      5 # This file is meant to be included into an action to invoke grit in a
      6 # consistent manner. To use this the following variables need to be
      7 # defined:
      8 #   grit_grd_file: string: grd file path
      9 #   grit_out_dir: string: the output directory path
     10 
     11 # It would be really nice to do this with a rule instead of actions, but it
     12 # would need to determine inputs and outputs via grit_info on a per-file
     13 # basis. GYP rules don't currently support that. They could be extended to
     14 # do this, but then every generator would need to be updated to handle this.
