SUPPORT

I've tested this stuff under SysV and BSD, on Sun 3's 4's and 386's and
Sequents and Vaxen and HPs, with cc and gcc.  Nevertheless, I'm sure bugs
remain, and portability to systems like Amigas and IBM compatibles is
an interesting question.  Feedback is welcome; send bug reports,
enhancements, etc. to this address:

    jef@well.sf.ca.us
    apple!well!jef

When sending bug reports, always include the output from running any
PBMPLUS program with the -version flag.  Also include the type of
system you are on, what compiler you used, and whether you are using
Makefiles or Imakefiles.  I try to respond to bug reports and enhancements
promptly; say, within a week.

Also, if there is a new format or feature you would like to have added
to the package, feel free to drop me a line.  If it's a format, include
whatever documentation you have, and if possible a uuencoded sample.
My response time will depend on how busy I am, and how easy the job
looks.  If you need it right away, or it's a complicated job, you might
consider paying me; lately, that's how a lot of work on the package has
gotten done.

Finally, if you have access to Usenet, there's a newsgroup called
alt.graphics.pixutils which is specifically for discussion of image
conversion and editing packages such as PBMPLUS.  Posting stuff there
is even better than mailing it to me, since it lets other people help
out with the answers.


COPYRIGHTS

All the software in this package, whether by me or by a contributer,
has a copyright similar to this one:

    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.  This software is provided "as is" without express or
    implied warranty.

Many people get confused by this legalese, especially the part about
"without fee".  Does this mean you can't charge for any product that
uses PBMPLUS?  No.  All it means is that you don't have to pay me.
You can do what you want with this software.  Build it into your
package, steal code from it, whatever.  Just be sure to let people
know where it came from.
