/****************************************************************************
 ** TikiWiki Forum Import Tool v1.00                            12/01/2007 **
 ****************************************************************************
 ** Written by Mike Kerr (kerrnel22)
 ** 
 ** This script is for importing the contents of a TikiWiki forum:
 **    - from the same database
 **    - from a different database
 **    - from a different server
 **    - from an SQL dump
 **   
 ** You must have 'tiki_forum_admin' permissions to run this script, due to
 ** the sensitive and invasive nature of this activity.  Forum moderators do
 ** not count.
 **
 ** This tool will not import attachments, or retain state information such
 ** as read counters or posts waiting on moderator approval.
 **
 ** The target forum must already exist on your Tiki installation.  The forum
 ** you select to move will not be recreated.  Only the contents will be
 ** copied.
 **
 ** Roadmap
 ** -------
 ** v1.1 - Allow to migrate phpBB2 (perhaps other forum types) to Tiki forums.
 **
 ** STATE OF THE CODE
 ** -----------------
 ** - Currently only works when importing Tiki forums from an SQL file.
 ** - SQL file dump must be set to escape single quotes with \' instead of ''
 ** - If you get timeout problems, you may need to increase your php.ini
 **   'max_execution_time' to something like 120 or more, depending on the
 **   size of your SQL file.  120 is good for a file around 20Mb.
