Setups up repos in `./gems` from the root of a Rails project as local gems. This makes framework development much easier.

Rakefile

# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.

require_relative "config/application"

Rails.application.load_tasks

task :gems do
  Dir["gems/**"].each do |path|
    sh "bundle config local.#{File.basename(path)} #{path}"
