"""
Takes a single branch name and (if necessary) creates a new branch. Then,
populates the ``build/<branch>`` directory for the new branch using either
the parent branch or ``master``. Safe to run multiple times (after a rebase)
to update the build cache from master.
Also calls :method:`~giza.operations.build_env.fix_build_environment()` to
tweak the new build output to update hashes and on-disk copies of the
environment to prevent unnecessary full-rebuilds from sphinx.
