+# this script has little to no error checking
+# it is uggly!
+# presented as is , working in test environment,
+# ready for inspction and testing in production environment.

+#note.. did not fully implement privmsgs
+#but left code for it in included file

+#-----------preperation-------------------------------------------------------
+# backup both forum dbs (in the event of failure start fresh . do not attempt salvage or a second execution on damaged db)
+#
+# db1 source
+# db2 target
+# will yeild a forum with the settings of db2 with combined content of both
+#
+# from db1 backup tables:
+# phpbb_users,phpbb_topics,phpbb_forums,phpbb_posts,phpbb_privmsgs,phpbb_privmsgs_to,phpbb_attachments,phpbb_poll_votes,phpbb_poll_options
+#
+# edit the backup tables
+# find and "replace all" add a suffix of _2 (eg. phpbb_users_2,phpbb_topics_2 etc ) to the table names
+# import modified tables into db2
+#
+# db2 is now the working database for the merge
+
+
+
+#---------operation------------------------------------
+#fill in the nessicary db connection info then execute with python.
+
+#this will take some luck
+
+#after sucesfull execution .
+#caches will need to be clered
+#resynch and reset everything (post count users online cache active sessions etc)
+#and permissions will need to be setup or the forums will be invisable to admin and user alike
