# target config::. If empty, the configuration tool
# is not run.
# DROPSCONF_TITLE - the main title in the configuration tool.
# DROPSCONF_DEFCONFIG - default config file
# DROPSCONF_CONFIG_IN - configuration defintion file
# DROPSCONF_CONFIG - config file
# DROPSCONF_CONFIG_H - generated config header file
# DROPSCONF_MACRO - macro to indicate inclusion of config header file
# DROPSCONF_HELPFILE - options help file
