Updating BugPort
   When updating BugPort, you do not want to overwrite your existing
   conf/config.conf file (or your .htaccess file, if you have one).

   Here is a series of steps that you can use to update BugPort
   without overwriting conf/config.conf.

   Extract the latest BugPort tar.gz to a directory.
      *NIX: tar -zxf bugport-[version].tar.gz

   Change to the extracted directory
      *NIX: cd [bugport-version]

   Copy conf/version.txt to [bugport-home]/conf/version.txt
      *NIX: cp conf/version.txt [bugport-home]/conf/version.txt

   Copy conf/configuration.php to [bugport-home]/conf/configuration.php
      *NIX: cp conf/configuration.php [bugport-home]/conf/configuration.php

   Recursive copy php to [bugport-home]
      *NIX: cp -R php [bugport-home]

   Recursive copy php_classes to [bugport-home]
      *NIX: cp -R php_classes [bugport-home]

   Recursive copy images to [bugport-home]
      *NIX: cp -R images [bugport-home]

   Recursive copy system/ [bugport-home]
      *NIX: cp -R system/ [bugport-home]/system

When upgrading BugPort installations before 1.088 to 1.089 or higher,
you will need to run the SQL statement in the included create_config_table.sql file.

When upgrading BugPort installations before 1.104 to 1.05 or higher,
you will need to run the SQL statement in the included alter_user_table.sql.

When upgrading BugPort installations before 1.133 to 1.134 or higher,
you will need to add the $attachmentDirectory variable to your config.php. 
You will then need to move all dirs/files from your existing bugport/files/ 
directory into your new attachments directory.
