Together with Tiago Pinto I’ve completed a TarPipe API for Ruby.

tarpipe is a publishing mediation and distribution platform that simplifies regular upload activities

The gem is available here and the sources are on github. It is my first released gem so feel free to send some tips and suggestions.

TarPipe is currently evolving very fast so me and Tiago will make sure our library stays up to date. Have fun doing your uploads!
