\def\gbVersion{4e}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Version 4export (= v. 4 minus the compatibility code)
% Based on hpk's gb.sty, revised for GM syllabus by ct,
% and incorporating macros adapted from J.Frampton, M. van der Goot en M.
% Covington. Full documentation in gb4e-doc.tex. Bug-reports
% and suggestions for improvements, other used features, please!
%
% The package gb4e may be distributed under the conditions of the LaTeX Project
% Public License (LPPL). See the README file for more details.
%
% Notes:
%
% Various styles for X-bar levels; can be changed, but note that {picture}
% environements (e.g. trees) will then come out wrong and have to be
% fixed
%
% This file allows _ and ^ to be used in ordinary text, hence must be
% loaded AFTER any file that uses them in their TeX meaning. Hence
% cgloss(n).sty is loaded early in this file. This feature is known to
% cause some problems with other packages, but is maintained for backward
% compatibility. If you have problems, you can try disabling it by
% placing the command \noautomath immediately after loading the gb4e package.
% [Added 2009/12/28]
% CHANGE LOG
%
% 2010/7/2
% - Fixed bug (introduced in previous changes) that discarded spaces
% after sub/superscripts outside math mode.
%
% 2010/01/03 [unreleased]
% - Removed stray \bf
% - Removed leftover old definition of ^, _
%
% 2009/12/28
% - Added README.txt with LPPL license statement.
% - Updated sub- and superscripts outside of math mode. They now
% combine properly, and the feature can be turned off with \noautomath
% (and back on with \automath).
% - Removed references to \rm, for compatibility with memoir.cls
% - \@footnotetext is no longer modified destructively; compatible with
% other packages that modify it.
% - \eachwordone etc. can now be defined to font commands that take
% arguments (e.g., to \textit).

%%%%%%%%%%%%%%%%%%%%%%%%
% Format of examples: %
%%%%%%%%%%%%%%%%%%%%%%%%
% \begin{exe} or \exbegin
% <examples> (arab.)
% \begin{xlist} or \xlist
% <subexamples> (1st embedding, alph.)
% \begin{xlisti} or \xlisti
% <subsubexamples> (2st embedding, rom.)
% \end{xlisti} or \endxlisti
% <more examples>
% \end{xlist} or \endxlist
% <still more examples>
% \end{exe} or \exend
%
% Other sublist-styles: xlistA (Alph.), xlistI (Rom.), xlistn (arab)
%
% \ex (produces Number)
% \ex <sentence> (numbered example)
% \ex[jdgmt]{sentence} (numbered example with judgement)
%
% \exi{ident} (produces identifier)
% \exi{ident} <sentence> (example numbered with identifier)
% \exi{ident}[jdgmt]{sentence} (dito with judgement)
% (\exr, \exp and \sn are defined in terms of \exi)
%
% \exr{label} (produces cross-referenced Num.)
% \exr{label} <sentence> (cross-referenced example)
% \exr{label}[jdgmt]{sentence} (cross-referenced example with judgement)
%
% \exp{label} (same as
% \exp{label} <sentence> \exr but
% \exp{label}[jdgmt]{sentence} with prime)
%
% \sn <sentence> (unnumbered example)
% \sn[jdgmt]{sentence} (unnumbered example with judgement)
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% For my own laziness (HANDLE WITH CARE---this works only
% in boringly normal cases.... ):
%
% \ea works like \begin{exe}\ex or \begin{xlist}\ex,
% depending on context
% \z works like \end{exe} or \end{xlist}, dep on context
