Does the licensing of PDFlib allow for commercial use of
the
final application?
I'm afraid not [1]. I'm not sure this has changed since
PDFLib 5, which
is what I used in lpdf. I usually make a point to bind
to free software only.
Another (recent) entry in the OS PDF library world is:
<http://libharu.sourceforge.net/>
Nice, thanks for pointing this out. It looks similar to
PDFLib and so it
should be easy to write a Lua binding for it.
