 To include this custom header, we now have to modify the main logwatch Perl script ''logwatch.pl''.  To help remember which machines have up-to-date kernels, we want logwatch to assist us by printing the kernel-version in the header.  Using a Gentoo example, add the bold / red lines to '''/usr/sbin/logwatch.pl''':
     output( $index_par, "\n ################### Logwatch $Version ($VDate) #################### \n", "line");

+There are three basic customizations we often perform:
 # increase the header-information with machine-specific info (hardware, admininstrator(s), usage, etc):
 # adjust the order of the information - we care very much about disk-usage, and prefer it ''first''
 Start by ensuring logwatch is actually installed!  A mail-transport agent (MTA) like Postfix or nullmailer must be installed and working (to receive the daily logwatch summary).
