| Subject: | Check PREREQ_PM for unnessecary modules |
Test::Prereq ensures that all of the modules the tested distribution
needs shows up in the PREREQ_PM argument to WriteMakefile, but I would
like it to also report things that show up in PREREQ_PM but are not used.
There is one major problem with this though: The module might dynamically
use another module in a way that Test::Prereq cannot know about it, so
any solution needs a way to specify that the entry is correct. The prereq_ok() function already has an optional third argument to do this sort of thing.
