This is a dummy file to help compile multiple versions of the same source file.
The commands are very simple, they can be improved in a variety of ways.

\def\basename{mc-dbu-ctrld} % base name of target file
\def\altbasename{mc-dbu}    % base name of output file
% define a simple \forVersion command, convert letter to upper case
\def\forVersion#1{\uppercase{\edef\selVersion{#1}}}

% select the version letter (upper or lower case)
\forVersion{a}
% define a suffix that follows \altbasename, redefine as desired
\edef\altsuffix{%
  \if\selVersion Asec01\else
  \if\selVersion Bsec02\else
  \if\selVersion Csec03\else
  \if\selVersion Dsec04\fi\fi\fi\fi}
