I'm increasingly coming to think that we can avoid grunt.
- serve is handled by django runserver
- test running is handled by tox
- livereload could be handled by https://pypi.python.org/pypi/livereload
(it'd be really nice if someone could get support for this rolled in to
- watch is not handled by anything and it would be a shame to miss out on
automatic linting/testing, but I think we can live without it
So, the tools we need packaged for Linux are:
- jasmine (already in Fedora, I believe)
- selenium (I believe this is already done in Fedora and Debian)
- phantomjs (definitely already done!)

Could you perhaps elaborate on this? How do you see the workflow working
Given that Horizon already integrates with xstatic, it would be messy (and
potentially confusing) to include something so it *also* integrated with
bower. I was envisaging us creating a tool which generates xstatic packages
from bower packages. I'm not the first to think along these lines
I will be looking into creating such a tool today.

Yep, that is indeed their problem that they'd have already solved for the
existing xstatic packages.

If we stick with xstatic, we don't need this :)
