-adhere to these standards.  Therefore, if this variable is set and you
-violate one of the @sc{posix} standards in the way you phrase a
-command, for example, @GNUTAR{} will not allow the
-command and will signal an error message.  You would then have to
-reorder the options or rephrase the command to comply with the
-@sc{posix} standards.
