-% The \@ifmtarg command takes 3 arguments and \@ifnotmtarg takes 2 arguments.
-% \@ifnotmtarg is slightly more efficient when code is only required
-% for a non-empty argument.
-%
-% Example usages:
-% \newcommand{\isempty}{1]{%
-%   \@ifmtarg{#1}{\typeout{YES}}{\typeout{NO}}}
-%
-% \isempty{}    -> YES
-% \isempty{   } -> YES
-% \isempty{E}   -> NO
-% \isempty{ E } -> NO
-%
-% \newcommand{\isnotempty}[1]{%
-%    \@ifnotmtarg{#1}{\typeout{YES}}}
-%
-% \isnotempty{}    -> 
-% \isnotempty{   } -> 
-% \isnotempty{E}   -> YES
-% \isnotempty{ E } -> YES
-%
-%     In an Email to me on 13 March 2000, Donald Arseneau pointed out some
-% failings with my original definition of the \@ifmtarg command:
-% \newcommand{\@ifmtarg}[3]{%
-%   \edef\@mtarg{\zap@space#1 \@empty}%  
-%   \ifx\@empty\@mtarg\relax #2\else #3\fi}
-%
-% It works most of the time correctly but Donald showed that it can 
-% give unexpected results 
-% under conditions that I had not thought of. He suggested the coding 
-% that now appears in the package above for the \@ifmtarg and 
-% \@ifnotmtarg commands. For a discussion on detecting empty arguments 
-% see CTAN/info/aro-bend/answer.002
