This package contains unmodified external distributions of pcre and
zlib in the dist directory.  They were downloaded from the following
locations:

ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.00.tar.bz2

http://www.zlib.net/zlib-1.2.3.tar.gz

Please refer to those packages for their licensing terms.

From here, you can build the qpdf-external-libs-bin.zip file as
available from the qpdf download site.  This package contains built
versions of those two libraries for both MINGW and MSVC.

To build the package, you be running in an MSYS environment (at least
1.0.11) with MINGW and MSVC both set up in your environment.  You must
also have ActiveState Perl and zip (from http://www.info-zip.org) in
your path.  Once set up, run ./build.sh to build the libraries and
create the zip file.  Run ./clean.sh to remove temporary files.

The resulting zip file can be extracted inside the qpdf source tree
for building under Windows.  For details, please see README.windows in
the qpdf source distribution.
