Hi! I started to gemify it.
If you add gem 'yUMLmeRails', :git => 'git://github.com/tute/yUMLmeRails.git' to your Gemfile and then run bundle install, it adds the new rake tasks, and works as intended with Rails 3 apps.
I think we could also add railroad as a requirement.
Ruby 1.9 Rails 3 upgrade. Trailing white space trimming.
Adds rake task with Railtie.
Removes shoes dependecy for showing generated file.
Generates vertical diagrams.
Removes unused type of diagrams.
Switched to railroady.
