     Contrary to config.status, it doesn't use CONFIG_FILES or CONFIG_HEADERS
     variables.
 
     Without the -n option, this program acts as config.status and considers
     the current directory as the top object directory, even when config.status
     is in a different directory. It will, however, treat the directory
     containing config.status as the top object directory with the -n option.
 
-    The --recheck option, like with the original config.status, runs configure
-    again, with the options given in the "ac_configure_args" subst.
-
     The options to this function are passed when creating the
     ConfigEnvironment. These lists, as well as the actual wrapper script
     around this function, are meant to be generated by configure.
     See build/autoconf/config.status.m4.
