% This is adapted from the \diatop macro in wsuipa.sty, which was
% originally designed by Jean-Pierre Paillet.

                     \hbox to1\dimen0{\hss#2\hss}}}%

% Example of usage: \twoacc[\^|\={a}]
% Special cases:

\def\acm#1{\twoacc[\'|\={#1}]}   % acute over macron
\def\grm#1{\twoacc[\`|\={#1}]}   % grave over macron
\def\cim#1{\twoacc[\^|\={#1}]}   % circumflex over macron

%%% Example numbering
%%%

% Example numbering uses the same counter as LaTeX's equation numbering.
% Thus, you can use \label and \ref to refer to numbered examples in
% exactly the same way as with equations.

% \exampleno  increments the counter and gives you its current value.
%             You can use it anywhere to generate an example number.
%
%             For example, to display a sentence with a number at the
%             right margin, do this:
%
%             \begin{flushleft}
%             This is a sentence.  \hfill (\exampleno)
%             \end{flushleft}

\newcommand{\exampleno}{\refstepcounter{equation}\theequation}

%%%
%%% The 'example' environment
%%%

% example     is an environment for displaying a single numbered 
%             example, preceded by its number.  Example of use:
%
%             \begin{example}
%             This is an example.
%             \end{example}
%
%             This is actually a special case of 'examples' where
%             the first \item is automatically supplied.
%
%             To display sub-examples with numbers such as
%             (3)(a), (3)(b), etc., you can use 'itemize', thus:
%             \begin{example}
%              \begin{itemize}
%              \item[(a)] This is the first example.
%              \item[(b)] This is the second example.
%              \end{itemize}
%             \end{example}

\newenvironment{example}{\begin{examples}\item}{\end{examples}}

%%%
%%% The 'examples' environment
%%%

% examples    is an environment for displaying a series of examples
%             together, each with its own example number.  Usage:
%
%             \begin{examples}
%             \item This is the first example.
%             \item This is the second example.
%             \end{examples}
%
% Thanks to Darrel Hankerson of Auburn University, and numerous others
% across the net, for help with this macro.

%%% Sentences with word-by-word glosses
%%%

% See covingtn.tex for full documentation.  Some examples:
%
% Displayed sentence with gloss and translation:
%
%             \gll Dit is een Nederlands voorbeeld.
%                  This is a Dutch example.
%             \glt `This is an example in Dutch.'
%             \glend
%
% Same, using bracketing where words do not correspond one-to-one:
%
%             \gll Dit is een voorbeeldje     in het Nederlands.
%                  This is a {little example} in {}  Dutch.
%             \glt `This is a little example in Dutch.'
%             \glend
%
% Same, with example number added at right:
%
%             \gll Dit is een voorbeeldje     in het Nederlands.
%                  This is a {little example} in {}  Dutch.
%             \glt `This is a little example in Dutch.' \hfill (\exampleno)
%             \glend
%
% Same, with number but no (line reserved for) translation:
%
%             \gll Dit is een voorbeeldje     in het Nederlands.
%                  This is a {little example} in {}  Dutch.
%             \gln \hfill (\exampleno)
%             \glend
%
% If you want to align 3 lines rather than two, use \glll instead of \gll.
%
% Layout is critical between \gll (or \glll) and \glt (or \gln).
% After \glt, environment is essentially the same as 'flushleft'.

%%%
%%% Discourse representation structures
%%%

% \drs        typesets a DRS in box notation a la Kamp.
%             Arguments:
%             1. List of discourse variables joined by ~
%             2. List of conditions joined by \\
%
%             Example:   \drs{X}{donkey(X)\\green(X)}
%
%             Example:   \drs{~}{purple(X,Y)}
%
%             Example:   \drs{X}
%                            {named(X,`Pedro') \\
%                             \drs{Y}{donkey(Y)\\owns(X,Y)}~~
%                             {\large $\Rightarrow$}~
%                             \drs{~}{feeds(X,Y)}
%                            }

% \sdrs       like \drs but first argument is a sentence
%             to be displayed above the drs.
%
%             Example:   \sdrs{A donkey is green.}{X}{donkey(X)\\green(X)}

% \ifdrs      forms 2 DRSes joined with a big arrow.
%             Usually used for DRSes nested within another.
%
%             Example:   \ifdrs{X}{donkey(X)\\hungry(X)}
%                              {~}{feeds(Pedro,X)}

% \alifdrs    is like \ifdrs but shifted to the left so that an
%             embedded `if' structure will line up with ordinary
%             DRS conditions.

% \negdrs     forms a DRS preceded by the negation symbol.
%
%             Example:   \negdrs{X}{donkey(X)\\green(X)}

% Exercises, reference lists, and miscellany
%

% exercise    Environment for exercises, numbered by subsection.
%             Optional argument for describing the exercise
%             ("Project" or the like).

% \bx         Abbreviation for \begin{exercise}
% \ex         Abbreviation for \end{exercise}

% reflist     Environment for hanging-indented list
%             (suitable for LSA-style reference list).
%             Does NOT require \item before entries.

% \sentence   Displays its argument, flushleft, italicized.

% \either     Displays its arguments as alternatives between
%             large curly brackets.  Good for alternatives
%             within sentences or PS-rules.

\newtheorem{exercise}{Exercise}[subsection]

% Exercise numbering resets to 0 not only at the start of
% a subsection, but also at the start of a section or chapter
% even if it is not divided into subsections.
