Would you mind to include License file in the coffee-script-source gem? I am packaging this gem for Fedora and the packaging guidelines  requires me to ask you. Thank you.
If I'm not mistaken, that gem hasn't been updated in a long time. Also, the license is available in the /License file. It should be MIT.
We push a new coffee-script-source gem with every official CoffeeScript release. https://rubygems.org/gems/coffee-script-source
The gem itself does not include the license file, but the bundled coffee-script.js does include this header:
* CoffeeScript Compiler v1.3.3
* Copyright 2011, Jeremy Ashkenas
* Released under the MIT License
Oh, interesting. What exactly does that gem provide?
coffee-script-source is extras/coffee-script.js packaged in a gem, with the same version number as the CoffeeScript release it packages, for use by the ruby-coffee-script gem.
ruby-coffee-script is released under the MIT license and lets you invoke the CoffeeScript compiler from Ruby.
@jashkenas has the final say on this, but IMO the coffee-script-source gem should be considered to have the same license as CoffeeScript itself.
Works for me.
There is no doubt about license. Just the independent LICENSE file should be included in the source package as required by the guidelines. But that is not showstopper, so nothing urgent.
