A Short docstring here explaining what the generator does wouldn't be amiss.
You could probably just copy your commit message.

please sort these as:
__future__
python builtins

3rd party modules

local modules

(in this case mako is the only 3rd party module, everything else is correct.)

Most of piglit puts the """ and the first lone of the docstring on the same line

This line is really long
