# To override the automatic Linux source tree determination, pass the
# pathname for the kernel that you want to compile on the command line,
# like this:
# make TREE=/usr/my-kernel-tree/include
#
#
# ***** NOTE NOTE NOTE NOTE NOTE *****
# Because some distributions patch 2.2.x kernels to make kill_fasync have
# three parameters, this script tries to determine, via the examination of
# header files, if your kernel has been patched. If this detection is
# incorrect, you can override the value on the command line, like this:
# make PARAMS=2
# or
# make PARAMS=3
