The extract-firmware.sh script is the OLDER rendition that does not support as 
many platforms. The -NG scripts are REPLACEMENTS. The old ones are kept on the 
off chance they handle some format the new ones don't. Craig - honestly, do we 
need the old scripts still? It won't hurt my feeling is the answer is NO, but I 
assumed Yes.

The extract-ng script should properly extract anything with squashfs/cramfs 
file systems (it only extracts the first file system so it doesn't support any 
images with multiple file systems). 

Re-building is a little trickier of course, but build-ng should reassemble 
anything extracted by extract-ng and patch up any uImage/TRX headers properly 
(multiple and/or mixed headers are OK); it also assumes that the kernel 
precedes the filesystem in the firmware image so anything not conforming to 
that layout may not work.

So I *think* that the NG scripts will cover all of the firmware that is 
supported by the extract_firmware/build_firmware scripts? I don't know for sure 
though and didn't test. If you don't think that the old scripts provide any 
advantages you can of course take them out if you wish, but I'll leave that at 
your discretion since you know more about them (and the firmware they were 
tested against) than I do.
