Licensing terms of embedded software
====================================
Some additional software with additional licensing terms is embedded
within the qpdf source distribution in "external-libs". This software
is not actually used by the qpdf build unless the
--enable-build-external-libs option is passed to ./configure. These
packages have their own licensing terms, both of which are compatible
with qpdf's license.
Zlib's license can be read in external-libs/zlib/zlib.h
PCRE's licensing terms can be found in external-libs/pcre/LICENSE.
PCRE's licensing terms require that we include the following
information:
Regular expression support is provided by the PCRE library package,
which is open source software, written by Philip Hazel, and
copyright by the University of Cambridge, England.
The sources to PCRE can be independently obtained from
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/
QPDF makes use of zlib and pcre for its functionality. These packages
can be downloaded separately from their own download locations, or
they can be downloaded in the external-libs area of the qpdf download
site.
The Rijndael encryption implementation used as the basis for AES
encryption and decryption support comes from Philip J. Erdelsky's
