Nuclos Open Source ERP system

Nuclos is a click-to-build system for non-technical users to build full-customized java enterprise applications. The server is a spring-based web application running on Apache Tomcat. There are two clients: A swing-based fat-client running with Java WebStart, and a webclient which can be used on any modern browser. Nuclos is released under the GNU Affero General Public License (Version 3.0), and hence is 100% open source. This is a git representation of the current nuclos development.
