Question on Textmate Ruby on Rails bundle, what's the difference on HTML(Rails) mode and Ruby on Rails mode?

When developing Rails project using Textmate, there are some related modes. When pressing Win + Alt + Shift + r, you will get a list of modes:

• Ruby
• HTML (Rails)
• Ruby on Rails (RJS)
• Ruby on Rails
• SQL (Rails)

I want to know the difference between HTML (Rails) and Ruby on Rails. Anyone can expla开发者_StackOverflowin it please? Thanks.

Ruby on Rails mode is for working with controllers/models/helpers etc

HTML (Rails) mode is for dealing with views
