I would eventually like to move this to become a part of the tutorial,
but anyway, this was an excellent post that describes how topic
branches can be used to keep track of local changes.
I think these are useful, and I think putting them in a new "howto"
directory might help some users until we get to the point of splitting
up the tutorial to be easier to read.
Given the authorship, I think it's safe to put these in the repository.
