-# How it works:
-# 
-#   * Maintains a list of subversion repositories that are assumed to have
-#     a plugin directory structure. Manage them with the (source, unsource,
-#     and sources commands)
-#     
-#   * The discover command scrapes the following page for things that
-#     look like subversion repositories with plugins:
-#     http://wiki.rubyonrails.org/rails/pages/Plugins
-# 
-#   * Unless you specify that you want to use svn, script/plugin uses plain old
-#     HTTP for downloads.  The following bullets are true if you specify
-#     that you want to use svn.
-#
-#   * If `vendor/plugins` is under subversion control, the script will
-#     modify the svn:externals property and perform an update. You can
-#     use normal subversion commands to keep the plugins up to date.
-# 
-#   * Or, if `vendor/plugins` is not under subversion control, the
-#     plugin is pulled via `svn checkout` or `svn export` but looks
-#     exactly the same.
