Usage:	$APPNAME [options] [--] [install-plist [uninstall-plist]] [make opts]
Options:
	-h,--help	Show this help.
	-V,--version	Show version number.
	-x,--debug	Turn on shell command tracing.
	-m,--man <file>	Write Makefile man page entries here.
	-p,--prefix <dir>
			Installs to here [/usr/local].
	-v.--var	Variable containing top level dir [DESTDIR].
	--		Stop option processing.

NOTES:
1. If neither file is specified, writes the plist to stdout.
2. If only an install-plist file is specified, writes the uninstall part
   of the plist there, too.
3. If -m/--man is not specified, does not write any info about man pages.
