Re^3: What are the files in a CPAN distribution?by Tux (Abbot)
|on Dec 19, 2012 at 19:47 UTC||Need Help??|
Most modules are no in some sort of reproducable VCS: svn or git, and most have some sort of preferred way of contributions (github).
If people want to work on a module/distribution, a git clone or svn copy will get you *all* files, including those that - I agree with tobyink here - are listed in .gitignore and MANIFEST.SKIP. I hope at least that the authors are sane enough to have these two in the repository anyway.
Enjoy, Have FUN! H.Merijn
