmss}'. And some fount families
% named according to the fontname scheme have very strange names. The
% Adobe Euroserif family has the name `\lfntname{zpeur}', the letter
% \lfntname{z} being a prefix meaning `bizarre'.
%
% There's effectively an unlimited range of fount family names. One way
% of finding out what the name is of a particular fount family is using
% \packname{eurofont}'s \comname{showfontfamily} command in your
% document: it'll print the current fount family on the console and in
% the log file. For example, if you \LaTeX\ this file:
%\begin{verbatim}
% \documentclass{article}
% \usepackage{otherfont}% A fictitious package to select a fount
% \usepackage{eurofont}
% \begin{document}
% Blah blah blah
% \showfontfamily
% \end{document}
%\end{verbatim}
% You'll get a message in the log file and the terminal output telling
% you what the fount family used to typeset `Blah blah blah' is.
%
% Another way of finding out a particular fount family name is this:
% files for using different founts with \LaTeX\ -- such as
% \filename{times.sty} -- tend to contain lines like:
%\begin{verbatim}
% \renewcommand{\sfdefault}{phv}
% \renewcommand{\rmdefault}{ptm}
% \renewcommand{\ttdefault}{pcr}
%\end{verbatim}
% This means that the \lfntname{phv} (Adobe Helvetica) family is used
% for \comname{sffamily}, the \lfntname{ptm} family (Adobe Times) family
% is used for \comname{rmfamily}, and the \lfntname{pcr} family (Adobe
% Courier) is used for \comname{ttfamily}. This means you can find out
% which fount family is used by examining the package file you use to
% select it.
%
% If you're interested in the details of producing faked euro
% symbols, the fount series becomes relevant. The normally available
% fount series are just different weights:
% \begin{center}
% \begin{tabular}{ll|ll}
% ul & ultra light & sb & semi bold \\
% el & extra light & b & bold \\
% l & light & bx & bold extended\\
% m & normal (medium) & eb & extra bold \\
% mb & medium bold & ub & ultra bold \\
% db & demi bold & \\
% \end{tabular}
% \end{center}
% Of these, only two are selectable with normal commands.
% \comname{bfseries}, for example, selects the \lfntname{bx} (bold
% extended) series; and \comname{mdseries} selects the \lfntname{m}
% (normal `medium' weight). Most fount families come in two different
% weights only. No normal founts are available in the range of weights
% just listed, although Multiple Master founts (those with a weight
% design axis) can be used in any number of different weights over
% almost any range. If you have produced a Multiple Master fount setup
% that gives you access to the full standard range of \LaTeX\ fount
% series, you are clearly mad\footnote{And probably called something
% like Melissa or Sebastian} and equally clearly don't need me to
% explain anything about the NFSS.
%
% If you want to select something like ultrabold, one way is to say:
%\begin{verbatim}
% \fontseries{ub}\selectfont
%\end{verbatim}
%
% A complication is that some fount families have condensed versions,
% and this has to be indicated by the fount series too. This means
% that the list of `standard' series can be extended to include:
% \begin{center}
% \begin{tabular}{ll|ll}
% ulc & ultra light condensed & dbc & demi bold condensed \\
% elc & extra light condensed & sbc & semi bold condensed \\
% lc & light condensed & bc & bold condensed \\
% mc & normal (medium) condensed & ebc & extra bold condensed \\
% mbc & medium bold condensed & ubc & ultra bold condensed \\
% \end{tabular}
% \end{center}
% Likewise, a fount family might have extended version of some weights
% (Computer Modern Roman's Bold Extended is an example of this), so the
% `standard' list of series must also include variants like
% \lfntname{ulx} for ultra light extended. This is only relevant to
% \packname{eurofont} when it's asked to create a faked euro symbol: it
% has to know which series are bold (or whatever) to decide what
% thickness lines to draw across the C.
%
% \section{How \packname{eurofont} works -- in detail}
% \label{sec:how_it_works}
%
% This section is not meant to be a replacement for the rest of the
% documentation for \TeX nical people. The idea is that this is an
% intermediate step between the usual user documentation and the rather
% eccentrically-commented source code -- it's probably a good idea to
% read the earlier parts of this document before digging in to this
% section.
%
% The \packname{eurofont} package provides two commands meant to be used
% in documents for generating a euro symbol: \comname{euro} which just
% prints a euro symbol, and \comname[amount]{euros} which prints a euro
% symbol (generated by the \comname{euro} command) next to the argument
% of the command, with a small space between the two. The euro symbol is
% to the left of the argument by default: if you pass the
% \optname{right} option to the \packname{eurofont} package, the euro
% symbol is printed to the right of the argument of the command.
%
% The \comname{euros} command uses the \comname{euro} command to
% generate the euro symbol, so everything that applies to the
% \comname{euro} command also applies to the \comname{euros} command.
%
% I see the package code as being in several main parts: the code for
% handling the lists, the \comname{euro} command and supporting
% \comname{make...} commands, the other commands for selecting and
% printing euro symbols, and the code to construct fake euro symbols.
% This is an entirely arbitrary division; I mention it in the hope that
% it might explain the way I've divided up this part of the documentation.
