 # Instantiate grit. This will produce a script target to run grit, and a
 # static library that compiles the .cc files.
 #
 # Parameters
 #
 #   source
 #       Path to .grd file.
 #
 #   grit_flags (optional)
 #       List of strings containing extra command-line flags to pass to Grit.
 #
 #   deps  (optional)
 #   visibility  (optional)
 #       Normal meaning.
 #
 # Example
 #
 #   grit("my_resources") {
 #     source = "myfile.grd"  # source is required.
 #     grit_flags = [ "-E", "foo=bar" ]  # Optional extra flags.
 #     # You can also put deps here if the grit source depends on generated
 #     # files.
