-You can't use this module to test code given by the C<-e> command-line switch.
-
 Perl 5.8 is notorious for leaking like there's no tomorrow, so the suppressions are very likely not to be very accurate on it. Anyhow, results will most likely be better if your perl is built with debugging enabled. Using the latest C<valgrind> available will also help.
 
 This module is not really secure. It's definitely not taint safe. That shouldn't be a problem for test files.
