Adam Vandenberg b4ac7d994a Extract base class for Amazon Web Services.
Many Amazon Web Service tool bundles have similar setup steps and caveats,
so extract a base class and use that for other formulae.

Before you can use these tools you must export some variables to your $SHELL
and download your X.509 certificate and private key from Amazon Web Services.
Your certificate and private key are available at:
http://aws-portal.amazon.com/gp/aws/developer/account/index.html?action=access-key
Download two ".pem" files, one starting with `pk-`, and one starting with `cert-`.
You need to put both into a folder in your home directory, `~/.ec2`.
To export the needed variables, add them to your dotfiles.
* On Bash, add them to `~/.bash_profile`.
* On Zsh, add them to `~/.zprofile` instead.
export JAVA_HOME="/System/Library/Frameworks/JavaVM.framework/Home"
export EC2_PRIVATE_KEY="$(/bin/ls $HOME/.ec2/pk-*.pem)"
export EC2_CERT="$(/bin/ls $HOME/.ec2/cert-*.pem)"
export #{var_name}="#{var_value}"
