+# Simple script to generate a deb package for a Linux kernel. All the
+# complexity of what to do with a kernel after it is installed or removed
+# is left to other scripts and packages: they can install scripts in the
+# /etc/kernel/{pre,post}{inst,rm}.d/ directories (or an alternative location
+# specified in KDEB_HOOKDIR) that will be called on package install and
+# removal.
