To update a tool or feature, copy any new files into the base directory or appropriate subdirectories, overwriting the existing files.

The easiest way to support multiple versions is to treat each version as a distinct tool or feature. Essentially, you need to place each version in a unique base directory. It is also advisable to provide a unique Name entry in each control file so that each version can be distinguished by the user in the IDE.
