+%%% Example numbering
+%%%
+
+% Example numbering uses the same counter as LaTeX's equation numbering
+% by default.
+% Thus, you can use \label and \ref to refer to numbered examples in
+% exactly the same way as with equations.
+% As of v. 2.2, it is also possible to use an own counter and thus separate
+% equations from linguistic examples.
+
+% \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}

+% 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}

+%%% Sentences with word-by-word glosses
+%%%
+
+% See covington.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'.

+% \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)}
+
+% 2019-06-21 (v. 2.3): Do not define the macros if already defined.
+% This allows to use covington with the drs package.

+% exercise Environment for exercises, numbered by subsection.
+% Optional argument for describing the exercise
+% ("Project" or the like).
+%
+% New in 1.1 (2016-07-06):
+% We provide a covexercise environment and only (re)define
+% example if it does not yet exist or if redefinition is
+% forced by the "force" option. This prevents clashes
+% with packages/classes that roll their own exercise environment.
+
+% \bx Abbreviation for \begin{covexercise}
+% \ex Abbreviation for \end{covexercise}
+
+% 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.
+
