This module is intended as a tool for module authors who would like to easily test that a module release will not break dependencies. This is particularly useful for module authors (like myself) who have modules which are a dependency of many other modules. Internally, this module will download dependencies from CPAN and run their tests. If those dependencies in turn have unsatisfied dependencies, they are installed into a temporary directory. These second-level (and third-, etc) dependencies are not tested.
