/* extcmddcl.h: *//* This file must exist even if it is empty because it is #included in the *//* common file cmdtbl.c.  The purpose is to keep the common comand table   *//* file (common/cmdtbl.c) from being corrupted with non-generic commands   *//* that may be target specific. *//* It is the declaration portion of the code that must be at the top of    *//* the cmdtbl[] array. *//* For example:extern  int dummycmd();         Function declaration.extern  char *dummyHelp[];      Command help array declaration.*/
