License?

[eas]

Thanks for developing and releasing this library.

I'm reviewing license terms for some of the packages we are
considering for our project, and it isn't clear to me what license
this is released under. The Rubyforge page lists the ruby license,
but I don't find any reference to this in the actual files on
github.

Thanks!

I added some text to the README.
