 # Generates the hashed_ad_networks.[h,cc] files. Takes an input the name of a
 # file with all ad network host patterns, new-line separated. If given an
 # optional root output file name, generates the files <root_output_name>.h and
 # <root_output_name>.cc. If no output name is given, the output name is
 # 'hashed_ad_networks'.
