    ===========

  The purpose of this tool is to allow you to determine the
  differences in your environment between two points in time,
  and to undo and reapply those differences at a later time.

  Usage is as follows:

 $ env-watcher usage
    Print this usage information.

 $ env-watcher start MyName
    Start a recording session called "MyName".

 $ env-watcher stop MyName
    Stop the recording session called "MyName".
    The difference between the start and the stop point will
    be saved to a state called "MyName" and are now available
    for undoing and redoing.

 $ env-watcher undo MyName
    Revert all changes made to the environment in the recording
    session called "MyName".
    Can be called on an open session to revert to the inital state.

 $ env-watcher redo MyName
    Reapply the changes made to the environment in the recording
    session called "MyName"
