[Scons-users] Scanners

[William Blevins]

I don't believe there is a magic switch for this. I assume the real issue
is that the order of the dependencies must always be the same, and not
necessarily sorted alphabetically. What tool are you using that requires
sorting? Is this related to caching?

V/R,
William
