trac

Automatic Benefits:

Your clients learn to use an environment similar to the site you are building for them, rather than the different markup syntax and behaviors of trac or other system.

Features:

• URL fields for bug reports which would be able to replace (or generate) the base URL with a defined set of URLs for development, stage, or production sites in use.
• Time tracking?

Resources:

• How to package a profile on drupal.org

Run trac-admin commands on the server hosting the trac sites. In our Debian server setup at least, individual projects are in the /srv/trac/ directory, and every trac-admin command should be followed by the path to the project you care about.

For more information than man will give you, use:

trac-admin help

To make a user an admin (I believe this will automatically create a new user if it has to) --

trac-admin /srv/trac/example permission add username TRAC_ADMIN
