/*
* autoscript allows a remote host to download a command file and ,
* optionally , binary data for automatically updating the target . For
* example , you create a new kernel image and want the user to be
* able to simply download the image and the machine does the rest .
* The kernel image is postprocessed with mkimage , which creates an
* image with a script file prepended . If enabled , autoscript will
* verify the script and contents of the download and execute the
* script portion . This would be responsible for erasing flash ,
* copying the new image , and rebooting the machine .
* The " source " command allows to define " script images " , i . e . files
* that contain command sequences that can be executed by the command
* interpreter . It returns the exit status of the last command
* executed from the script . This is very similar to running a shell
* script in a UNIX shell , hence the name for the command .
