%
%  \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!
