Project: DRAGON
===============

- Arrange an online demo of your compiler during Finals week (15min).

- Send a self-contained compressed tar source of your compiler by
  email. Your compiler must run on the ITL machines.

- Submit a hardcopy of your compiler documentation: design document,
  user manual, testing report, status report (limitations, caveats, or
  bugs), and a "dragon" haiku. Indicate clearly in your report an
  extra feature that is unique to your compiler.
