-# Exactly two outputs must be specified: a path to each of CSSPropertyNames.cpp
-# and CSSPropertyNames.h.
-#
-# Multiple inputs may be specified. One input must have a basename of
-# makeprop.pl; this is taken as the path to makeprop.pl. All other inputs are
-# paths to .in files that are used as input to makeprop.pl; at least one,
-# CSSPropertyNames.in, is required.
