# Initialize or shutdown a PCMCIA memory device
#
# The first argument should be either 'start' or 'stop'.  The second
# argument is the base name for the device.  When starting a device,
# there should be two additional arguments, the major and minor device
# numbers.
#
# Three devices will be created:
#
#	/dev/{name}a	- character device, attribute memory
#	/dev/{name}b	- block device, common memory
#	/dev/{name}c	- character device, common memory
