%\maketitle
%
% This package defines the |\resmes| command in order to print measure restriction symbol. For example in mathmode
% \begin{verbatim}
%  \mu\resmes A
% \end{verbatim}
% expands as
% \[
%  \mu\resmes A
% \]
%
% This package works also in inline math mode ($\mu\resmes A$) and in subscript/superscript emvironments ($a^{\mu\resmes A}, b_{c^{\mu\resmes A}}$).
