+  Action:
+
+    * usage  - Show this usage information
+    use      - Switch to using a specific ruby versio (new login shell)
+    info     - Show information for current ruby
+    gemdir   - Switch to gem directory for installation (new login shell)
+    srcdir   - Switch to src directory for the current ruby installation
+    gemdup   - Clone source implementation version gems to currently used version
+    install  - Install a ruby version, default is from source
+    debug    - Emit environment and configuration information for debugging
+
+  Implementation:
+
+    * ruby   - MRI/YARV Ruby (The Standard), defaults to 1.8.6
+    jruby    - jRuby
+    ree      - Ruby Enterprise Edition
+    rubinius - Rubinius (NIY)
+    default  - Resets to the default system ruby
+    all      - Used with install, installs all latest known versions
+  
+  Options: 
+
+    -v|--version    - Ruby Package Version, defaults to 'latest'
+    -l|--level      - Patch level for the specified Ruby version
+    -p|--prefix     - Package and source directory prefix, with trailing slash!
+                      Default is a users home directory and /usr/local/ for root
+    -c|--configure  - Options for source compile (default: --enable-shared)
+    -d|--debug      - Toggle debug mode on for extra messages (NIY)
+
+  Notes:
+
+    * Defaults above are denoted with a '*' prefix.
+    * rvm is intended to be run as an individual user (not root, yet)
+    * All ruby installation, configuration and source files are in ~/.rvm
+    * To manually reset to defaults: "rm -f ~/.rvm/current", then open new shell
+    * To preserve previous gem installations for a particular ruby version copy,
+      move, symlink or copy the old gem directory to (1.8 for 1.8.X): 
+      ~/.gem/$interpreter/$version
+
+  Examples:
+
+    $ gem install rvm       # Install the rvm gem
+    $ rvm-install           # Install rvm, adds source hooks to ~/.bash_profile
+    $ rvm install jruby     # Install jRuby, default 1.3.1
+    $ rvm use ruby -v 1.9.1 # Use Ruby 1.9, install first if not installed
+    $ rvm use -v 1.9        # Equivalent to above, because of defaults
+    $ rvm use default       # Use the system default (as if no rvm)
+
+  TODO: (in order)
+

+    * rvm gemdir default
+    * Debug level messages
+    * Rubinius (not in first revisions)
+    * Shell detection instead of simply assuming bash (not in first revisions)
