description \
	a Mac 128K, Mac 512K, Mac 512KE, Mac Plus and Mac SE emulator

long_description \
	Mini vMac is a Macintosh emulator. It emulates the earliest Macs, \
	from the original Mac 128K (built 1984-85) to the Mac SE (1987-1990). \
	The default is to emulate a Mac Plus (1986-1990)\; this is also \
	the best-tested and therefore recommended emulation.