%
% Note that the \comname{make...euro} commands are all meant to be
% called directly by the \comname{euro} command; the idea is to give you
% a `top level' set of commands to modify in the configuration file any
% way you like, while still allowing access to any of the euro symbols
% the \packname{eurofont} package is set up to work with by default:
% the \comname{make...euro} commands are all defined in terms of other
% commands, and it's these other commands that do the job of actually
% printing a euro symbol. You might, for example, change the
% \comname{makechinaeeuro} command to print `EUR':
%\begin{verbatim}
% \newcommand{\makechinaeeuro}{EUR}
%\end{verbatim}
% and use entries in the \comname{chinaeeuro} list to select this, rather
% than the euro symbol I intended. Even so, the `lower level' command
% \comname{chinaeeuro} will be unaffected: it will still produce the
% euro symbol from the China2e fount, and you will still be able to use
% it. For example, you might say:
%\begin{verbatim}
% \newcommand{\pgyeuro}{\chinaeeuro}
%\end{verbatim}
% to get a euro symbol from the China2e fount with Adobe Goudy (family
% name \lfntname{pgy})
%
% A point that might be useful to know is this: the \packname{eurofont}
% package doesn't define the \comname{euro} command when it's loaded
% using the \comname{usepackage\ttlb eurofont\ttrb} command. What
% happens is that \packname{eurofont} defines the \comname{EFeuro}
% command to begin with: \comname{EFeuro} is just \packname{eurofont}'s
% \comname{euro} command under a different name. The \packname{eurofont}
% package arranges for the \comname{euro} command that you use in your
% document to be created later. The way it's done is this:
% \packname{eurofont} adds some code to the \comname{AtBeginDocument}
% hook. This code uses \TeX's \comname{let} command to make the
% \comname{euro} command identical to \comname{EFeuro} at the
% \comname{begin\ttlb document\ttrb} command. Immediately before this,
% the code added by \packname{eurofont} uses \TeX's \comname{let}
% command again to make the \comname{oldeuro} command identical to the
% \comname{euro} command. This means that \packname{eurofont}'s
% definition of \comname{euro} will over-ride any earlier definitions,
% while saving any earlier definitions for you to use. This might also
% explain strange behaviour you encounter if trying to re-define
% \comname{euro} yourself in a document preamble. It's probably best to
% do something like this:
% \label{sec:how_it_works:redefine_euro}
%\begin{verbatim}
% \documentclass{whateveryouwant}
% ...
% \usepackage{eurofont}
% \newcommand{\myeuro}{Some code}
% \AtBeginDocument{\let\euro\myeuro}
% ...
% \begin{document}
%\end{verbatim}
% The \packname{eurosym} package is a special case: if you pass the
% \optname{eurosym} option to \packname{eurofont}, \packname{eurofont}
% uses \comname{let} to make the \comname{ESeuro} command identical to
% \packname{eurosym}'s \comname{euro} command just after
% \packname{eurofont} has loaded \packname{eurosym}. This
% \comname{ESeuro} command appears in \packname{eurofont}'s code in
% various places: remember that it's defined to be whatever the
% \packname{eurosym} package defined the \comname{euro} command to be.
%
% \subsection{The \comname{euro} command}\label{sec:how_euro_works}
%
% The \comname{euro} command works like this: it looks at the current
% fount family (I shall call this \verb|<fam>| for now -- \lfntname{ptm}
% for Adobe Times, \lfntname{cmr} for Computer Modern Roman, and so on),
% and performs the following sequence of tests:
%\begin{verbatim}
%If <fam> is in \userlist, \makeusereuro
% else
% if \<fam>euro exists, \<fam>euro
% else
% if <fam> is in \texteurolist, \maketexteuro
% else
% if <fam> is in \chinaelist, \makechinaeeuro
% else
% if <fam> is in \cmlist, \makecmeuro
% else
% if <fam> is in \serifeurolist, \makeserifeuro
% else
% if <fam> is in \sanseurolist, \makesanseuro
% else
% if <fam> is in \monoeurolist, \makemonoeuro
% else
% if <fam> is in \makefakelighteurolist, \makefakelighteuro
% else
% if <fam> is in \makefakemediumeurolist, \makefakemediumeuro
% else
% if <fam> is in \makefakeheavyeurolist, \makefakeheavyeuro
% else \makedefaulteuro
% fi fi fi fi fi fi fi fi fi fi fi
%\end{verbatim}
% In other words, it first looks to see if the current fount family is
% listed in the \comname{usereurolist}. If it is, it executes the
% \comname{usereuro} command and finishes. If not, it looks to see if a
% command \comname{<fam>euro} exists. For example, if you're typesetting
% with Adobe Times at that point (family name \lfntname{ptm}), it'll
% look for the \comname{ptmeuro} command. If this command exists, it is
% executed and the \comname{euro} command finishes. If not, it looks to
% see if the current fount family is in the \comname{texteurolist}. If
% it is, the \comname{texteuro} command is executed, and the
% \comname{euro} command finishes. This continues to the final test: if
% the current fount family is in the \comname{makefakeheavyeurolist},
% the \comname{makefakeheavyeuro} command is executed, and the
% \comname{euro}command finishes. If it's got to the end of the tests
% and no match has been found, the \comname{defaulteuro} command is
% executed.
%
% It's up to you to define the \comname{makeusereuro} and
% \comname{<fam>euro} commands. All the other \comname{make...euro}
% commands may be re-defined as you see fit, but are defined by the
% \packname{eurofont} package to produce euro symbols.
%
% \subsection{The \comname{make...euro} commands}
%
% What each of these commands does by default is this:
%
% \subsubsection{\comname{maketexteuro}}
% Executes either the \comname{texteuro} command or the
% \comname{makefakeeuro} command. The \comname{texteuro} command is
% normally defined by the \packname{textcomp} package (part of the
% standard \LaTeX\ distribution) to print a euro symbol from the TS1
% encoded complement to the current fount. This TS1 encoded complement
% often does not exist, and even if it does exist, it usually (October
% 1998) does not have a euro symbol. The \comname{makefakeeuro} command
% is described in section~\vref{sec:howitworks:makefakeeuro}. The
% \packname{eurofont} package tries to load the \packname{textcomp}
% package by default; see section~\vref{sec:all_options} for more
% details.
%
% The decision on whether to execute \comname{texteuro} or
% \comname{makefakeeuro} is made like this: the \comname{texteuro}
% command is executed if these three conditions are met: 1)~the current
% fount family is not listed in \comname{faketext\-eurolist}, 2)~the
% \packname{textcomp} package has been loaded, and 3)~that the fount
% definition file \filename{ts1<fam>.fd} exists (where |<fam>| is the
% current fount family name). That \filename{fd} file is the thing that
% tells \LaTeX\ where to find the symbol asked for in the
% \comname{texteuro} command defined by the \packname{textcomp} package:
% if it doesn't exist, the current fount family certainly doesn't have a
% euro symbol available in the expected place.
%
% The decision isn't foolproof: there's no way that \TeX\ can check for
% the existence of a real glyph in a fount (the matter is complicated
% greatly by virtual founts and `missing glyph' rule boxes), so
% \comname{maketexteuro}'s checks mustn't be relied on.
