Tup is pretty darn amazing. I've never had such a high success rate while writing build rules under it. "Once it builds, it has no bug". Not to mention the great speed to begin with.

Is there any similar build system? I know of https://github.com/droundy/fac, but it's not cross-platform

tup sounds similar to qbs. I found qbs to be a most amazing C++ build system, it's the only one I used that is

1) reasonably easy to use 2) very fast 3) very correct

Most build systems fail 3), usually 2) and often also 1).

What makes tup amazing is it traces which files a program touches, so assuming your programs obey the rule "I need to rerun if I have different command line arguments or something I read has changed", you get perfect dependencies for any program. I use it for running experiments with custom programs and scripts all the time, and it just refund the parts I need.
