To have a scalable system to build large software in Common Lisp, featuring deterministic separate compilation and enforced locally-declared dependencies.

You can find the latest released tarball of XCVB and all its dependencies ready-to-build in our release directory: http://common-lisp.net/project/xcvb/releases/
Status: Not yet a complete solution to fully replace ASDF, but it's already working and useful if you're ready to confront its current limitations. Examples included. It was last actively developed since mid-2012, and ASDF has made strides since. ASDF still has no story for cross-compilation, determinism, dependency-enforcement and scalability, but could be tweaked in that direction. XCVB has a very bad story for extensibility, but a richer dependency model,
