-"""A wrapper to run yasm.
-
-Its main job is to provide a Python wrapper for GN integration, and to write
-the makefile-style output yasm generates in stdout to a .d file for dependency
-management of .inc files.
-
-Run with:
-  python run_yasm.py <yasm_binary_path> <all other yasm args>
-
-Note that <all other yasm args> must include an explicit output file (-o). This
-script will append a ".d" to this and write the dependencies there. This script
-will add "-M" to cause yasm to write the deps to stdout, so you don't need to
-specify that.

-# generating any compiled output so we need to do this in a separate pass.
-# However, outputting deps seems faster than actually assembling, and yasm is
-# so fast anyway this is not a big deal.
-#
-# This guarantees proper dependency management for assembly files. Otherwise,
-# we would have to require people to manually specify the .inc files they
-# depend on in the build file, which will surely be wrong or out-of-date in
-# some cases.
