+.IX Subsection "1 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 \s-1OS\s0 X root partition.
+.PP
+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.
+.PP
+Any AppleUSBVideoSupport file starting with those shipped with iMac
+G5 iSight must work. If not, please report unknown AppleUSBVideoSupport
+at bugreport mail address with machine type and \s-1OS\s0 X version.
