From Ghostscripts Projects.htm I find ...
Ghostscript as an Active-X COM Object.
In order to integrate Ghostscript into XMetaL and
other applications it would be convenient for
Ghostscript to be distributed as a COM object along
with the current gswin32.exe, gswin32c.exe and
Can you tell me how do you see the interpreter
working in a content authoring tool like XMetaL?
