Buck (and Bazel) both have rules to run and cache arbitrary rules/scripts as part of the build, assuming they produce one output: https://buckbuild.com/rule/genrule.html https://buckbuild.com/rule/genrule.html Some other benefits that may or may not be important: - Use the same build system for iOS/Android/Cxx/Python/D, etc. - Integrates with editing in IDEs. - Encourages modularization...more modules = more cache hits = faster builds
