ploticus 2.30 data display engine. Software, documentation, and examples. Copyright 1998-2004 Stephen C. Grubb (scg@jax.org) The home page for PLOTICUS is http://ploticus.sourceforge.net The source code, binaries for some platforms, documentation, and examples may be freely downloaded from that site. About the author This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. A copy of the GNU General Public License should be present with the code, in file GPL.txt. A copy of the GNU General Public License may also be obtained from: Free Software Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA. Clarification (my view):
The GPL allows you to _use_ ploticus to produce graphs for any lawful commercial or
noncommercial purpose, including providing manual or automated services for a fee.
Selling or distributing ploticus code to other parties in a non-GPL offering is prohibited,
with the following exception. The "pl" executable may be included as a reporting utility
and bundled with a non-GPL product if all of these conditions are met:
1) ploticus must be invoked using a standard generic "pl" executable, not the libploticus API;
2) "pl" is used to produce specific predetermined reports and graphs;
3) ploticus graphics capability may not be offered as an additional cost option;
4) the product must be viable in its own right and essentially usable with or without ploticus;
5) ploticus identity and authorship must be clearly stated and be visible to users, including the
fact that ploticus source code is freely available from http://ploticus.sourceforge.net.
If all of these conditions are met, then ploticus is effectively partitioned from the larger package,
and I consider the GPL to be attached only to ploticus and not the larger package.
If you have questions or need clarification please contact me - scg@jax.org . I take an active interest in seeing that these rules are adhered to, and request notification of any suspected violations.
