-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
-configure your settings as if it was your first install.
-
-NOTE: The new plugin architecture required the use of some functions which are
-not in all versions of PHP4. You will need at least PHP4 beta2. If you need to
-upgrade please go ahead and install the latest release version of PHP4.
-
-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.
