%%%
\setlength{\textfloatsep}{0.7in}
\raggedbottom

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

%%%
%%% 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.
\newcounter{equationsave} % used in trick with equation number
\newenvironment{examples}% % define "example" environment
{%
\begin{list}{(\theequation)}%
{%
\setcounter{equationsave}{\arabic{equation}}%
\usecounter{equation}% % sets it to zero, unwantedly
\setcounter{equation}{\arabic{equationsave}}% % restores previous value
\setlength{\listparindent}{0pt}%
\def\makelabel##1{##1\hfil}% % put labels flushleft in space available
}%
\raggedright}% % text is flushleft, not justified

%%%
%%% 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)}
