Clarification (my view):
<p>

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.
<br>
Note: This situation is addressed on the GPL page <a href="http://www.gnu.org/licenses/gpl-faq.html#GPLInProprietarySystem">here</a>.
<p>

If you have questions or need clarification please contact me - stevegrubb@gmail.com &nbsp;.
I take an active interest in seeing that these rules are 
adhered to, and request notification of any suspected violations.
