# We need to support the following options:
# NOTE: c, v, d, L, and M are needed by olc, and it cares what order
#  the output is in.
#  -c     : Processor type
#  -d     : display type 
#  -k     : select the kernel
#  -m     : override memory from /dev/kmem
#  -r     : disk drive type
#  -v     : more verbose -- about memory mainly
#  -A     : print Athena Release
#  -C     : print out compatible Athena System names
#  -E     : print out the version of the Base OS
#  -L     : version of athena from /etc/athena/version
#  -M     : physical memory
#  -N     : print out the name of the base OS
#  -P     : print out Athena System packs (from /srvd/.rvdinfo)
#  -S     : Print out the Athena System name
#  -q     : Print out "quickstation" or "not_quickstation" depending on if this
#           workstation is a quickstation or not