%
% \subsubsection{\comname{makefakeeuro}}
% \label{sec:howitworks:makefakeeuro}
% This command first checks to see if the command
% \comname{<fam>fakeeuro} exists, where |<fam>| is the name of the
% current fount family; if this command exists, it's executed. If not,
% \comname{makefakeeuro} then checks for the presence of the current
% fount family name in (in this order) \comname{EFfakelightlist},
% \comname{EFfakemediumlist}, and \comname{EFfake\-heavylist}. If it finds
% a match, it executes the corresponding \comname{makefake...euro}
% command; these are explained below. If it finds no match, it executes
% the \comname{makefakemediumeuro} command. \comname{makefakeeuro}
% doesn't appear directly in the definition of the \comname{euro}
% command.
%
% \subsubsection{\comname{makechinaeeuro}}
% \label{sec:howitworks:makechinaeeuro}
% Executes the \comname{chinaeeuro} command, which prints a fake
% bold euro symbol created from the China2e fount's euro symbol if the
% current \comname{fontseries} is listed in the
% \comname{EFbold\-serieslist} or the \comname{EFultraboldserieslist},
% and a straight euro symbol from the China2e fount otherwise. The
% \comname{chinaeeuro} command is described in
% section~\vref{sec:howitworks:chinaeeuro}.
%
% \subsubsection{\comname{makecmeuro}}
% \label{sec:howitworks:makecmeuro}
% If you've given the \optname{eurosym} option to the
% \packname{eurofont} package and the \packname{eurosym} package has
% been loaded successfully, \comname{makecmeuro} executes the
% \comname{ESeuro} command which prints the specified \packname{eurosym}
% euro symbol, as described in section~\vref{sec:howitworks:makecmeuro}.
% Otherwise, the \comname{cmeuro} command is executed, which gives you
% either a euro symbol from the text companion founts, or a faked euro
% symbol; this faked euro symbol is made with light rules for Computer
% Modern Roman and medium weight rules for Computer Modern Sanserif
% and Typewriter. The \comname{cmeuro} command is described in
% section~\vref{sec:howitworks:cmeuro}.
%
% \subsubsection{\comname{makeserifeuro}}
% \label{sec:howitworks:makeserifeuro}
% This executes the \comname{serifeuro} command, described in
% section~\vref{sec:howitworks:serifeuro}. By default,
% \comname{serifeuro} executes the \comname{zpeureuro} command,
% described in section~\vref{sec:howitworks:zpeureuro}, which prints a
% euro symbol from Adobe's Euroserif fount. If you have given the
% \optname{marvosym} option to \packname{eurofont} and you have not used
% the \optname{eurosym} option, the \comname{serifeuro} command will
% instead execute the \comname{marvosymserifeuro} command, described in
% section~\vref{sec:howitworks:marvosymserifeuro}: this will try to
% print a seriffed euro symbol from the Marvosym fount. If the current
% fount series is in \comname{EFboldserieslist} or
% \comname{EFultraboldserieslist}, you'll get a faked bold euro from the
% Marvosym fount. The default setup assumes that your \dvidriver can
% print a faked italic version of the Marvosym fount.
%
% If you've given the \optname{eurosym} option to the
% \packname{eurofont} package and the \packname{eurosym} package has
% been loaded successfully, the \comname{serifeuro} command prints the
% specified \packname{eurosym} euro symbol by executing the
% \comname{ESeuro} command. The \comname{ESeuro} command is described in
% section~\vref{sec:howitworks:ESeuro}.
%
% \subsubsection{\comname{makesanseuro}}
% \label{sec:howitworks:makesanseuro}
% This executes the \comname{sanseuro} command, described in
% section~\vref{sec:howitworks:sanseuro}. By default, \comname{sanseuro}
% executes the \comname{zpeusseuro} command, described in
% section~\vref{sec:howitworks:zpeusseuro}, which prints a euro symbol
% from Adobe's Eurosans fount. If you have given the \optname{marvosym}
% option to \packname{eurofont} and you have not used the
% \optname{eurosym} option, the \comname{sanseuro} command will instead
% execute the \comname{marvosymsanseuro} command, described in
% section~\vref{sec:howitworks:marvosymsanseuro}: this will try to print
% a sanserif euro symbol from the Marvosym fount. If the current fount
% series is in \comname{EFboldserieslist} or the
% \comname{EFultraboldserieslist}, you'll get a faked bold euro from the
% Marvosym fount. The default setup assumes that your \dvidriver can
% print a faked italic version of the Marvosym fount.
%
% If you've given the \optname{eurosym} option to the
% \packname{eurofont} package and the \packname{eurosym} package has
% been loaded successfully, the \comname{sanseuro} command prints the
% specified \packname{eurosym} euro symbol by executing the \comname{ESeuro}
% command.
%
% \subsubsection{\comname{makemonoeuro}}
% \label{sec:howitworks:makemonoeuro}
% This executes the \comname{monoeuro} command, described in
% section~\vref{sec:howitworks:monoeuro}. By default,
% \comname{monoeuro} executes the \comname{zpeutteuro} command,
% described in section~\vref{sec:howitworks:zpeutteuro}, which prints a
% euro symbol from Adobe's Euroserif fount. If you have given the
% \optname{marvosym} option to \packname{eurofont} and you have not used
% the \optname{eurosym} option, the \comname{monoeuro} command will
% instead execute the \comname{marvosymmonoeuro} command, described in
% section~\vref{sec:howitworks:marvosymserifeuro}: this will try to
% print a monospaced euro symbol from the Marvosym fount. If the current
% fount series is in \comname{EFboldserieslist} or
% \comname{EFultraboldserieslist}, you'll get a faked bold euro from the
% Marvosym fount. The default setup assumes that your \dvidriver can
% print a faked italic version of the Marvosym fount.
%
% If you've given the \optname{eurosym} option to the
% \packname{eurofont} package and the \packname{eurosym} package has
% been loaded successfully, the \comname{sanseuro} command prints the
% specified \packname{eurosym} euro symbol by executing the \comname{ESeuro}
% command.
