/** 
 * This Sample application in BeanShell makes use of CLI API's to create a 
 * Dedicated CLISession and send Synchronous CLI Commands to the Device 
 * according to the options provided.
 *
 * Options:
 * [-s]                        - Dedicated(d) or Nondedicated(nd) session. Default is Dedicated.
 * [-n]			       - Remote port. The default is the telnet port(23).
 * [-cp] 		       	 - Command Prompt. This is the prompt displayed by the device 
                                 for each command. Default is '$'
 * [-lp]		       	 - The login Prompt. This is the prompt that the device 
                                 issues for getting the username. Default is 'login:'
 * [-pp]		       	 - The Password Prompt. This is the prompt that is issued by 
                                 the device for getting the password. Default is 'Password:'
 * RemoteHost	  Mandatory  - The host to which the session is to be established.
 * [-l]                        - One of the user name/login name  present in the remotehost.
 * [-p]                        - Password for the user.
 * [-d]                        - Set Debugger ( true or false ). Default is false. 
 * Command 	  	  Mandatory  - This represents the actual command sent to the Host.
 *
 * Example Usage: CliSyncApp localhost -l guest -p guest "ls -l"
