-B<CHECKRPMS> - automated status report about RPMs on a system
-
-=head1 SYNOPSIS
-
-./CHECKRPMS
-
-or
-
-perl CHECKRPMS
+B<CHECKRPMS> - automated status report about RPMs on a system.
 
 =head1 DESCRIPTION
 
-This file automates the usage of Martin Siegert's "check-rpms"
-script.  It runs through a list of possible mirror sites
-until it finds one with a reasonably good FTP connection.
-
-=head2 Future directions
-
-Eventually, this script may have a simple argument format
-that allows the user to VIEW, DOWNLOAD, or AUTOUPDATE their
-computer.  Or, this script may evolve into an interactive
-series of steps:  For example, there may be questions like this:
-
-=over 4
-
-=item *
-
-Do you want to (D)ownload or (A)utoupdate the RPMs
-in the list above?
-
-=item *
-
-Specify a download location for the RPMs
-(default=/tmp/update_my_rpms/)?
-
-=back
+Runs Martin Seigert's checkrpms script.  See 
+http://www.sfu.ca/acs/security/linux/check-rpms.html for more information.
 
-Note that there are no current plans to automate a software upgrade of the
-kernel.  This step should be performed by a qualified system administrator.
