# To do:
#   * put stuff into functions, maybe
#   * launchpad apparently works with word-wrapped SSH keys, OpenSSH doesn't, deal with that somehow
#   * tests?  how do you test something like this...?
#   * error reporting
#   * verify that the user exists in launchpad before creating them
#   * get GECOS fields from some launchpad structured thing (does launchpad export that?)
