In the new application builder in 4D 2004, you can define each plug-in that you want to use in your single-user or client-server application. When you build your application, click on the Plug-ins tab to display the list of usable plug-ins. By default, all plug-ins that are listed are checked. To deselect a plug-in, click the check box next to it. Once you have all the plug-ins that you want to incorporate into your application, clicking the build button will build the application with the plug-ins.
