# Set this to a lisp binary to use a custom bootstrap lisp compiler for
# SBCL. Leave as null to use the default. This is useful for local development
# of SBCL, because you can use your existing stock SBCL as a boostrap. On Hydra
# of course we can’t do that because SBCL hasn’t been built yet, so we use
# CLISP, but that’s much slower.
