  # When developing a gem with a command, you normally use `bundle exec bin/command-name`
  # to run your app. At install-time, RubyGems will make sure lib, etc. are in the load path,
  # so that you can run the command directly.
  #
  # However, I don't like using 'bundle exec'. It is slow, and limits which directory you can
  # run in. So, instead, we fall back to some path manipulation hackery.
  #
  # This allows you to run the command directly while developing the gem, and also lets you
  # run from anywhere (I like to link 'bin/leap' to /usr/local/bin/leap).
