-Upgrading from 0.3 or 0.4
-=========================
-If you are upgrading from versions 0.3 or 0.4 of SquirrelMail, you can use this
-guide to make the transition a bit smoother.  If you have been using a previous
-version (0.1 or 0.2), it is suggested that you just start from scratch and

 1.  Backups

-Make a backup of your current SquirrelMail directory.  If you use "cp", be sure
-to use the "-Rp" options.  -R means recursive, and -p will save the permissions
-in the directory.  In this example, we assume that your httpd document directory
-is /home/httpd/html.
