From Issue #47March 1998
The section "Ghostscript as a Document Post-Processor and Previewer" of this article sounds very interesting but doesn't work. More explanation would be nice.
Try to isolate the problem. Do the individual utilities run correctly from the shell prompt? Then, do the shell scripts run correctly from the shell? If they don't, then try to include the error messages. If they do, then try to include the debug output from the Emacs interpreter. Also include the version of each utility, so I can duplicate the errors produced by newer versions. Or, you can follow these procedures, and submit a patch.
