From the project README

An excerpt from the repository, fetched Nov 13, 2026.

Read the project’s introduction
redo - a recursive build system Smaller, easier, more powerful, and more reliable than make. This is an implementation of Daniel J. Bernstein's redo build system. He never released his version, so other people have implemented different variants based on his published specification. This version, sometimes called apenwarr/redo, is probably the most advanced one, including parallel builds, improved logging, extensive automated tests, and helpful debugging features. To build and test redo, run: ./do -j10 test To install it, run something like this: DESTDIR= PREFIX=/usr/local ./do -j10 install View the documentation via readthedocs.org Visit the source code on github Discussions and support via the mailing list (archives).

It leaves that for other tools (and rightly so, I believe). Another important tool not listed: premake (v3 and v4, which are very different). If you're building a C++ centered project that needs to work on Windows, Xbox, Mac, Linux, PS3 and others - it will keep whatever is left of your sanity given the situation, and help you get the job don
