 purge-old-kernels - remove old kernel and header packages from the system
 
 .SH SYNOPSIS
-\fBpurge-old-kernels\fP [--keep N] [--quiet] [*]
+\fBpurge-old-kernels\fP
 
 .SH DESCRIPTION
-This program will remove old kernel and header packages from the system, freeing disk space.  It will never remove the currently running kernel.  By default, it will keep at least the latest 2 kernels, but the user can override that value using the --keep parameter.  Any additional parameters will be passed directly to \fBapt-get\fP(8).
+This utility is now deprecated.  The functionality it used to provide should be integrated into \fIapt\fP(8).
 
-The --quiet option is useful for cronjobs, to ensure silence messages when there's nothing new to do.
+If you still have old kernels lying around after this, please file a bug against apt: https://bugs.launchpad.net/ubuntu/+source/apt/+filebug
 
 This program requires administrative access.
 
 .SH EXAMPLE
 
-sudo purge-old-kernels --keep 3 -qy
