If you look into the directory you used to "nmake test" when installing PAR, you will
find a contrib directory somewhere underneath. Somewhere under there you will find a
file called automated_pp_test.pl that has a multitude of tests. I believe the small -a
and large -A tests are made for what you want to do. You will find tests entitled

sub pp_test_small_minus_a {
sub pp_test_large_minus_A {

I believe the explaination blocks in the file are up to date. You can also use
perl -d (debugger) and step through the actual test code.

Good luck.
