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.
