 * FILE:        cli.h
 *
 * DESCRIPTION: This file declares the class Cli which is a user of the 
 *              symbol database and, as such, derives from DbUser.
 *              The cli (Command Lime Interface) provides a single shot
 *              database querying to the freescope user. As soon as the 
 *              result has been displayed, the program should exit.