%
% \subsubsection{\comname{makefakelighteuro}}
% \label{sec:howitworks:makefakelighteuro}
% If the command \comname{<fam>fakeeuro} exists (where |<fam>| is the
% name of the current fount family), execute it. Otherwise, execute the
% \comname{fakelighteuro} command, which prints a euro symbol faked from
% a letter C with two light rules printed over it; you can find out more
% about this in section~\vref{sec:howitworks:fakelighteuro}. The
% \comname{makefakelighteuro} command is unaffected by the
% \optname{eurosym} option.
%
%
% \subsubsection{\comname{makefakemediumeuro}}
% \label{sec:howitworks:makefakemediumeuro}
% If the command \comname{<fam>fakeeuro} exists (where |<fam>| is the
% name of the current fount family), execute it. Otherwise, execute the
% \comname{fakemediumeuro} command, which prints a euro symbol faked
% from a letter C with two light rules printed over it; you can find out
% more about this in section~\vref{sec:howitworks:fakemediumeuro}. The
% \comname{makefakemediumeuro} command is unaffected by the
% \optname{eurosym} option.
%
% \subsubsection{\comname{makefakeheavyeuro}}
% \label{sec:howitworks:makefakeheavyeuro}
% If the command \comname{<fam>fakeeuro} exists (where |<fam>| is the
% name of the current fount family), execute it. Otherwise, execute the
% \comname{fakeheavyeuro} command, which prints a euro symbol faked
% from a letter C with two light rules printed over it; you can find out
% more about this in section~\vref{sec:howitworks:fakeheavyeuro}. The
% \comname{makefakeheavyeuro} command is unaffected by the
% \optname{eurosym} option.
%
% \subsubsection{\comname{makedefaulteuro}}
% \label{sec:howitworks:makedefaulteuro}
% Executes the \comname{makefakeeuro} command. This usually prints a
% euro faked with medium weight rules. See
% section~\vref{sec:howitworks:makefakeeuro} for more details.
%
% \subsection{Other commands to print euro symbols}

% \subsubsection{\comname{chinaeeuro}}
% \label{sec:howitworks:chinaeeuro}
%
% This prints the euro symbol from the China2e fount. There is only one
% euro character available, in the upright shape and medium weight only.
% This command uses the \comname{SelectOnWeight} command to print either
% a China2e euro symbol in its natural state (for light and medium
% weights), or a `poor man's bold' version for bold and ultra bold
% weights.
%
% The \comname{SelectOnWeight} command is described in
% section~\vref{sec:howitworks:selectonweight}.
%
% \subsubsection{\comname{cmeuro}}
% \label{sec:howitworks:cmeuro}
%
% The \comname{cmeuro} command executes the \comname{texteuro} command to
% print a euro symbol from the TS1 encoded complement of the current
% fount if these three conditions are met: 1) the current fount family
% is not in the \comname{faketexteurolist}; 2) the command
% \comname{texteuro} exists; and 3) the file \filename{ts1<fam>.fd}
% exists, where \filename{<fam>} is the name of the current fount
% family. If all three conditions are not met, \comname{cmeuro} executes
% the \comname{makefakeeuro} command to print a faked euro symbol; this
% command is described in section~\vref{sec:howitworks:makefakeeuro}.
%
% \subsubsection{\comname{EFeuro}}
% \label{sec:howitworks:EFeuro}
%
% This is the name under which the \comname{euro} command is defined
% originally; the \packname{eurofont} package adds some code to the
% standard \LaTeX\ \comname{AtBeginDocument} hook that makes the
% \comname{euro} command equivalent to the \comname{EFeuro} command
% (using the primitive \TeX\ \comname{let} command). This code added to
% the \comname{AtBeginDocument} hook is executed, unsurprisingly, at the
% \comname{begin\ttlb document\ttrb} command. It's best not to use the
% \comname{EFeuro} command yourself unless you have a particular need
% to, but if you're writing a class or package file that uses
% \packname{eurofont}, you might have such a need.
%
% The \comname{EFeuro} command is identical to the \comname{euro}
% command, but they are different commands. If you want to change the
% \comname{euro} command in your document, you should do so after the
% \comname{begin\ttlb document\ttrb} command. One suggestion on how to
% do this is in section~\vref{sec:how_it_works:redefine_euro}. This way
% of re-defining the \comname{euro} command means you still have access
% to \packname{eurofont}'s original \comname{euro} command under the
% name \comname{EFeuro}. The \comname{EFeuro} command shouldn't be used
% directly in a \LaTeX\ document. It's not that anything terrible will
% happen if you do, just that \LaTeX\ convention states that commands
% with mixed-case names are meant for use by class and package writers
% only, and it seemed right to me to add this restriction to the
% \comname{EFeuro} command.
%
% \subsubsection{\comname{ESeuro}}
% \label{sec:howitworks:ESeuro}
%
% If you tell the \packname{eurofont} package to load the
% \packname{eurosym} package, \packname{eurofont} makes the
% \comname{ESeuro} command identical to the \comname{euro} command
% defined by \packname{eurosym}. This means that \packname{eurosym}'s
% \comname{euro} command is still available as \comname{ESeuro}, even
% though \packname{eurofont} re-defines the \comname{euro} command to be
% something completely different. It's probably best not to use the
% \comname{ESeuro} command unless you have no choice in the matter, as
% is often the case when writing package files.
%
% In case you're wondering, the \comname{ESeuro} command will be the
% same as the \comname{oldeuro} command if \packname{eurofont} has
% loaded \packname{eurosym}.
%
% \subsubsection{\comname{oldeuro}}
% \label{sec:howitworks:oldeuro}
%
% The \packname{eurofont} package adds another bit of code to the
% \comname{AtBeginDocument} hook: this code not only sets the
% \comname{euro} command to be whatever \comname{EFeuro} has been
% defined as (as mentioned in section~\vref{sec:howitworks:EFeuro}), but
% just before that, the code sets the \comname{oldeuro} command to be
% whatever the \comname{euro} command was at that instant. This means
% that any package which has defined a \comname{euro} command has not
% wasted its effort: its command is still available as
% \comname{oldeuro}.
%
% As mentioned above, the \comname{ESeuro} command will be the
% same as the \comname{oldeuro} command if \packname{eurofont} has
% loaded \packname{eurosym}.
