+Subject: FIX: fix build error with libxml2 2.12.0
+
+libxml2 2.12.0 changed which header file to define functions
+and header inclusion. Due to this refactoring, some yaz source
+files need additional inclusion of libxml2 header file,
+especially for libxml/parser.h .
+
+Closes #102 .

+SUMMARY="C/C++ toolkit for Z39.50v3 clients and servers"
+DESCRIPTION="YAZ is a C/C++ library for information retrieval applications using the Z39.50/SRU/\
+Solr protocols for information retrieval.
+
+Properties of YAZ:
+* Complete Z39.50 version 3 support. Amendments and Z39.50-2002 revision is supported.
+* Supports SRU GET/POST/SOAP version 1.1, 1.2 and 2.0 (over HTTP and HTTPS).
+* Includes BER encoders/decoders for the ISO ILL protocol.
+* Supports Apache Solr Web Service version 1.4.x (client side only)
+* Supports the following transports: BER over TCP/IP (RFC1729), BER over Unix local socket, and \
+HTTP 1.1.
+* Secure Socket Layer support using GnuTLS. If enabled, YAZ uses HTTPS transport (for SOAP) or \
+'Secure BER' (for Z39.50).
+* Offers ZOOM C API implementing Z39.50, SRU and Solr Web Service.
+* The YAZ library offers a set of useful utilities related to the protocols, such as MARC \
+(ISO2709) parser, CCL (ISO8777) parser, CQL parser, memory management routines, character set \
+conversion.
+* Portable code. YAZ compiles out-of-the box on most Unixes and on Windows using Microsoft Visual \
+C++.
+* Fast operation. The C based BER encoders/decoders as well as the server component of YAZ is \
+very fast.
+* Liberal license that allows for commercial use of YAZ."
