I think this will be sufficient. It seems like it should be settable at
'perl Makefile.PL' time, or via an environment variable, or at 'make diff'
time, overriding in that order. I'll give it a shot.
Setting it at 'perl Makefile.PL' time doesn't seem very important, but
for completion it seems like it should be possible.
