# Translate SubX files to a bootable disk image.
#
# 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 top level is in general not as rigorous about avoiding dependency cycles
# as the lower-level tools in linux/
