+The YAZ proxy uses a configuration file in XML and libxml2 is required
+in order for the config facility to work. Many systems already have
+libxml2 installed. In that, case remember to get the devel version
+of that as well (not just the runtime). Libxml2 can also be compiled
+easily on most systems. See http://www.xmlsoft.org/ for more
+information.
