# Rake tasks for managing git plugins with submodules.
#
# These tasks aim to make life simpler by automating all the boring work.
# What you get:
#   - complete git integration (all you need to know is install, uninstall and update)
#   - complete github integration (only use author name + plugin name)
#   - rails plugin hooks (install.rb/uninstall.rb) are taken care of 
#
# Available commands:
#

# Install
# 
# Move this file into config/preinitializer.rb
#
# Usage

# This line:
#   config.github_gem "mislav-will_paginate" 
# is equivalent to this line:
#   config.gem "mislav-will_paginate", :lib => "will_paginate", :source => "http://gem.github.com"
