justbuild is a generic build system supporting multi-repository builds. A peculiarity of the tool is the separation between global names and physical location on the one hand, and logical paths used for actions and installation on the other hand (sometimes referred to as "staging"). The language-specific information to translate high-level concepts (libraries, binaries) into individual compile actions is taken from user-defined rules described by functional expressions.
Designated targets are taken entirely from cache, if the repositories transitively involved have not changed. So, by making good use of the multi-repository structure, the action graph can be kept small. Remote build execution is supported and the remote-building of cachable targets can be fully delegated to a service (provided by the tool itself); when doing so, it is not necessary to have the dependencies locally (neither as source nor as binary).
