+# The steps needed to register new CLI commands from outside

+# 1. Related command files need to be copied to the artoo install commands.
+# 2. We do this with a rake task that is triggered when the gem is installed
+#    (see .gemspec file and look for extensions, ext/Rakefile), in the Rakefile
+#    we defined a new default class that makes use of an artoo helper class/method
+#    Artoo::Commands::Install helper method '.command'; see ext/Rakefile for details.
+# 3. Finally in our main command file (THIS FILE) we open the artoo CLI::Root class to register
+#    the new commands.
