#
# 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.
