+ The library (and therefore all the utilities) can access PCI registers
+either via the /proc/bus/pci interface present since Linux 2.1.82 or
+via direct hardware access (to be used with older kernels and also for
+hardware diagnostics). It's also capable of reading and interpreting
+register dumps printed by `lspci -x'. Unfortunately, there is no documentation
+on how to use the library yet, so if you want to play with it, just ask
+me for whatever you want.
