[Scons-users] Does SCons has an automatic rebuild option ?

[Bruce Adams]

It sounds like what you want is a continous integration system. 

This is a slightly different job from a build tool and it usually makes more sense have the continousl integration system use
the build tool rather than to combine the two into.

I would recommend looking at Jenkins for a good open source continuous integration server though it might be overkill for your needs.
I don't know how well it plays with scons as it comes from java land but I have used it with some success on plain old makefile projects.
