"m4expand" will run the m4 macro preprocessor on the named input file.
The output of m4 is written to the standard output (your terminal) so
you can see the expansion of all macros and include files. This enables
you to see the file that will be created by "m4orch"

Usage:
	m4expand filename

Orchestra or score files can be run through "m4expand." The variant
"m4expandsc" is useful for score files if you want to see expansion
of the instrument name into its resulting number.
