Overview
In ClearCase, a UCM baseline typically represents a stable configuration for a component. A baseline identifies activities and one version of every element visible in one or more components. The ClearCase Component Tree Browser is a GUI that displays the baseline history of a component. You can use it to compare the contents of two baselines.
This tool mentor is applicable when running Microsoft Windows.
