-NAME
-     rails - creates a new Rails installation 
-
-SYNOPSIS
-     rails [full path]
-
-DESCRIPTION
-     This generator will create a suggested directory structure, lots of minor helper
-     files, and a default configuration for creating a new Rails application. Once the
-     generator is done, you're advised to look at the README in the root of the folder.
-     
-EXAMPLE
-     rails ~/Code/Ruby/weblog
-     
-     This will generate a new Rails installation in the ~/Code/Ruby/weblog folder.
