% \section{Introduction}
% This package is an add-on to the |MathTime| style, a style to
% provide TeX support for the use of the MathTime\texttrademark\
% commercially distributed by Y\&Y, Inc.
%
% The style file for MathTime has hard-wired uppercase Greek letters,
% they are upright and only upright, though the fonts come with
% italic letters as well for each and every weight. This package
% provides a switch to choose between both kinds of Greek uppercase
% letters.
%
% \DescribeMacro{\uprightupcasegreek} With the command
% |\uprightupcasegreek| you turn to upright letters, with
% \DescribeMacro{\italicupcasegreek} |\italicupcasegreek| you turn to
% italics.
%
% \StopEventually {}
%
% \section{Realization}
% The whole stuff is realized by tweaking NFSS2, since Greek
% characters are distributed rather madly in the fonts. In fact,
% after a no-op option processing event
%
% \begin{macrocode}
\ProcessOptions\relax
% \end{macrocode}
%
% and the explicit care, that we do not tweak the original math font
% setup,
%
% \begin{macrocode}
\RequirePackage{mathtime}
% \end{macrocode}
%
% we in fact adapt the core \LaTeX2e\ routines for command-character
% mapping |\DeclareMathSymbol| and |\set@mathsymbol| by throwing away
% all warning, other operators or |\@onlypreamble|-stuff.
%
% \begin{macro}{\mtg@realloc}
% The macro |\mtg@realloc| turns the decimal digit into a
% hexadecimal one (why isn't there a central routine for more than
% one digit?) and calls |\mtg@re@lloc|,
%
% \begin{macrocode}
\def\mtg@realloc#1#2{%
\begingroup
\count\z@=#2\relax
\count\tw@\count\z@
\divide\count\z@\sixt@@n
\count@\count\z@
\multiply\count@\sixt@@n
\advance\count\tw@-\count@
\expandafter\mtg@re@lloc
#1{\hexnumber@{\count\z@}\hexnumber@{\count\tw@}}%
\endgroup}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\@mtg@re@lloc}
% then overwrites the |\mathchardef|inition for a single letter.
%
% \begin{macrocode}
\def\mtg@re@lloc#1#2{\global\mathchardef#1="01#2\relax }
% \end{macrocode}
%\end{macro}
%
% The two switches take the character codes and plug them into the
% appropriate letter commands, e basta cos\`\i!
