Yaz4j is a Java binding for the high-level, client-side portion of the YAZ
toolkit known as the ZOOM API. With Yaz4j you can program clients for YAZ-

+You will need the JDK, Maven, Swig and YAZ development packages.

+If yaz-config is in your PATH, the following command should suffice:
+
+ mvn install
+
+If yaz-config is not in your PATH, you'll have to tell where YAZ is located:
