I'm currently doing a major overhaul of the source tree.
The major thing I'm doing is removing all the source codes for the packages and making it so the tree will DL the source when it is built. This will reduce the tree from a size of 3.5GB to under 300K or so. This will allow the source tree to be put into CVS so anyone can help out.
I'm also modifying how the packages are installed so the tree is much "cleaner", logical, and easier to understand.
