formatting: Remove segment parts, you can use template tags instead. Segment parts were used to switch formatters insides a given content segment, but that's also achievable with template tags like `pcformat` in Jinja to some degree. It's not totally the same but removing it simplifies the code and improves performance.

@task
def genmessages():
    root_dir = 'garcon/messages'
    out_dir = 'piecrust/resources/messages'
    run('python chef.py --root %s bake -o %s' % (root_dir, out_dir))
    os.unlink('piecrust/resources/messages/index.html')
