This module helps run test scripts in IDEs like Komodo.

When running test scripts in an IDE i have to set up a project file
defining the dist dir to run tests in and a lib dir to load additional
modules from. Often I didn't feel like doing that, especially when i only
wanted to do a small patch to a dist. In those cases i added a BEGIN block
to mangle the environment for me.

This module basically is that BEGIN block. It automatically moves up one
directory when it cannot see the test script in "t/$scriptname" and
includes 'lib' in @INC when there's no blib present. That way the test ends
up with almost the same environment it'd get from EUMM/prove/etc., even
when it's actually run inside the t/ directory.
