The Helipad Ruby interface is now available on GitHub in addition to its original home on RubyForge.
There’s no difference at all between the two, apart from the GitHub copy bearing my name, which is GitHub’s convention for preventing collision between identically-named gems. If you wish to install the gem from GitHub instead of RubyForge, you can do the following:
> gem sources -a http://gems.github.com > sudo gem install lonnon-Helipad
