#
# This makefile attempts to compile the vhci core module and the
# libusb-vhci library by downloading known tarballs, hacking them
# a little and compiling them
# 
# This has been tested on debian, but coild possibly work in other
# distro. the only "real" dependency is to have the linux kernel
# header symlinked at /lib/modules/<your host kernel version/build
