 /*
- * When using cf_get_opt(), you must prefix your own short/long options by the
- * CF_(SHORT|LONG)_OPTS.
+ * cf_getopt() takes care of parsing the command-line arguments, loading the
+ * default configuration file (cf_def_file) and processing configuration options.
+ * The calling convention is the same as with GNU getopt_long(), but you must prefix
+ * your own short/long options by the CF_(SHORT|LONG)_OPTS or pass CF_NO_LONG_OPTS
+ * of there are no long options.
  *
- * 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.
