Does more or less the same thing as App-Pmhack, albeit better. Now I don't know which one was there first but one of the authors should synchronize their efforts.
I am surprised by the fact that App-moduleshere contains nothing and the script contains the code. Most of the App::* modules contain code and the scripts almost nothing with the hope that someone will reuse the module somehow.
I also believe that it would be nice if the tools manipulating modules all started with 'pm' as the tools in search.cpan.org/~mlfisher/pmtools-1.10/. Maybe this should even be part of the pmtools module.