%
%
% \subsubsection{\comname{sanseuro}}
% \label{sec:howitworks:sanseuro}
%
% Depending on what you've asked for in the options to the
% \packname{eurofont} package, this command executes one of three
% commands. By default, or if you've used the \optname{adobeeurofonts}
% option, it executes \comname{zpeusseuro}; if you've used the
% \optname{marvosym} option, it executes \comname{marvosymsanseuro}; and
% if you've used the eurosym option (which over-rides the other two), it
% executes \comname{ESeuro}.
%
% The \comname{zpeusseuro} command is described in
% section~\vref{sec:howitworks:zpeusseuro}; the
% \comname{marvosymsans\-euro} is described in
% section~\vref{sec:howitworks:marvosymsanseuro}; and the
% \comname{ESeuro} command is described in
% section~\vref{sec:howitworks:ESeuro}.
%
% \subsubsection{\comname{serifeuro}}
% \label{sec:howitworks:serifeuro}
%
% Depending on what you've asked for in the options to the
% \packname{eurofont} package, this command executes one of three
% commands. By default, or if you've used the \optname{adobeeurofonts}
% option, it executes \comname{zpeureuro}; if you've used the
% \optname{marvosym} option, it executes \comname{marvosymserifeuro}; and
% if you've used the eurosym option (which over-rides the other two), it
% executes \comname{ESeuro}.
%
% The \comname{zpeureuro} command is described in
% section~\vref{sec:howitworks:zpeureuro}; the
% \comname{marvosymserif\-euro} is described in
% section~\vref{sec:howitworks:marvosymserifeuro}; and the

% section~\vref{sec:howitworks:ESeuro}.
%
% \subsubsection{\comname{monoeuro}}
% \label{sec:howitworks:monoeuro}
%
% Depending on what you've asked for in the options to the
% \packname{eurofont} package, this command executes one of three
% commands. By default, or if you've used the \optname{adobeeurofonts}
% option, it executes \comname{zpeutteuro}; if you've used the
% \optname{marvosym} option, it executes \comname{marvosymmonoeuro}; and
% if you've used the eurosym option (which over-rides the other two), it
% executes \comname{ESeuro}.
%
% The \comname{zpeutteuro} command is described in
% section~\vref{sec:howitworks:zpeureuro}; the
% \comname{marvosymmono\-euro} is described in
% section~\vref{sec:howitworks:marvosymmonoeuro}; and the
% \comname{ESeuro} command is described in
% section~\vref{sec:howitworks:ESeuro}.
%
% \subsubsection{\comname{zpeureuro}}
% \label{sec:howitworks:zpeureuro}
%
% This command prints a euro symbol from one of Adobe's four Euroserif
% founts (Roman, Italic, Bold, or Bold Italic). The selection is done
% using \LaTeX's usual fount selection mechanism.
%
% \subsubsection{\comname{zpeusseuro}}
% \label{sec:howitworks:zpeusseuro}
%
% This command prints a euro symbol from one of Adobe's four Eurosans
% founts (Roman, Italic, Bold, or Bold Italic). The selection is done
% using \LaTeX's usual fount selection mechanism.
%
% \subsubsection{\comname{zpeutteuro}}
% \label{sec:howitworks:zpeutteuro}
%
% This command prints a euro symbol from one of Adobe's four Euromono
% founts (Roman, Italic, Bold, or Bold Italic). The selection is done

%
% \subsubsection[\comname{marvosymeuro}]
% {\comname{marvosymeuro}\comarg{char}}
% \label{sec:howitworks:marvosymeuro}
%
% This command is used by \comname{marvosymserifeuro} (and friends) to
% print a euro symbol from the Marvosym fount. Like the
% \comname{chinaeeuro} command, it uses the \comname{SelectOnWeight}
% command -- covered in section~\vref{sec:howitworks:selectonweight} --
% to print a normal euro symbol for medium and light weight founts, and
% produces a `poor man's bold' version when you're using a bold or ultra
% bold fount.
%
% The \comname{marvosymeuro} command takes a single argument, which is
% the number of the character to be printed: 99 for the sanserif euro symbol,
% 100 for the monospaced euro symbol, and 101 for the seriffed euro symbol.
%
% \subsubsection{\comname{marvosymsanseuro}}
% \label{sec:howitworks:marvosymsanseuro}
%
% The \comname{marvosymsanseuro} command prints a sanserif euro
% symbol from the Marvosym fount by executing
% \comname{marvosymeuro\ttlb 99\ttrb}.
%
% \subsubsection{\comname{marvosymserifeuro}}
% \label{sec:howitworks:marvosymserifeuro}
%
% The \comname{marvosymsanseuro} command prints a seriffed euro
% symbol from the Marvosym fount by executing
% \comname{marvosymeuro\ttlb 101\ttrb}.
%
% \subsubsection{\comname{marvosymmonoeuro}}
% \label{sec:howitworks:marvosymmonoeuro}
%
% The \comname{marvosymsanseuro} command prints a monospaced euro
% symbol from the Marvosym fount by executing
% \comname{marvosymeuro\ttlb 100\ttrb}.
%
% \subsubsection{\comname{cmrfakeeuro}}
% \label{sec:howitworks:cmrfakeeuro}
%
% This command creates a euro symbol faked with light rules, using the
% \comname{fakelight\-euro} command which is described in
% section~\vref{sec:howitworks:fakelighteuro}. Note that the
% \comname{euro} command will execute \comname{<fam>fakeeuro} (where
% |<fam>| is the current fount family) if it's asked to fake a euro
% symbol using any of the \comname{makefake...euro} commands. This means
% that you need to re-define \comname{cmrfakeeuro} if you want to change
% the sort of faked euro symbol you get with Computer Modern Roman; just
% putting |cmr| in (say) \comname{fakemediumlist} won't do the job.
%
% \subsubsection{\comname{cmssfakeeuro}}
% \label{sec:howitworks:cmssfakeeuro}
%
% This command creates a euro symbol faked with medium rules, using the
% \comname{fake\-mediumeuro} command which is described in
% section~\vref{sec:howitworks:fakemediumeuro}. Note that the
% \comname{euro} command will execute \comname{<fam>fakeeuro} (where
% |<fam>| is the current fount family) if it's asked to fake a euro
% symbol using any of the \comname{makefake...euro} commands. This means
% that you need to re-define \comname{cmssfakeeuro} if you want to
% change the sort of faked euro symbol you get with Computer Modern
% Sanserif; just putting |cmss| in (say) \comname{fakelightlist} won't
% do the job.
