We would be happy to include in the Ghostscript documentation the contact information for anyone who wants to offer such support. What about commercial use? GNU Ghostscript may not be incorporated into commercial products which forbid copying or for which customers cannot obtain source code for no more than the cost of reproduction, although it may be distributed "aggregated" with commercial products; AFPL Ghostscript may not be incorporated into commercial products at all, and may be distributed commercially only under extremely limited circumstances.
