/**
 * The change-admin-password command.
 * The remote command implementation presents a different
 * interface (set of options) than the local command.
 * This special local implementation adapts the local
 * interface to the requirements of the remote command.
 * 
 * The remote command is different in that it accepts the user name as 
 * an operand.  This command accepts it via the --user parameter. If the --user
 * option isn't specified, this command prompts for the user name.
 * 
 * Another difference is that the local command will prompt for the old 
 * password only once.  The default behavior for @Param for passwords is to 
 * prompt for the password twice.  *
