-   is a Z39.50/SRW/SRU proxy. The proxy accepts connections from
-   protocol for information retrieval (client and server side).
-   While YAZ itself can be used from both C and C++ it is limited by the
-   common denominator C.
+   The <ulink url="http://www.indexdata.dk/yazproxy/">YAZ Proxy</ulink> is
+   highly configurable and can be used in a number of different
+   applications, ranging from debugging Z39.50-based applications
+   and protecting overworked servers, to improving the performance of
+   stateless WWW/Z39.50 gateways. Among other features, it includes:
