Hello.

Some projects have different reference manuals/documentation (e.g.  
MySql 4.1, MySql 5.0, MySql 5.1,…) for each major release.

Is there an easy way to read the `Rails API` documentation (http://  
[api.rubyonrails.org/](http://api.rubyonrails.org/)) that is specific to version 2?

You can run `gem server` then browse to [http://localhost:8808/](http://localhost:8808/) to see  
the versions you have installed.
