+About the proxy
+---------------
 
 For the proxy the actual target is determined in by the OtherInfo
 part of the InitRequest. We've defined an OID for this which we call
-PROXY. OID is 1.2.840.10003.10.1000.81.1.

-      oid          [5]  IMPLICIT OBJECT IDENTIFIER}}
+      oid                      [5]  IMPLICIT OBJECT IDENTIFIER}}

   InfoCategory ::= SEQUENCE{
-      categoryTypeId  [1]   IMPLICIT OBJECT IDENTIFIER OPTIONAL,
-      categoryValue  [2]   IMPLICIT INTEGER}
+      categoryTypeId   [1]   IMPLICIT OBJECT IDENTIFIER OPTIONAL,
+      categoryValue    [2]   IMPLICIT INTEGER}
 
 The InfoCategory is present with categoryTypeId set to the PROXY OID
 and categoryValue set to 0. The information in OtherInformation uses
 characterInfo to represent the target using the form target[:port][/db].
 
-For the client that doesn't set the PROXY OtherInformation, a default
+For clients that don't set the PROXY OtherInformation, a default
 target can be specified using option -t for proxy.
 
 Example:
   We start the proxy so that it listens on port 9000. The default
-  target is Bell Labs Library unless it is specified by a client in
+  target is Bell Labs Library unless it is overridden by a client in
   the InitRequest.
 
      $ ./yaz-proxy -t z3950.bell-labs.com/books @:9000
 
   The client is started and talks to the proxy without specifying
   a target. Hence this client will talk to the Bell Labs server.
+
      $ ./yaz-client localhost:9000
 
   The client is started and it specifies the actual target itself.
+
      $ ./yaz-client -p localhost:9000 bagel.indexdata.dk/gils
 
   For ZAP the equivalent would be
      proxy=localhost:9000
      target=bagel.indexdata.dk/gils
   Simple, huh!

+ZOOM-C++
+--------
+
+The ZOOM library in this distribution implements the ZOOM C++ binding
+described on the ZOOM web-site at 
+	http://zoom.z3950.org/bind/cplusplus/index.html
+It provides a simple but powerful API for constructing Z39.50 client
+applications.  See the documentation in doc/zoom.xml for much more
+information.
