When using this module in a test script, it goes through all the modules in your distribution, checks their POD, checks that they compile ok and checks that they all define the same $VERSION.
It defines its own testing plan, so you can't use it in conjunction with other Test::* modules in the same file. Therefore it's recommended that you just create a one-line test script as shown above.
