    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.

    The author wishes to be informed of and to maintain links to other development
    efforts involving ploticus.  Feel free to copy and use this nifty new logo
    in works that use ploticus, as a link back to this site.

    Can ploticus be used as part of a commercial package or service?  The GPL
    does not allow ploticus code to be used within proprietary software that is to
    be distributed to others.  However, for cases where ploticus is included as a
    separate, distinct reporting utility within a larger package, I interpret GPL
    section 2 as requiring that GPL be attached only to ploticus, and not to the
    entire product.  For this to be allowed: 1) the rest of your product must be
    considered an independent and seperate work in its own right; 2) ploticus must
    be invoked as a distinct, separate executable; 3) ploticus graphics capability
    may not be involved as an option at additional cost; 4) ploticus source code
    may not be modified or enhanced, except for changes to the Makefile or similar
    as needed for configuration or packaging; 5) ploticus identity and authorship
    must not be obfuscated of omitted-- a prominent statement must be visible to
    users to the effect that "graphs are produced using the Ploticus data display
    program (c) Steve Grubb.  The Ploticus program is freely downloadable at
    http://ploticus.sourceforge.net".  I also request that you notify me out of
    courtesy at scg@jax.org, and include a URL for your product.  If you have
    questions or need clarification in this area just ask.
