| 35 # action_makenames.py is a harness script to connect actions sections of |
| 36 # gyp-based builds to make_names.pl. |
| 37 # |
| 38 # usage: action_makenames.py OUTPUTS -- INPUTS [-- OPTIONS] |
| 39 # |
| 40 # Multiple OUTPUTS, INPUTS, and OPTIONS may be listed. The sections are |
| 41 # separated by -- arguments. |
| 42 # |
| 43 # The directory name of the first output is chosen as the directory in which |
| 44 # make_names will run. If the directory name for any subsequent output is |
| 45 # different, those files will be moved to the desired directory. |
| 46 # |
| 47 # Multiple INPUTS may be listed. An input with a basename matching |
| 48 # "make_names.pl" is taken as the path to that script. Inputs with names |
| 49 # ending in TagNames.in or tags.in are taken as tag inputs. Inputs with names |
| 50 # ending in AttributeNames.in or attrs.in are taken as attribute inputs. There |
| 51 # may be at most one tag input and one attribute input. A make_names.pl input |
| 52 # is required and at least one tag or attribute input must be present. |
| 53 # |
| 54 # OPTIONS is a list of additional options to pass to make_names.pl. This |
| 55 # section need not be present. |
