# Purpose:
#
# The script was designed to transfer categories, forums, users, and posts
# from phpBB 2.0 to XoopsBB 1.0.
#
# Assumptions:
#
# - phpBB 2.0 and XoopsBB 1.0 are installed on the same database
# - if user is in both phpBB an XoopsBB, they have the same user name in
# - XoopsBB 1.0 is currently empty and phpBB 2.0 has contents to transfer
# - phpBB 2.0 tables are prefixed with "phpbb_"
# - XoopsBB 1.0 tables are prefixed with "xoops_bb_"
#
# If the phpBB 2.0 and XoopsBB 1.0 tables are on different databases, please
# do a dump of the phpBB 2.0 tables and add then do a restore to the
# database that contains your XOOPS installation.
#
# If you have users on both systems, make sure that they have the same user
# name in each system before running this script.
#
# If your table prefixes differ, please do a global search on these prefixes,
# replacing them with the correct prefixes for your installation.
#
# Directions:
#
# This script can be executed using phpMyAdmin or from the command line.
# Using phpMyAdmin, you can first click on the name of your database, then
# scroll down until you see "Run SQL query/queries on database". You can either
# cut and paste this script into this area, or locate this script from your
# home machine by pressing the "Browse:" button and then clicking on "Go."
# To run this script from the command line, use the following format:
# MySQL -u<username> -p<password> -h<host> database < phpBB2_XoopsBB_Converter.sql
#
# Notes:
#
# Due to differences in supported functionality between phpBB 2.0 and XoopsBB 1.0,
# some items cannot be converted:
#
# - Polls that accompany topics
# - Topics watch (e-mail alerts when responses are posted)
# - Security by group (groups are copied, but security is translated to indidual users)
#
# Known issues:
#
# - Number of posts is not converted for users that already exist in Xoops
# - If your users have avatars, they will have to reload them
# Preliminary step - clear out Xoops_BB tables
# This is here primarily in case there is an error in the script and you need to execute again.

# else if forum post access = REG or PRIVATE, set forum access to Registered Users Only,
