The Bundles tool lists all bundles in the Weave installation, where bundles are small packets of code that together make up the Weave application. This tool gives the version of the bundle and the status of the bundle. It is useful for managing bundles if you're running customised bundles or have been provided a replacement bundle.
The Installed, Resolved, Starting and Active buttons on the bottom of the window can be used to restrict the display to bundles of a specific Status. You can also narrow down the list of bundles displayed by using the Filter box.
The Play and Stop buttons are used to start or stop the selected bundle.
