This section describes the content to be delivered at each stage of the project (one milestone and a final rollout). Each deliverable is a superset of the previous one - it MUST include all of the materials from the previous deliverable as well as the new materials. Rollout MAY also contain updates to the previous deliverable. If updates to a past deliverable are included, the README.TXT file MUST indicate which components (including code, documentation, tests, etc.) have been modified. For the deadlines of these stages, please refer to Section 7.
