Version Handling

I want the version of my distribution is bumped automatically after each release, and automatically assigned version should be alpha (trial) one.

For example: if I released version "0.001", the version of the next release should be "0.001_01". When I release "0.001_01", the next should be "0.001_02", the next one — "0.001_03" and so on. When I decide it is time to non-trial release, I will reset the version to "0.002" manually, release it, and will have automatically bumped version "0.002_01".

This is implemented with two plugins: Hook:VersionProvider and Hook::AfterRelease. The first one reads version from external file VERSION which contains only version and nothing more (ok, trailing newline is allowed) — it simplifies implementation, because there is no need in parsing dist.ini file. The second plugin bumps the version after release with help from Perl::Version module, and writes bumped version back to the VERSION file.
