# Building RETRO To rebuild the core binaries, a simple `make` should suffice. This will leave you with `bin/rre` and `bin/repl`, as well as the `bin/listener` (wrapper for rre). If you make changes to the image sources (in `literate`) or to `interfaces/rre.forth`, you'll need to do a full build (toolchain + image + interfaces). This can be done by issuing a `make all` command.
