Prerequisite: The project that you want to version must first be in the workspace.
Tip: It is often preferable to synchronize resources with the CVS repository before versioning. This will ensure that there are no outstanding incoming or outgoing changes that might be accidentally excluded from the version.
To make a version of a project:
Tip: You can browse existing versions of your project by clicking on the Details button in the Tag Resources dialog. Clicking Refresh from Repository should populate the Existing Versions list. It is sometimes helpful to see existing versions before naming your new version.
