+# Makefile for the different targets used to generate full packages of a kernel
+# It uses the generic clean infrastructure of kbuild
+
+# RPM target
+# ---------------------------------------------------------------------------
+# The rpm target generates two rpm files:
+# /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.
+
+# Remove hyphens since they have special meaning in RPM filenames
