-# /usr/src/packages/SRPMS/kernel-2.6.7rc2-1.src.rpm
-# /usr/src/packages/RPMS/i386/kernel-2.6.7rc2-1.<arch>.rpm
-# The src.rpm files includes all source for the kernel being built
-# The <arch>.rpm includes kernel configuration, modules etc.
-#
-# Process to create the rpm files
-# a) clean the kernel
-# b) Generate .spec file
-# c) Build a tar ball, using symlink to make kernel version
-# first entry in the path
-# d) and pack the result to a tar.gz file
-# e) generate the rpm files, based on kernel.spec
-# - Use /. to avoid tar packing just the symlink
-
-# Note that the rpm-pkg target cannot be used with KBUILD_OUTPUT,
-# but the binrpm-pkg target can; for some reason O= gets ignored.
