ExtUtils::Command::MM encapsulates code which would otherwise have to be done with large "one" liners. Any $(FOO) used in the examples are make variables, not Perl. =over 4 =item B<test_harness> test_harness($verbose, @test_libs); Runs the tests on @ARGV via Test::Harness passing through the $verbose flag.
