% \begin{macro}{\footnote}
% \verb"\footnote" is not going to be the standard \LaTeX\ footnote.  
% So store the standard version.  Then restore the standard \verb"\footnote"
% when inside \verb"minipage" environment.
%
% Finally, make the command \verb"\footnote" into the reledmac two-column command.
%
%    \begin{macrocode}
\let\originalfootnote=\footnote % store this for use in minipages
\def\@minipagerestore{\let\footnote\originalfootnote
    \let\var\originalfootnote} % restore standard 
% \footnote inside minipages and miniedition environment, and 
% create the shorthand \verb|\variant|
% Now change \verb"\footnote" to the reledmac version:
\let\footnote=\footnoteA
