The primary output of the source here is the lib/libyaz.a library,
which contains support functions for implementing the server or client
role of Z39.50/SR.

-how to compile the software using Microsoft Visual C++.

On Unix, GNU configure is used to configure YAZ and generate Makefiles.
Type "./configure", then "make" to build YAZ.
Two test-programs of interest are generated when you type 'make' at the
-top level: ztest/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.

Use '?' to get a list of the available commands.
The current query language for the find command is a bit awkward, but
functional:
-query ::= ['@attrset' <attribute-set>] rpn
-rpn ::= complex | simple | attr rpn
-complex ::= operator rpn rpn
-operator ::= '@and' | '@or' | '@not' | '@prox' proximity
-simple ::= term | set.
-term ::= <word> | '"' <term> ... '"'.
-set ::= '@set' <setname>.
-attr ::= '@attr' [<attribute-set>] <number> '=' <number>.
-proximity ::= exclusion distance ordered relation which unit
-exclusion ::= '1' | '0' | 'void'
-distance ::= <number>
-ordered ::= '1' | '0'
-relation ::= <number>
-which ::= 'known' | 'private'
-unit ::= <number>
+ query ::= ['@attrset' <attribute-set>] rpn

The sort command takes a sequence of sort specifications. A sort
specification holds a field (sort criteria) and is followed by flags.
