# Translate SubX files to a bootable disk image.

# This script uses emulation, so it does not require x86 or Linux. However it
|
|
# is slow.
|
|
#
|
|
# 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/