%
% \subsubsection{\comname{cmttfakeeuro}}
% \label{sec:howitworks:cmttfakeeuro}
%
% This command creates a euro symbol faked with medium rules, using the
% \comname{fake\-mediumeuro} command which is described in
% section~\vref{sec:howitworks:fakemediumeuro}. Note that the
% \comname{euro} command will execute \comname{<fam>fakeeuro} (where
% |<fam>| is the current fount family) if it's asked to fake a euro
% symbol using any of the \comname{makefake...euro} commands. This means
% that you need to re-define \comname{cmttfakeeuro} if you want to
% change the sort of faked euro symbol you get with Computer Modern
% Typewriter; just putting |cmtt| in (say) \comname{fakelightlist} won't
% do the job.
%
% \subsubsection{\comname{pzcfakeeuro}}
% \label{sec:howitworks:pzcfakeeuro}
%
% This command creates a euro symbol faked with medium rules, using the
% \comname{fakemediumeuro[-0.1ex]} command. The optional argument
% lowers the height of the cross-strokes by 0.1\,ex to match the C in
% Zapf Chancery.
%
% Note that the \comname{euro} command will execute
% \comname{<fam>fakeeuro} (where |<fam>| is the current fount family) if
% it's asked to fake a euro symbol using any of the
% \comname{makefake...euro} commands. This means that you need to
% re-define \comname{pzcfakeeuro} if you want to change the sort of
% faked euro symbol you get with Zapf Chancery; just putting |pzc| in
% (say) \comname{fakelightlist} won't do the job.

% \subsection{Commands used to produce faked euro symbols}
%
% \subsubsection[\comname{fakeheavyeuro}]
% {\comname{fakeheavyeuro}\comoptarg{lift}\comoptarg{slant corr}}
% \label{sec:howitworks:fakeheavyeuro}
%
% This is one of three similar commands: this command prints a euro
% symbol faked with heavy rules. It's executed by the \comname{euro}
% command if the current fount family is in the \comname{fakeheavylist}.
% It takes two optional arguments: the first one, \comoptarg{lift},
% lifts the cross-strokes of the faked euro symbol by the specified
% length; the default length is 0\,pt. The second optional argument,
% \comoptarg{slant corr}, is a percentage factor by which the nominal
% slant of the fount is multiplied by before calculating the horizontal
% position of the rules. Its default value is 100 (i.e., multiply the
% slant by $100/100 = 1$); this argument never has any effect on upright
% founts because they have no slant.
%
% If you pass one optional argument to \comname{fakeheavyeuro}, it is
% interpreted as being the \comoptarg{lift} argument.
%
% \comname{fakeheavyeuro} is defined to be one of these three:

% \optname{bigslantfakeeuro} & \comname{heavyruleeurobigslant} \\
% \end{tabular}
% \end{center}
% The optional argument to \comname{fakeheavyeuro} is passed as the
% first argument (rule lift) to the given \comname{heavyrule\-euro...}
% command; it's 0\,ex by default. The second argument (slant
% correction factor) to the \comname{heavyrule\-euro...} command is
% left blank, so it defaults to 100. See
% section~\vref{sec:howitworks:EFruleeuro} for more about this.
%
% This command was written for the sake of symmetry more than
% anything else; I would be surprised if anyone found a real use for

%
% \subsubsection[\comname{fakelighteuro}]

%
% \subsubsection[\comname{fakemediumeuro}]

% \label{sec:howitworks:fakemediumeuro}

% left blank, so it defaults to 100. See
% section~\vref{sec:howitworks:EFruleeuro} for more about this.
%
% \subsubsection{\comname{EFruleeuro}}\label{sec:EFruleeuro}
% \label{sec:howitworks:EFruleeuro}
%
% The command generates a euro symbol from a `C' with a pair of rules
% drawn on top of it. \comname{EFruleeuro} is not meant to be used in
% documents directly; if you need it, you should follow the
% \packname{eurofont} package's example and use it in the definition of
% a new command to generate a euro symbol. The
% \comname{mediumruleeuronorm} command and others show you a way of
% doing this.
%
% \comname{EFruleeuro} has six arguments:
% \begin{center}
%\begin{tabbing}
% \comname{EFruleeuro}\= \\
% \> \comarg{backshift \%age}\comarg{top rule width \%age}\relax
% \comarg{bottom rule width \%age}\\
% \> \comarg{rule thickness}\comarg{rule vertical spacing}\relax
% \comarg{rule vertical offset}\\
% \> \comarg{slant correction factor \%age}\\
%\end{tabbing}
% \end{center}
%
% The first three arguments are numbers which are interpreted as a
% percentage of the width of a letter `C' in the current fount. The next
% three arguments are normal \LaTeX\ lengths. The final argument is
% another number that's interpreted as a percentage: it's the percentage
% by which the nominal slant of a fount (as specified in the
% \filename{tfm} file) is multiplied by before working out the
% horizontal position of the cross-strokes of a faked euro symbol; if
% this slant correction factor argument is left blank, it defaults to
% 100 (multiply by $100/100 = 1$, so it has no effect), which is what it
% should be most of the time. This slant correction factor never has any
% effect on upright founts, since they have a slant of 0.
%
% The \comarg{rule vertical offset} and \comarg{slant correction factor
% \%age} arguments are needed because the letters as printed are
% sometimes not quite what the metrics files would have you believe.
%
% The way the whole thing works is this: the \comname{EFruleeuro}
% command begins by putting a letter `C' on the page. It then backs up
% by |<backshift>|, and draws the two rules. Each rule is
% |<rule thickness>| thick, and the centre lines of the rules are
% separated by a vertical distance of |<rule spacing>| (if this
% dimension is 0\,pt, the rules are printed on top of each other and it
% appears that you only have one rule printed). The top rule has a
% horizontal length of |<top rule width>|, and the bottom rule has a
% horizontal length of |<bottom rule width>|. The rules are positioned
% half-way up the `C', plus |<rule vertical offset>|; this parameter is
% needed because some letters have metrics that don't quite tie up with
% reality. For example, the C in Zapf Chancery is actually lower than
% the metrics would suggest, so \packname{eurofont}'s calculations go
% awry and a `hand-correction' of -0.1\,ex needs to be applied. The
% following code is executed by \packname{eurofont}'s
% \comname{pzcfakeeuro} command:
%\begin{verbatim}
% \EFruleeuro{110}{80}{72}{0.04ex}{0.27ex}{-0.1ex}{}
%\end{verbatim}
% This creates a euro symbol faked from a `C' with a pair of horizontal
% rules drawn across it.
