Hi,

That sure looks like a continuous integration system to some extent.

I knew Jenkins but that is indeed too heavy for the task: the goal was
mainly to provide an easy and integrated way to easy the work for a
developer that spends a lot of time typing "scons" in his terminal.

Actually, before asking this question, I was already able to get a
satisfying and quick result with "watchmedo", the script that comes with
the [watchdog](http://pypi.python.org/pypi/watchdog) Python module.

The final command looked like:


> watchmedo shell-command --patterns="*.scss" --command="scons"


I was mainly thinking about having an option for that in SCons because
SCons has all the necessary information to do that more efficiently
(from a list of targets, it knows exactly what to watch and what to
rebuild).

That said, I can understand the rationale that SCons should just handle
"regular" one-time builds and not become an over-featured tool.

So anyway, thanks for your answers and feedback.

Regards,

Julien Kauffmann.
