-% \section{Backwards compatibility}
-%
-% In v0.1 of this package, the \cmd\NewEnvironment\ macro was
-% used instead (described below). There were a number of limitations with the different
-% approach that it used, the main ones being:
-% \begin{itemize}
-% \item Option processing occured with \emph{every} instance of |#1|
-% (which represented the environment body),
-% \item Environment options were only available \emph{after} the first instance of |#1|.
-% \end{itemize}
-% Please, please, don't use \cmd\NewEnvironment.
-%
-% The code for this syntax is still loaded by this package for
-% backwards compatibility, but in the next major release it will
-% be moved to a conditional package option. Eventually, I'll
-% probably delete it from the package altogether.
-%
-% \subsection{Previous code documentation}
-%
-% Just in case you need the documentation for the old syntax, here it is:
-% \codeline \cmd\NewEnvironment\marg{name}\marg{macro code} ,\\
-% where \marg{macro code} has argument |#1| as everything inside the environment.
-%
-% Now, this kind of environment definition makes collecting arguments a little cumbersome. Arguments are defined with a separate macro that `gobbles up' the arguments inside the environment before the body is passed to \marg{macro code}.
-% \codeline \cmd\EnvironArgs\marg{name}\oarg{N.\ args}\oarg{opt. arg.}\marg{arg. macro code} \\
-% This follows the same syntax of defining a macro with several arguments and a possible optional argument at the beginning. Here's an example:
-% \begin{example}{}
-% \NewEnvironment{test}{(#1)\tmp}
-% \EnvironArgs{test}[2][before]{\def\tmp{\par---#1/#2---}}
-% \begin{test}{after}
-% par
-%
-% graf
-% \end{test}
-% \end{example}
-%
-% I've tried to ensure that whitespace is ignored at the appropriate places; without this additional code, there would be a space before `par' and after `graf' in the examples above.
-%
-% Environments created with \cmd\NewEnvironment\ are ended by the command \cmd\ignorespacesafterend, which means that if they're used in a paragraph then the |\end{...}| command will gobble space after it. (If the environment is a paragraph on its own, there will be no difference.)
