76 The Linux pcp-ipcs utility is not fully compatible to the POSIX pcp-
77 ipcs utility. The Linux version does not support the POSIX -a, -b and
78 -o options, but does support the -l and -u options not defined by
79 POSIX. A portable application shall not use the -a, -b, -o, -l, and -u
80 options.
