 * The CVS state of a file.

 * <P>
 * Specifies the state of a CVS file on disk, as a result of the CVS command
 * 'cvs -nq update' to get status, or 'cvs -q update' to do the update.
 * The former describes the action the latter would take (-n tells cvs not to
 * change any disk files).
 * <P>
 * A file for which no state is given as a result of this command is up-to-date.
