I am one of the minor Xastir developers. My first contribution was a trivial map caching algorithm that worked with the Online Tigermaps. I have since added minor bits of functionality and scripts, and have most recently been working on filling out some of the gaps in the documentation by updating this Wiki.
I encourage Xastir users to help out with the documentation process here. If you have questions, Ask! If you have any notes to contribute, PLEASE DO!
