EDIT:
hmmm... needs reworking to move the FASTUSRLIBRESULTS kindle-lib results section into the EXACTRESULTS section I think. This is just ripped straight off an old device.
I'll check at some point. one day. Or someone else can.


could do with testing probably, but it's one of the iterations I used at some point.

Cheers.

EDIT:
REQUIRES! READELF!!! (forgot this was not included natively)
