+# Script to compile 'mk' (and 'rc') without using 'mk' (nor 'rc') and generate
+# a bin/mk (and bin/rc) so that we don't need a BOOTSTRAP/Linux/386/bin/mk
+# like in kencc. Note that kencc has no BOOTSTRAP/Linux/386/bin/rc because
+# it assumes the presence of a shell and can work both with 'rc' and 'sh'.
 #
 # Note that right now to boostrap Xix we still need:
 #  - OCaml (which itself requires to bootstrap ocamllex, ocamlyacc and C)
 #  - a C compiler
 #  - /bin/sh
 #
+# Maybe at some point the assembler/linker/compiler in this repo will
+# be able to bootstrap itself and we will just need an ocamlrun bytecode
+# version of those tools in BOOTSTRAP/.

 # This file was mostly auto-generated by copy-pasting a trace of mk.
