=======================================================================

The macros  \example  and  \fullExample  are designed to let the
music appear side by side with some verbatim code.

\fullExample{basename} takes the input from file  basename.tex  and
  puts the source from file  basename.mtx  next to it.  The right-hand
  minipage is centered because the source is expected to be taller than 
  the music.

\example{basename} takes the input from file  basename.tex  and
  puts the source from file  basename.mtb  next to it.  In the
  case of the M-Tx manual,  basename.mtb  is part of  basename,mtx,
  but of course one could put anything in the file.  The right-hand
  minipage is bottom=aligned ed because the source is expected to be 
  not taller than the music.
 
There are some small differences in dimensions between the two macros,
which are intended to make them look just right when used together.
