standardizing copyright/license notice delimiters in MIT source files.

[Will Fiveash]

I'm working on updating the third party copyright/license notifications
that are part of the Solaris krb packages and I see a number of
copyright/license notices in MIT code that are like:

/*
 * lib/krb5/krb/gen_seqnum.c
 *
 * Copyright 1991 by the Massachusetts Institute of Technology.
 * All Rights Reserved.
 *
 * Export of this software from the United States of America may
 *   require a specific license from the United States Government.
 *   It is the responsibility of any person or organization contemplating
 *   export to obtain such a license before exporting.
 *
 * WITHIN THAT CONSTRAINT, permission to use, copy, modify, and
 * distribute this software and its documentation for any purpose and
 * without fee is hereby granted, provided that the above copyright
 * notice appear in all copies and that both that copyright notice and
 * this permission notice appear in supporting documentation, and that
 * the name of M.I.T. not be used in advertising or publicity pertaining
 * to distribution of the software without specific, written prior
 * permission.  Furthermore if you modify this software you must label
 * your software as modified software and not distribute it in such a
 * fashion that it might be confused with the original M.I.T. software.
 * M.I.T. makes no representations about the suitability of
 * this software for any purpose.  It is provided "as is" without express
 * or implied warranty.
 *
 *
 * Routine to automatically generate a starting sequence number.
 * We do this by getting a random key and encrypting something with it,
 * then taking the output and slicing it up.
 */

The issue I have is that it is difficult to programmatically extract
just the copyright and license text since there is non-copyright/license
text in the same copyright block.  This task could be done more reliably
if there were some form of unique start and stop delimiters around the
copyright/license text that could be fed to sed for exaction purposes.
Thoughts?
