Hi,
This adds the --with-kernel-includes configure option to
libnetfilter_queue and creates a README. This option allows compiling
with kernel headers not located at /usr/include.

+libnetfilter_queue - userspace library for handling queued network packets
+(C) 2005-2009 Netfilter Core Team <coreteam@xxxxxxxxxxxxx>
+===========================================================================
+
+What is netfilter_queue?
+
+netfilter_queue enables the kernel packet filter to queue network packets
+to userspace, using the nfnetlink transport layer. These packets can then be
+inspected and/or altered by a userspace program and reinjected in the kernel
+network stack.
+
+
+What is libnetfilter_queue?
+
+libnetfilter_queue is a userspace library providing an API to packets that
+have been queued by the kernel packet filter. It is part of a system that
+deprecates the old ip_queue / libipq mechanism. libnetfilter_queue has been
+previously known as libnfnetlink_queue.
+
+
+Prerequisites for libnetfilter_queue
+
+libnetfilter_queue requires libnfnetlink and a kernel that includes the
+nfnetlink_queue subsystem (i.e. 2.6.14 or later).
+You can specify the location of your kernel sources using the
+"--with-kernel-includes" configure option.
+
+
+Where can I find documentation?
+
+At the moment, you will have to RTFS. Sorry, but we have barely enough
+manpower to keep development ongoing. If you want to contribute documentation,
+please contact us.
+
+
+It has bugs. Where do I report them?
+
+Please report all libnetfilter_queue bugs to https://bugzilla.netfilter.org/,
+using the "libnetfilter_queue" Product.
+
+
+Where do I get support?
+
+The netfilter@xxxxxxxxxxxxxxx and netfilter-devel@xxxxxxxxxxxxxxx
+mailinglists serve as support forum.
