SM Rails Extension
The Rails extension is used to manage all aspects of a Ruby/Rails application project deployment as a user.
For example, if the project name is 'todo' then for deployment you would typically create an 'todo' user on the server with home directory of /home/todo.
An detailed walkthrough of using SM Rails extension in conjunction with other extensions (below) to manage an application deployment may be found on the RVM website at
