+# Script to build new Debian kernel packages for 2.6.33.1
+#
+# Caveats:
+#
+# Since kernel-package in debian-stable doesn't work with
+# 2.6.33.1, we attempt to patch it in place. This may not be the
+# right thing to do. A possibly better alternative is to install
+# a later version of kernel-package, although that could potentially
+# cause problems with upgrades, etc..
+#
+# The patch to tun.c is a workaround rather than a real fix.
+
+
+# Season to taste
+# export PATH=/usr/lib/ccache:$PATH
