 * gnuhelp.c - the texts `required' in interactive programs by the GPL.
 *		(In case it's not clear, I don't like this `requirement'.
 *		This file implements it in a painfully obnoxious way to
 *		take the piss.)

/* #ifdef DIATRIBE
 *
 * I put `requirement' in quotes as it's not really a requirement.
 * While the "How to Apply These Terms to Your New Programs" appendix
 * instructs you to do it in typical RMS my-way-is-best fashion ;-),
 * the last sentence of paragraph 2c clearly shows that it is NOT
 * an cast-iron requirement.
 *
 * "c) If the modified program normally reads commands interactively
 *  when run, you must cause it, when started running for such
 *  interactive use in the most ordinary way, to print or display an
 *  announcement including an appropriate copyright notice and a
 *  notice that there is no warranty (or else, saying that you provide
 *  a warranty) and that users may redistribute the program under
 *  these conditions, and telling the user how to view a copy of this
 *  License.  (Exception: if the Program itself is interactive but
 *  does not normally print such an announcement, your work based on
 *  the Program is not required to print an announcement.)"
 *
 * So if you *write* a program you don't have to do it, but once a
 * program *has* such an announcement the copyright owner is the
 * only person who can remove it (it can't be removed in derivative
 * works).
 *
 * Are we being sufficiently stupid yet?
