	Merb borrows quite a bit of conventions from rails but also has it's  
own interesting features. One of the main goals of the project is to  
have a small, tight easily extensible core that is fast and has clean  
explicit entry points for plugins and customizations. It's a lot more  
modular than rails is as far officially supporting 3 different ORM  
backends, activerecord, sequel and datamapper, supporting test/unit or  
rspec for testing.

	Merb does not use the stdlib cgi.rb, it implements all its own  
multipart parsing and is much faster at it. In fact merb is much  
faster then rails in general:

	Hhere is a pdf called Why Merb? It covers a lot of the points where  
merb is different from rails.
