Please explain further.  I thought that PDF was a sort of
PostScript-ng, with an unobfuscated (or even documented) file format.
I guess I formed that opinion based on the ability of Ghostscript to
print and view PDF files.  Is it based on reverse engineering PDF
files?  Do PDF files contain IP protection features?  Does Adobe think
its developers and/or users copyright infringers under the DMCA?
