- * cf_def_file contains the name of a configuration file that will be
- * automatically loaded before the first --set option is executed. If no --set
- * option occurs, it will be loaded after getopt() returns -1 (i.e. at the end
- * of the configuration options). cf_def_file will be ignored if another
- * configuration file has already been loaded using the --config option. The
- * initial value of cf_def_file is DEFAULT_CONFIG from config.h, but you can
- * override it manually before calling cf_get_opt().
+ * The default configuration file can be overriden by the --config options,
+ * which must come first. During parsing of all other options, the configuration
+ * is already available.
