Projects/Documentation Tasks

This is an early stage project for MIT Kerberos. It is being fleshed out by its proponents. Feel free to help flesh out the details of this project. After the project is ready, it will be presented for review and approval.

Purpose

To keep track of the various tasks that need to be documented such as function documentation, administration, troubleshooting etc.
