 =head1 SYNOPSIS  
   
 ./CHECKRPMS  
   
 or  
   
 perl CHECKRPMS  
   
 =head1 DESCRIPTION  =head1 DESCRIPTION
   
 This file automates the usage of Martin Siegert's "check-rpms"  Runs Martin Seigert's checkrpms script.  See 
 script.  It runs through a list of possible mirror sites  http://www.sfu.ca/acs/security/linux/check-rpms.html for more information.
 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  
   
 Note that there are no current plans to automate a software upgrade of the  Must be run as root or www.
 kernel.  This step should be performed by a qualified system administrator.

   If there are rpms which need to be installed, please log into

   $checkrpms --update
   
   If there are kernel packages to be installed, use
   
   $checkrpms --update --install-kernel
   
   Keeping your system up to date is very important.
   Ensuring you are using up to date software is a prerequisite for a 
   secure system.
   
 Please visit ftp://$FTPUPDATES  
 and download the RPMS you need.
