VMware Studio 2.6 Release Notes – New features, known issues
VMware Studio includes a Web browser interface that controls an extensive build system, simplifying the development of virtual appliances and vApps (multi-VM appliances combined as a unit for easy management). VMware Studio provides an Eclipse plug-in so you can use the same integrated development environment for programming your applications as for packaging components and running the Web browser interface. VMware Studio also has a command-line interface to assist you with automated builds. Linux-based virtual appliances can be patched from an optional update repository. Windows-based virtual appliances can be configured with Sysprep and boot scripts.
