Gemmy gem

This is a general purpose gem which adds functionality to the ruby language and defines some system tasks, such as generating a gem.

It is on RubyGems. Because there is an existing gem named gemmy, the name passed to gem install is gemmyrb. But require 'gemmy' is still used.

RubyGems hosts the YARD documentation at http://www.rubydoc.info/gems/gemmyrb, but it's only updated when I push a new gem version. So the version here on Github's master branch might contain undocumented functionality. I'll try to keep the RubyGems version up-to-date though.

YARD is not the best for a birds-eye overview. For that, see the following documents:

• Loading the gem's code in different scopes
  • examples/01_using_as_refinement.rb
  • examples/02_using_globally.rb
• List of methods intended for general Ruby use
  • examples/03_ruby_extensions_list.rb
• Shell commands and other one-off processes
  • examples/04_shell_commands.rb
