-# This script enumerates the files in the given directory, writing an empty
-# stamp file and a .d file listing the inputs required to make the stamp. This
-# allows us to dynamically depend on the grit sources without enumerating the
-# grit directory for every invocation of grit (which is what adding the source
-# files to every .grd file's .d file would entail) or shelling out to grit
-# synchronously during GN execution to get the list (which would be slow).
-#
-# Usage:
-#    stamp_grit_sources.py <directory> <stamp-file> <.d-file>
