The VCF Builder is intended to be a useful development platform that can be extended for editing, building, compiling, and potentially debugging development projects. It's somewhat similar to Eclipse but far less general. Where Eclipse claims to be a general to tool to build anything, the VCF Builder is targetted specifically at developers and development tools.

The VCF Builder is extended through the use of plug-ins. These can include new document types, custom document editors, custom configuration types, and debuggers. There are also plug-ins that can be written for version control as well. The VCF Builder shell itself provides a basic application shell that does the basics of maintaining windows, maintaining a workspace, project, and project items. It provides a basic view of project items, allowing for a customized graph of the internals of any given project item through it's plug-in interface. Support for basic text based search and replace is also provided.  For more information see the VCF Builder's documentation.