%
% These rules have their left-hand edge 110\% of the width of the C to
% the left of the right-hand edge of the C. The top rule has a width of
% 80\% of the width of the C; the bottom rule has a width of 72\% of the
% width of the C.
%
% The rules are 0.04\,ex thick, and the distance between the centre
% lines of the rules is 0.27\,ex. The centre line of the pair of rules
% is usually half way up the C according to the fount metrics; in this
% case, these rules are shifted down from this position by 0.1\,ex.
%
% If the C used by \comname{EFruleeuro} is an italic C, the code to
% place the rules takes this into account: it shifts the rules an
% appropriate amount to the right. The rules are also staggered slightly
% to match the slant of the C -- rather than put both rules directly
% above each other at the specified position (taking the italic
% correction into account), the top rule is placed a touch to the
% right and the bottom rule a touch to the left.
%
% And this brings me on to the final parameter: the slant correction
% factor. This is needed because some founts have italic or oblique
% versions in which the slant angle specified in the fount metrics file
% doesn't match the real slant of the printed letters. I have no idea
% why this is the case, but I do know that it means that
% \comname{EFruleeuro}'s careful calculations to place the rules
% correctly produce ugly results when working with these slanted
% founts. This slant correction factor is the percentage by which the
% slant parameter is scaled by. If the rules are being printed too far
% to the left (so that they protrude out the back of the C too far), you
% might try something like this:
%\begin{verbatim}
% \EFruleeuro{110}{80}{72}{0.04ex}{0.27ex}{0ex}{200}
%\end{verbatim}
% which works very well with Adobe Optima -- the line above tells the
% command to work on the basis that the slant is twice as great as
% specified in the metrics file. Since the \packname{fontinst}-generated
% \filename{tfm} file has the slant as $11^{\circ}$ ($1^{\circ}$ less
% than in the \filename{afm} file due to rounding errors), and the slant
% I measured is $21^{\circ}$, you can see that this should work well;
% if you have this fount youself, you will see that it does indeed work
% very well.
%
% On the other hand, Bitstream Optima has a specified slant of
% $10^{\circ}$, but a measured slant of $5^{\circ}$. This means the
% rules are placed too far to the right, so they don't protrude out the
% back of the C far enough. The obvious thing to try in this case is:
%\begin{verbatim}
% \EFruleeuro{110}{80}{72}{0.04ex}{0.27ex}{0ex}{50}
%\end{verbatim}
% which is a definite improvement but far from perfect. This is because
% the italic C in this fount is positioned further to the left than
% expected for reasons which are rather involved. There's no easy
% and good way to deal with this without adding yet another parameter to
% the \comname{EFruleeuro} command, which I decided wasn't justified. In
% the case of Bitstream Optima, you might prefer the results you get
% with a slant correction factor of 25\% or perhaps even 0\%.
%
% A final note: in an attempt to reduce the Byzantine complexity of the
% \comname{EFruleeuro} command to manageable levels, I have assumed that
% the cross-strokes do not extend beyond the right-hand limit of the
% letter `C' which they're printed over. This shouldn't cause any
% problems unless you do something strange.
%
% \subsubsection[\comname{mediumruleeuronorm}]
% {\comname{mediumruleeuronorm}\comarg{lift}\comarg{slant corr}}
% \label{sec:howitworks:mediumruleeuronorm}
%
% This command uses the \comname{SelectOnWeight} command (see
% section~\vref{sec:howitworks:selectonweight}) to print a faked euro
% symbol intended to match a medium weight fount family like Times:
% thicker rules are used for bolder founts in the family, and thinner
% rules are used for lighter founts in the family. The two rules drawn
% across the C have slightly different lengths, approximately the same
% as in the official euro symbol.
%

% {\comname{lightruleeuronorm}\comarg{lift}\comarg{slant corr}}
% \label{sec:howitworks:lightruleeuronorm}
%
% This command behaves the same as \comname{mediumruleeuronorm} (see

%
% \subsection{Other supporting commands}
%
% \subsubsection{\comname{showfontfamily}}
% \label{sec:howitworks:showfontfamily}
%
% This command displays the current fount family name on the console,
% and also notes the same information in the log file. It's meant to
% be used if you're configuring \packname{eurofont}, but aren't sure
% what a particular fount family name is.
%
% If you don't know what a fount family name is in \LaTeX, have a look
% at section~\vref{sec:fountfamilies}.
%
% \subsubsection[\comname{SelectOnWeight}]
% {\comname{SelectOnWeight}
% \comarg{light}\comarg{medium}\comarg{bold}\comarg{ultrabold}}
% \label{sec:howitworks:selectonweight}
%
% This command takes four arguments: the first is executed if the
% current fount series is listed in \comname{lightserieslist}; the
% second if the current fount series is in the
% \comname{mediumserieslist}; the third if it's in the
% \comname{boldserieslist}; and the fourth if it's in the
% \comname{ultraboldserieslist}. If the current fount series isn't
% listed in any of these lists, the second argument (used for medium
% weight founts) is executed.
%
% A typical use of \comname{SelectOnWeight} is this:
%\begin{verbatim}
% \newcommand{\mediumruleeuronorm}[2]{%
% \SelectOnWeight%
% {\EFruleeuro{110}{80}{72}{0.04ex}{0.27ex}{#1}{#2}}% light
% {\EFruleeuro{110}{80}{72}{0.07ex}{0.27ex}{#1}{#2}}% medium
% {\EFruleeuro{110}{80}{72}{0.14ex}{0.27ex}{#1}{#2}}% bold
% {\EFruleeuro{110}{80}{72}{0.18ex}{0.27ex}{#1}{#2}}% ultra bold
% }
%\end{verbatim}
% This defines the \comname{mediumruleeuro} command so that it'll print
% one of four different faked euro symbols, depending on the weight of the
% current fount: lighter weight founts get a euro symbol faked with lighter
% rules; the heavier the fount, the heavier the rules. If the fount
% series isn't in any of the lists, you get the rules used for the medium
% weight series.
