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. | |
