% \begin{abstract}
% \noindent This package allows you to use alphanumeric section
% numbering, e.g. A. Introduction; III. International Law. It's
% output is similar to alphanum.sty, but you can use the standard
% \LaTeX\ sectioning commands. Thus it is possible to switch numbering
% schemes easily. Greek letters, double letters (bb) and different
% delimiters around them are supported.

%
% \section{Options}
% \label{sec:options}
%
% There is only one option: If you specify |usehighlevels|, then the
% numbers for every heading will start with the numbers of the superior
% levels, as without the package (e.g. A.II.3.(a) Important Section).
% Without the option, only the number of the current section level is
% used, e.g. (a) Important Section. This seems to be common with
% alphanumeric numbering.
%
% \section{Specifying the numbering scheme}
% \label{sec:spec-numb-scheme}
%
% You specify the numbering scheme for the headings with the macro
% \begin{verbatim}
% \alnumsecstyle{<list of one-letter-specifiers>}
% \end{verbatim}
% with the following specifiers:
% \begin{center}
% \begin{minipage}{0.8\textwidth}\renewcommand*{\thempfootnote}{\arabic{mpfootnote}}
% \begin{description}
% \item[a or n] stands for \textbf{arabic} number: 6
% \item[R] stands for an uppercase \textbf{Roman} number: VI
% \item[r] stands for a lowercase \textbf{roman} number: vi
% \item[L] stands for an uppercase \textbf{Letter}: A
% \item[l] stands for a lowercase \textbf{letter}: a
% \item[g] is for \textbf{greek} letter: $\alpha$
% \item[d] is for two lowercase letters (\textbf{doubleletter}): aa, bb
% \item[b] for two greek letters (\textbf{doublegreek})\footnotemark: $\alpha\alpha$
% \end{description}
% \end{minipage}
% \end{center}
% \footnotetext{The b is from \emph{bis}, latin for "twice", since the
% greek word would also yield a \textbf{d}.}
%
% The numbers and letters are all followed by a period per default, if
% you want to change this, use the macro
% \begin{verbatim}
% \surround<name>{<before>}{<after>}
% \end{verbatim}
% Instead of |<name>|, put the word given in boldface in the list above
% (case matters!), |<before>| and |<after>| will be typeset around the
% number of type name.
%
% If you use some number types twice, e.g. arabic numbers for the second
% and fifth level: |\alnumsecstyle{LaRla}|, you might want to
% distinguish between the two numbers by their separators. To achieve
% this, you give the separators for lower levels in the optional
% argument(s) to |\surround<name>|. In the example, you might use
% |\surroundarabic[(]{}{)}| to achieve A. 2) III. d. (4) or
% |\surroundarabic[(][)]{}{.}| for A. 2. III. d. (4). Note, however,
% that alnumsec does \emph{not} recognize that a number type has yet
% been used and that it now should use the alternative separators.
% Instead, you have to specify the first level for which alternative
% separators should be used with the command
% |\otherseparators{<level>}|. In \LaTeX, chapter, if defined, has
% level 0, section has 1 and so on down to subparagraph with level
% 5. Therefore, in the above example, |\otherseparators{5}| would
% work, but |\otherseparators{3}| as well.
%
% Please note that |\alnumsecstyle| does not change the numbering
% scheme of figures or tables (yet).
% So if a |report| or |book| like document class will be used,
% one can get double periods there.
% But this can be corrected easily, for example the |figure| counter
% representation is usually defined as something like
% \begin{quote}
% |\newcommand\thefigure{%|\\
% | \ifnum\value{chapter}>0 \thechapter.\fi \arabic{figure}}|
% \end{quote}
% So to remove the extra period here one can insert
% \begin{quote}
% |\renewcommand\thefigure{%|\\
% | \ifnum\value{chapter}>0 \thechapter\fi \arabic{figure}}|
% \end{quote}
% right after the use of |\alnumsecstyle|. (same for tables)
%
%
% \section{Sectioning levels to use}
% \label{sec:sect-levels-use}
%
% Many people that use alphanumeric sectioning numbers also seem to use
% many, many levels of sectioning commands - alnumsec.sty can handle
% this. If you only use the levels that are defined in the standard
% classes (i.e. from |\chapter| or |\section| to |\subparagraph|), you
% don't have to do anything. |\part| is not treated at all by
% alnumsec.sty.
%
%\newcommand*{\labday}{\textbackslash\texttt{labday}}\newcommand*{\experiment}{\textbackslash\texttt{experiment}}
%\newcommand*{\typesection}{\textbackslash\texttt{section}}\newcommand*{\typechapter}{\textbackslash\texttt{chapter}}
% If you have more (or simply other\footnote{With other, I mean other
% names for the same concept -- e.g. my labbook.cls uses \labday\
% instead of \typechapter\ and \experiment\ instead of \typesection.
% Different concepts, as e.g. in alphanum.sty, won't work. But anyway,
% you'll only want to use one of both.}) sectioning macros, you have
% to tell alnumsec about their names and whether the first is on
% \LaTeX{}s level 0 (like chapter) or 1 (like section). This is done
% with the macro |\alnumsectionlevels| - here is what the package uses
% for the article class:
% \begin{verbatim}
% \alnumsectionlevels{1}{section,subsection,subsubsection,paragraph,subparagraph}
% \end{verbatim}
%
% If you use this macro, you have to do it \emph{before}
% |\alnumsecstyle|!\smallskip
%
% alnumsec.sty assumes that the number is typeset using |\the<name>| for
% section level |<name>|. This will always be the case if the macro has
% been defined using the \LaTeX\ macro designed for this,
% |\@startsection|.
%
%
% \section{Bugs and Limitations}
% \label{sec:bugs-limitations}
%
% Currently I am not aware of any real bugs, but one could imagine a lot
% of more features. However, since I wrote this package for somebody
% else's needs and don't use it myself, I need input from users to be
% able to improve it.

%
% |alnumsec@level| is the dynamic counter used while browsing through
% the levels. |fk@secdepth| is the number of sectioning levels for
% which names are known and thus numbers can be assigned. |fk@secstart|
% will be the starting value for every use of |alnumsec@level|, i.e. it
% will be 0 if |\chapter|\footnote{or some other macro on the level 0}
% is defined and 1 otherwise. |fk@changelevel| is the level from which
% the alternative separators for lower levels will be used. It is
% initially set very high so that lower level separators won't be used
% unless this counter is changed, using the following command:
%
% \begin{macrocode}
\def\otherseparators#1{%
\setcounter{fk@changelevel}{#1}
}
% \end{macrocode}
%
% |\alnumsectionlevels| is the command for users that have more or
% different than the usual section names. The main work is done by
% |\fk@countlevels|, after that |fk@secdepth| is set to the number of
% known levels.

}
% \end{macrocode}
%
% |\fk@countlevels| goes through the comma separated list of level names
% until it encounters the relax that has been put at the end by
% |\alnumsectionlevels|. For each level, it puts this name into a
% "numbered" name, e.g. |\fk@levelname1|, and increases the counter.

% |\fk@scanstyle| increments |alnumsec@level| \emph{after} it has parsed
% each letter, so after the last letter it is incremented once more.
% Then |\fk@assignstyle| is called which actually defines |\thesection|
