# I have seen a bug in which renaming a directory (actually copying it
# using cp -a) caused fac to believe there were two rules that would
# produce the same file, because the .fac.tum files had the old
# absolute path name.  I have not yet been able to reproduce this bug
# here.  :( I'm leaving this test in case I see the bug again, so I
# can easily slot in an improvement here.
