/**
 * A base class for creating tasks for executing commands on ClearCase.
 * <p>
 * The class extends the 'exec' task as it operates by executing the cleartool program
 * supplied with ClearCase. By default the task expects the cleartool executable to be
 * in the path, * you can override this be specifying the cleartooldir attribute.
 * </p>
 * <p>
 * This class provides set and get methods for the 'viewpath' and 'objselect'
 * attribute. It also contains constants for the flags that can be passed to
 * cleartool.
