For those of you who haven't heard of trac, its an extensible, and for the most part very sophisticated project management and bug tracking tool written in python and released to the comunity. Each company has its own requirements, and this can result in the need to modify trac for your own requirements, and trac has a very capable plugin system, however in keeping with many brilliant open source projects, it has poor documentation. You could flame me about the documentation issue, but i will admit that there is some very well documented open source documentation, however Trac has a very poor standard of documentation, when compared with the stellar product that it is. Accidentally when looking at building egg files, i came across the tutorial that explained how the entire framework for plugins was developed, i had reverse engineered most of what i had needed, but it was still lacking the real understanding. Egg Cooking Tutorial - A good introduction to writing plugins, it should be included on the tracdev documentation
