When a new vendor release comes out, we build it with our "official" compiler settings for the different platforms, branch the headers from the source and combine them into a convenient "SDK" tree, sometimes tweak something here or there, and update the document. Amounts to several GB being checked in from multiple machines. Occasionally a developer (usually me, but others too) needs to commit changes back to our central repo vendor tree. I suppose we could do that into a separate repository and then define parts of that as a git submodule. Hmm, reading http://book.git-scm.com/5_submodules.html http://book.git-scm.com/5_submodules.html I don't see how to do that with git without using 100 GB on the library dev machines.
