# Gem::CommandManager instance, like this:
#
#   # file rubygems_plugin.rb
#   require 'rubygems/command_manager'
#
#   Gem::CommandManager.instance.register_command :edit
#
# You should put the implementation of your command in rubygems/commands.
#
#   # file rubygems/commands/edit_command.rb
#   class Gem::Commands::EditCommand < Gem::Command
#     # ...
#   end
#
# See Gem::Command for instructions on writing gem commands.
