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