14# a typical strategy to use this:
15# compile a NetBSD divremtest binary, an OSF/1 divremtest binary, and an
16# OSF/1 mktestcases binary. You then run mktestecases | divremtest -g
17# on an OSF/1 machine, and pipe the output to an rsh to a NetBSD machine
18# which then runs divremtest. You can test an infinite number of random
19# values that way; I like to put a 'dd' in, so I can see how much I've done.
