+# 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.
