# or the AFS install, which mishandles nonexistent args, or
# /usr/ucb/install on SVR4, which tries to use the nonexistent group
# `staff', or /sbin/install on IRIX which has incompatible command-line
# syntax.  Sigh.
#
#     On most BSDish systems install is in /usr/bin, not /usr/ucb
#     anyway.
# This turns out not to be true, so the mere pathname isn't an indication
# of whether the program works.  What we really need is a set of tests for
# the install program to see if it actually works in all the required ways.
