[chirp_users] Would like to add to project.

I believe I can add additional radio compatibilities to this project. I have been tinkering with radio programming for a while now, and I'm excited by what I see in Chirp. I have already completely reverse-engineered a couple of Icom radios and I have been using very crude programs with hard-coded values (written in C nonetheless!) to program my radios thus far. However, I have written extensive documentation about these radios. I'm not sure how Chirp's structure is set up, but I assume there is some sort of modular API to add new radio implementations quickly.

Also, it looks like the project uses Subversion. Would I be correct in that assumption?

Thanks, and I look forward to possibly contributing to an OSS project.
