Good catch! Indeed libgs9 ships with a few files arguably usable only as examples: /usr/share/ghostscript/9.27/lib/PDFA_def.ps /usr/share/ghostscript/9.27/lib/PDFX_def.ps The files document both inline and in VectorDevices.htm that they should be edited before use. I am hesitant to moving or patching those files, though, because (as you demonstrate above) it _is_ possible with some path juggling to use those files as-is, and both upstream and consuming code might rely on the files. Even if never used for anything as examples, I see no harm in leaving the files where they are just to be on the safe side. More sensible to me would be to symlink the files to .../doc/libgs9/examples to advertise them as usable as such. How do you think about my alternative approach?
