another program. This program must execute stand alone, e.g. an eCos
application or a Linux kernel.
</P
><P
>If the -w option is used, RedBoot will print a message and then
wait for a period of time before starting the execution. This is
most useful in a script, giving the user a chance to abort executing
a program and move on in the script.
