-Two test-programs of interest are generated when you type 'make' at

-server which returns canned responses to all queries. It's good for
-verifying that the protocol works ok, and ztest.c shows a minimalistic
-implementation of the 'backend' interface.
+Windows programmers: refer to the file windows.txt which describes how
+to build the software using Microsoft Visual C++.

 
 

-Client is a linemode Z39.50 client. It supports a fair amount of the
-functionality of Z39.50v2/SR, but some things you need to enable or disable
-by recompilation. Its primary purpose is to excersise the package, and
-verify that the protocol works OK. It can be started by typing

+
+The sort command takes a sequence of sort specifications. A sort
+specification holds a field (sort criteria) and is followed by flags.
+If the sort critieria includes = it is assumed that the sort SortKey
+is of type sortAttributes using Bib-1. The integer before the = is
+the attribute type and the integer following the = is the attribute
+value. If no = is in the SortKey it is treated as a sortfield-type
+of type InternationalString. Flags observed are s (sort case
+sensitive), i (sort case insensitive), < (ascending), > (descending).
+Eg.:
+   1=4   i<                  (use is title, insensitive, ascending).
+   Title s>                  (String Title, sensitive, descending).
