#!/bin/sh
# Translate given SubX files to 'baremetal', a raw disk image that can boot and
# run without any OS.
#
# A couple of gotchas:
# * Many phases here have no error-checking. Perhaps I should use a
#   version of translate_subx_debug for baremetal.
# * Don't pass in numbered .subx files without translated .mu files. Our test
#   harness is in test.mu, and only Mu programs can run tests in baremetal.
#
# The baremetal directory is in general not as rigorous about avoiding
# dependency cycles as the top-level.
