This operation is useful when you have to work on more than one release of the same project. When you check out a project, you specify a release and version. The project is then opened in Eclipse. To check out more than one version of a project, all you need to do is to perform a normal project check out operation. The project will be created in Eclipse with its name constructed using underscore (_) and project’s version.
For example, assume that Synergy has a non-modifiable project Px and its version is 1. When you perform a checkout operation, Px is checked out to version 2. In Eclipse, its name will appear as Px. To work on another release, you want to checkout this project again. This time, its version is 3. In Eclipse, this project will be created as Px_3.
