``version`` is the Mercurial version string. If not defined,

``post_build_fn`` is a callable that will be called after building
Mercurial but before invoking WiX. It can be used to e.g. facilitate
signing. It is passed the paths to the Mercurial source, build, and
dist directories and the resolved Mercurial version.
``extra_packages_script`` is a command to be run to inject extra packages
into the py2exe binary. It should stage packages into the virtualenv and
print a null byte followed by a newline-separated list of packages that
should be included in the exe.
``extra_wxs`` is a dict of {wxs_name: working_dir_for_wxs_build}.

the build. These must match Feature names in one of the wxs scripts.
