# 1) Select the proper EXDIR (path), MANDIR, MANEXT, LIBDIR, SIGVOID,
#	REGEX, DFLT_PAGER, and FMOD. Most of the other things aren't
#	normally changed (see the comments with each)
# 2) Select the proper machine/compiler/OS section of code
#	for MS-DOS look for the pattern 'MS-DOS'
# 3) make install
# 4) If you have the command 'file' that uses /etc/magic add the line:
#	38	string		Spreadsheet	sc file
