%
% \subsection{Language tools}
%
% Languages are referenced by their {\bf babel} names. 
%
% \subsubsection{Define language}
%
% Usage example: |\definelanguage{welsh}{cy}{cym}{cymraeg}|
% 
% This will define
% \begin{itemize}
% \item three internal commands: |\@welshdec|, |\@welshcmd| and |\@welshenv|,
% \item a declaration |\cy| which maps to |\@welshdec|,
% \item a command |\cym{...}| which maps to |\@welshcmd{...}|,
% \item an environment |`cymraeg'| which maps to environment |`@welshenv'|.
% \item an environment |`welsh'| which also maps to environment |`@welshenv'|.
% \end{itemize}
%
% \hrule
% {\bf Important}. Language environments are implemented as |comment| environments, which allows us to discard their contents when required. The |comment| package documentation states that
% \begin{quote}
% ``... all text included between |\begin{comment}| and |\end{comment}| is discarded. The opening and closing commands should appear on a line of their own. No starting spaces, nothing after it.''
% \end{quote}
%
% Failure to ensure this can produce some very confusing errors! This also applies to the |proof| and |answer| environments defined below.\vspace{0.5ex}

}
\newcommand{\definelanguage}[1]{\multinotes@definelanguage{#1}}
%    \end{macrocode}
%
% \subsubsection{Include language}
%
% Usage example: |\includelanguage{welsh}|
%
% When a language is included it is assigned a sequential number, which specifies its column number in |paracol| environments. %The |\switchcolumn| command is only defined within \verb+paracol+ environments, and therefore provides a criterion to decide whether column switching is required.

%    \end{macrocode}
%
% \subsubsection{Parallel typesetting}
%
% The |multicols| environment is based entirely on the |paracol| environment from the package of the same name. The number of columns required is obtained from the |numlangs| counter value. Any option commands for |paracol| such as |\columnsep|, |\columnseprule| or |\localcounter| can be used directly.
