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