Plugin Licenses

I am planning to release a Rails application under the MIT License that uses the resource_feeder and simply_helpful plugins from the Rails svn repository. Before I release, I'd like to clarify what the license is for these plugins (I couldn't see any license information for these plugins in svn).

I also took a look through the other plugins in svn. The following appear to be lacking license information:

acts_as_taggable continuous_builder localization resource_feeder restifarian simply_helpful simply_restful

Thanks,

Phil

Everything in the Rails repository is MIT unless otherwise stated.