%
% Section~\vref{sec:config} shows what's in the four different
% \comname{EF...serieslist} commands by default.
%
% \subsubsection[\comname{EFaddtolist}]
% {\comname{EFaddtolist}\comarg{list name}\comarg{items to add}}
% \label{sec:howitworks:EFaddtolist}
%
% This command takes two arguments: the first argument is the name of a
% list (which must have already been defined as a \TeX\ command), and
% the second argument is a comma delimited list of items to add to the
% list. For example:
%\begin{verbatim}
% \EFaddtolist{\sanslist}{pag,phv,psy,pzd}
%\end{verbatim}
% adds four items to the list called \comname{sanslist}. The list ends
% up containing the given items with a special delimiter to make it
% easier to examine the list using \TeX\ code. A check is made to ensure
% that each item is unique: if you tried to put (say) \lfntname{ptm}
% (Adobe Times) onto the list twice, you'd only end up with one instance
% of \lfntname{ptm} in the list. No warnings are made when this happens.
%
% \subsubsection[\comname{EFiftexteuroexists}]
% {\comname{EFiftexteuroexists}\comarg{if true}\comarg{if false}}
% \label{sec:howitworks:EFiftexteuroexists}
%
% This command takes two arguments. It's used by \comname{maketexteuro}
% and \comname{cmeuro} like this:
%\begin{verbatim}
% \EFiftexteuroexists{\texteuro}{\makefakeeuro}}
%\end{verbatim}
% What happens is that three tests are made: if the current fount family
% is not listed in the \comname{faketexteurolist}, the
% \comname{texteuro} command exists, and a TS1 encoded \filename{fd} file
% exists for the current fount family, then the first argument is
% executed (\comname{texteuro} in this example). If any of these tests
% fails, then the second argument (\comname{makefakeeuro} in this
% example) is executed.
%
% The idea is that if there's a good chance that the \comname{texteuro}
% command will print something useful, then the first argument is
% executed; the second argument is executed otherwise.
%
% The \comname{texteuro} command is defined by the standard
% \LaTeX\ \packname{textcomp} package which \packname{eurofont} tries to
% load by default. The TS1 encoded \filename{fd} file searched for is
% \filename{ts1<fam>.fd}, where |<fam>| is the name of the current fount
% family.
% \subsubsection[\comname{EF@pmb}]{\comname{EF@pmb}\comarg{text}}
% \label{sec:howitworks:EFpmb}
% This command, not meant to be used in documents, is one of the two
% commands the \packname{eurofont} package uses to print faked bold
% characters. What it does is print six copies of its argument, each
% copy offset from the others by a small amount in a hexagonal
% arrangement. The other command to do this job, \comname{EF@pmsb}, is
% identical except that it uses a slightly smaller vertical offset to
% produce better results with the Marvosym euro symbols.
%
% This fakery is no substitute for a real bold symbol, but it's much
% better than the `poor man's bold' used in the TeXbook and the standard
% \LaTeX\ \packname{bm} package. The \packname{eurofont} package's
% \comname{EF@pmb} command produces tolerable results over the full
% range I've tested it: sizes from 5\,pt to 90\,pt; whereas the
% alternative three copy poor man's bold doesn't work at all well at
% large sizes. Thanks are due to Donald Arseneau for suggesting a six
% copy method.
%
% If you're interested, the actual code can be found in
% section~\vref{sec:code:EFpmb}.

% \section{The code itself}
%
% To the interested reader: the code below grew rather than being
% designed and constructed according to a plan. This is reflected in the
% curious structure and eccentric comments; the comments were written
% for the chap who wrote the code, rather than anyone else. There's a
% fair bit of redundant code left (commented out) and quite a lot of
% debugging reports and development notes left in -- these are me
% talking to myself, so don't be worried if you see something
% inexplicable.
%
% One problem with the documented code is that the visual formatting I
% used means that quite a lot of lines are longer than 72 characters, so
% they won't fit within the normal width of the text. There are
% therefore rather a lot of overfull \comname{hboxes} below. I can't see
% any easy way round this, so I have cheated and set \comname{hfuzz} to
% a large value to suppress the warnings.
%
% Say `hello' to the nice \LaTeX\ program. Who am I, and what do I need?
% This package might work with any version of \LaTeXe, but I've
% only tested it with the June 1998 release. For best results, you
% need the ec founts andthe \packname{textcomp} package (part of recent
% \LaTeX s).

% \subsection{Faking a bold character}
% \label{sec:code:EFpmb}
%
% Original comments:
% |\EF@pmb| fakes bold; modified from the \TeX book
%
% I don't pretend to understand it all, but this seems to do the job
% better, and ensures that the width taken by the box is the width taken
% by the printed glyphs. This is used by |\marvosymeuro|
% Original code:
%\begin{verbatim}
% \def\EF@pmb#1{\makebox{\setbox\@tempboxa=\hbox{#1}%
% \kern0em\copy\@tempboxa\kern-\wd\@tempboxa
% \kern.025em\raise.0216em\copy\@tempboxa\kern-\wd\@tempboxa
% \kern.025em\box\@tempboxa }}
%\end{verbatim}
%
% This code produces a better faked bold; the idea of using a hexagonal
% arrangement was suggested by Donald Arseneau. You can probably tell
% I wrote the |\EF@pmb| macro myself :-) I might move to an
% octagonal arrangement later on.
%
% Marvosym complicates matters; a vertical shift of |0.866 x 0.020em|
% makes the horizontal strokes collide when you fake a bold Marvosym
% euro symbol. The solution is to move away from a regular hexagon and
% use a smaller vertical shift.
%
% So now there's two commands: \comname{EF@pmb} for normal fake bold,
% and \comname{EF@pmsb} (semi bold) for the Marvosym euro symbols.
% It's only slightly less heavy than the usual version.

% (default) will set |\monoeuro| (etc) to use adobe glyphs.
