usOOo server scripts

This script is used to unload the current database

# Dump language schema to TGZ tarball. 
#
# We only have postgres utils v8.1 on the server so wildcards in the pg_dump -t option don't work.
# I will add a case selection to limit the table list for the incremental delta dumps
#
 dump_lang() {
  psql="psql -U ooo_oucv_admin $2"
  tables="`echo \"\d\" | $psql | perl -ne \"/(\w+_${1}_\w+)\s+\| table/ && print \\\$1.' ';\"`"
  for t in $tables; do
    pg_dump -i -U ooo_oucv_admin -x -t $t  -a $2 2> /dev/null
  done
}
# Note that for security reasons these tarballs are deleted after transfer

Standard NL configuration

All instances have the same content and essentially symlink everything but the avatars-load, cache and files directories. This means that all image sets and code changes are common to all versions. This includes the specific changes to the French forum that Bidouille requires (and in fact these are enabled by the existence of a specific match parameter that they use.) This all works because all of the forum configuration (such as the selection of the forum's main logo) is maintained in the forum database, and this database is private to each NL forum. In the same way, the individual styles are cached in the database so the Vietnamese forum can tweak its CSS to remove the underlines from links in the database (this is needed because accents in Vietnamese also lie under the letters and an underline can obscure these changing the meaning of the text).

Hence each forum instance has exactly the same structure, excepting the three content directories:
