Sweet Build is a build tool. It tracks dependencies and timestamps between files to determine which are out of date and then carries out actions to bring those files up to date.

It’s main difference to these tools is that it allows scripts to make arbitrary passes over the dependency graph to correctly establish dependency relationships.
