"""Screen scrapes jira.mit.edu. Supposedly. Doesn't actually work yet.

You need to have a personal certificate named cert.pem in this
directory to run this script. You also need the abovementioned scripts.
The zephyr bindings can be gotten from ebroder's GitHub repository
located: http://github.com/ebroder/python-zephyr/tree/master

SSL server CA authentication is disabled because we don't know how to
make curl stop complaining.

Current difficulty is we are causing a NullPointer exception on
(we think) touchstone's servers."""
