That might work. I guess the stdlib/interpreter split should also
think about how to split up the docs.

And yes, clone might be a better word to use in this context. The
repository word is slightly overloaded, in that it can be used both
for clone, or to distinguish the .hg part from the working dir part of
a clone, for example.

One problem with branches in DVCS is that there are so many kinds of
them. The SVN repository, for example, would now be reflected by all
of the clones of python-dev lineage (starting with the same changeset)
everywhere. Each of these clones represent a branch, in the sense that
someone can commit there and thus deviate from all other repositories.
If you commit twice from the same parent changeset in your clone, you
end up with two heads (on the same named branch), which are also
separate branches in the distributed global python-dev DAG. And all of
these are "unnamed" branches, possibly residing on the same named

The hg wiki is a good resource, but can be a bit disorganized. You
might also want to read the hgbook, which is slightly outdated but
should have thorough explanations. It's also available in dead-tree
