Internal Program Version: Test::FailWarnings  0.008.5.42.0

This module hooks 'SIG{__WARN__}' and converts warnings to the Test::More
manpage 'fail()' calls. It is designed to be used with 'done_testing', when
you don't need to know the test count in advance.

Just as with the Test::NoWarnings manpage, this does not catch warnings if
other things localize 'SIG{__WARN__}', as this is designed to catch
_unhandled_ warnings.
