SL-C3000 Updater Script
From OESF
Here's a highly commented walkthrough of the Sharp installer script.
With modifications to make it work properly.

## Define a temporary path
TMPPATH=/tmp/update
## These two file names are used by the script as storage locations
## when the original distribution files are chopped up.
## TMPDATA will end up with the actual data to be used whilst
## TMPHEAD contains a 16 byte version header stripped from the file.
TMPDATA=$TMPPATH/tmpdata.bin
TMPHEAD=$TMPPATH/tmphead.bin
## Config flags, set to 1 will inhibit processing of that file type
