@chapter Finding the Apple driver
ift-extract extract Built-in iSight firmware from Apple iSight
driver. This driver is located at
/System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBVideoSupport.kext/Contents/MacOS/AppleUSBVideoSupport
on your Mac OS X root partition.
There is several version of this driver depending on driver version or
host architecture (PowerPC or x86). Thus, ift-extract must determine
know the variant of the driver in order to properly extract the
firmware.
Any AppleUSBVideoSupport file starting with those shipped with iMac G5
iSight must work. If not, @b{please report unknown
AppleUSBVideoSupport} at bugreport mail address with machine type and
OS X version.
@node Options
@chapter Command line options
