+.BR SBCL_HOME
+This variable controls where files like "sbclrc", "sbcl.core", and the
+add-on "contrib" systems are searched for. If it is not set, then
+sbcl sets it from a compile-time default location which is usually
+/usr/local/lib/sbcl/ but may have been changed e.g. by a third-party
+packager.
