-# The script uses a subsequent grep pass to remove #include files

-# In order to handle include paths correctly, you need to provide
-# a compile DB (aka compile_commands.json).
-# You can create it in one of the following ways:
-# "gn gen --export-compile-commands path/to/out"
-# "tools/clang/scripts/generate_compdb.py -p path/to/out > compile_commands.json"
-# If "out/Default" exists, the script will attempt to generate it for you.

-# To get iwyu on Debian/glinux, do "sudo apt-get install iwyu".

-# Set this to 1 to get more debug information.
-# Set this to 2 to also get a dump of the iwyu tool output.
