# This script does two checks on the state of the copied chromium directories:
# 1. Ensure all files present are in their appropriate
# 2. Ensure all .h files with a corresponding .cc file in chromium have their
# .cc copied here.
# This should be run with your working directory at the root of the chromium
# clone.
# Usage: <ninja build dir> <chromium src directory>
# [run existence check]
# Both of the loops below will insert any files they want to add to a
# at the end of the first 'sources =' block in the file. It will insert it with
# only two spaces instead of four, so you can find files inserted by the script
# and adjust them as necessary.

# The following check can be skipped by not passing a path to gn to the script,
# since this operation is slow and can be considered more of a "clean up" than
# really iterative.
