  Hey, you found the source code!

  That is a sign you hopefully know better than to blindly run unknown commands
  from the internet and/or are a curious person. We like you already.

  What this command will actually do, is set you up with a free "shell" account
  on one of our servers, that you can use as you see fit. It will also set you
  up with email, IRC, and other things on your shell, so you can keep in touch
  and learn/make awesome things with us.

  Don't trust us? Good! You probably don't know us (yet) so you shouldn't.

  To help address this we GPG sign this shell-setup script so you can verify
  it has not been changed by a third party before you run it by doing:

  > gpg --verify <(curl https://hashbang.sh)

  The safest method of running a script from a source you don't trust is to:

  Download locally over SSL
  > curl https://hashbang.sh >> hashbang.sh

  Verify integrty with GPG (If available)
  > gpg --recv-keys 0xD2C4C74D8FAA96F5
  > gpg --verify hashbang.sh

  Inspect source code
  > less hashbang.sh

  Run
  > chmod +x hashbang.sh
  > ./hashbang.sh

  As an advanced alternative you can bypass using this script and hit our user
  provisioning API directly with an SSH Public Key and desired username:

  > curl -d '{"user":"someuser","key":"'"$(cat ~/.ssh/id_rsa.pub)"'"}' -H 'Content-Type: application/json' https://hashbang.sh/user/create

  We look forward to seeing you on the other side.
