5  * Permission to copy and distribute XV in its entirety, for non-commercial
6  * purposes, is hereby granted without fee, provided that this license
7  * information and copyright notice appear unmodified in all copies.
8  *
9  * Note that distributing XV 'bundled' in with any product is considered
10  * to be a 'commercial purpose'.
11  *
12  * Also note that any copies of XV that are distributed must be built
13  * and/or configured to be in their 'unregistered copy' mode, so that it
14  * is made obvious to the user that XV is shareware, and that they should
15  * consider donating, or at least reading this License Info.
16  *
17  * The software may be modified for your own purposes, but modified
18  * versions may not be distributed without prior consent of the author.
19  *
20  * This software is provided 'as-is', without any express or implied
21  * warranty.  In no event will the author be held liable for any damages
22  * arising from the use of this software.
23  *
24  * If you would like to do something with XV that this copyright
25  * prohibits (such as distributing it with a commercial product,
26  * using portions of the source in some other program, etc.), please
27  * contact the author (preferably via email).  Arrangements can
28  * probably be worked out.
29  *
30  * XV is shareware for PERSONAL USE only.  You may use XV for your own
31  * amusement, and if you find it nifty, useful, generally cool, or of
32  * some value to you, your non-deductable donation would be greatly
33  * appreciated.  $25 is the suggested donation, though, of course,
34  * larger donations are quite welcome.  Folks who donate $25 or more
35  * can receive a Real Nice bound copy of the XV manual for no extra
36  * charge.
37  *
38  * Commercial, government, and institutional users must register their
39  * copies of XV, for the price of $25 per workstation/X terminal or per
40  * XV user, whichever is less.  Note that it does NOT say 'simultaneous user',
41  * but rather, the total number of people who use XV on any sort of
42  * recurring basis. Site licenses are available (and recommended) for those
43  * who wish to run XV on a large (>10) number of machines.
44  * Contact the author for more details.
