- <ulink url="http://www.indexdata.dk/yazplusplus/">YAZ proxy</ulink>
- 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="&url.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:
