    This is the pattern we match against. This is actually x.y.z... version format, that RubyGems 1.3.5 support. {@link http://github.com/jbarnette/rubygems/blob/REL_1_3_5/lib/rubygems/version.rb} and ://github.com/jbarnette/rubygems/blob/REL_1_3_6/lib/rubygems/version.rb

```
    Creates valid GEM version out of Maven2 version. Gem versions are "stricter" than Maven versions: they are in form of "x.y.z...". They have to start with integer, and be followed by a '.'. You can have as many like these you want, but Maven version like "1.0-alpha-2" is invalid Gem version. Hence, some trickery has to be applied.
