So you've cloned somebody's repo from github, but now you want to fork it and contribute back. Never fear!

Technically, when you fork "origin" should be your fork and "upstream" should be the project you forked; however, if you're willing to break this convention then it's easy.

* Off the top of my head *

1. Fork their repo on Github
2. In your local, add a new remote to your fork; then fetch it, and push your changes up to it

    git remote add my-fork git@github...my-fork.git

# A simple function to return a signed, expiring url for Amazon Cloudfront. 
# As it's relatively difficult to figure out exactly what is required, I've posted my working code here.

# This will require openssl, digest/sha1, base64 and maybe other libraries. 
# In my rails app, all of these are already loaded so I'm not sure of the exact dependencies.

module CloudFront
  def get_signed_expiring_url(path, expires_in, private_key_filename, key_pair_id)
