% \begin{exe} or \exbegin
% <examples>                           (arab.)

% Other sublist-styles: xlistA (Alph.), xlistI (Rom.), xlistn (arab)
%
% \ex                               (produces Number)

% For my own lazyness (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

%
% This is version 0.3 (informal release, Nov. 2003).
%
% Line up material a fixed distance from the right margin.  For annotating
% example sentences, usually with a short note in parentheses.
% May overflow to the left or right, or line up on the next line as necessary.
%
% \jambox[width]{text}	Align 'text' starting 'width' distance from the
%			right margin (default \the\jamwidth).
% \jam(something)	Align a note delimited by parentheses (which are
%			retained).  No optional argument.
% \jambox*{text}        Set \jamwidth to the width of 'text', then align it.
%			(\jamwidth stays set for the rest of the environment).
%
% Notes:
%
% Distance from the right margin can be set to an explicit amount, or to the
% width of some piece of text, as follows:
%
% \jamwidth=2in\relax      Or
% \settowidth\jamwidth {(``annotation'')}
%
% \jamwidth is locally scoped, so it can be set globally or inside an example
% environment.
%
% BUG: Not compatible with ragged-right mode.
%
% Incompatibilities: Not useful with the vanilla cgloss4e.sty, which ends
% glossed lines prematurely.
% I do have a suitably modified file, cgloss.sty. With it you can do the
% following:
% \gll To kimeno. \\
%      the text \\ \jambox{(Greek)}
% \trans `The text.'

% The penalty enables a break, taken only if the line cannot fit.
% The \hbox{} ensures the next line does not begin with \hfill, which would
% be discarded if initial.
% (\vadjust inserts an empty element at the beginning of the next line, so
% that COULD be used instead of \hbox{}).
% Algorithm adapted from The TeXBook.
%
% The closing \par could be a problem if there is a \parskip...
