 # Top level makefile for building ipfw kernel and userspace.
 # You can run it manually or also under the Planetlab build.
 # Planetlab wants also the 'install' target.
+#
+# To build on system with non standard Kernel sources or userland files,
+# you should run this with
+#
+#	make KERNELPATH=/path/to/linux-2.x.y.z USRDIR=/path/to/usr
+#
+# We assume that $(USRDIR) contains include/ and lib/ used to build userland.
