A suggestion to make it easier for your users in package management. Please sync the version numbers of your CPAN package with the version that your entry module uses. I have had to spend many wasted hours downloading and comparing version numbers across several modules just to determine what package release was being used.

If your package is a collection of tools, then perhaps a bare module named the same as the tool collection to contain this version number. (Just off the top of my head, I have no good ideas for this case)
