Two test-programs of interest are generated when you type 'make' at
-the top level. server/ztest and yazlib/cli. Ztest is a dummy database
+the top level. server/ztest and client/client. Ztest is a dummy database
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.

+client osi:[<tsel>'/']<hostname>:<port>
to connect to an OSI SR target (this requires mOSI-support). To connect to
the DANBIB test target, you might use:
-cli osi:0103/find2.denet.dk:4500
+client osi:0103/find2.denet.dk:4500

+The current query language is a bit awkward, but functional:
+
+query ::= complex | simple | attr query.
+complex ::= operator query query.
+operator ::= '@and' | '@or' | '@not'.
+simple ::= term | set.
+term ::= <word> | '"' <term> ... '"'.
+set ::= '@set' <setname>.
+attr ::= '@attr' <number> '=' <number>.

+Eg.:
-CLI supports CCL-queries, with the mapping between qualifiers and
-attribute values specified in the file default.bib in the working
-directory. Use '?' to get a list of the available commands.

-yazlib - This module implements the transport transparency
+comstack- This module implements the transport transparency
stack (COMSTACK). The comstack implements a generic interface
for exchanging BER-encoded records over a network. It supports
the 'American' mode of exchanging the records straight over
previous modules into libyaz.a.
lib - The libraries. Primarily libyaz.a.
