I was actually referring to the build system of the single packages
here. If you want to hack on sugar you will likely have to hack (or at
least understand) some of the dependencies. I'm actually thinking to
sugar as gtk + dbus + matchbox + .... + our python bits, not as the
python code only. In this context using the same build system have some
If you want to write a sugar activity then this probably doesn't matter.
Btw it turns out jhbuild already supports distutils.

There will be activities wrote in C, or activities based on application
already using auto*. Getting these to use distutils would not be
productive (if possible at all).
But we are going to have documentation on how to write activities and
bless a build system for activities that are written from scratch in
python (which should be the most common case). setuptools might be a
good candidate for this. It would be positive to think and experiment in
this direction. We want to be really easy to write activities. And I
would never put auto* and really easy in the same phrase :)
