# This script generates a shell script to perform a wiki farm upgrade (to 1.9.3)

# It assumes the presence of "upgrade.list" which is a tab-delimited file 
# containing two tab-delimited fields for each wiki: 
#   1) directory/database suffix
#   2) pretty url (from $wgArticlePath)

# Specifically, the script
# -loops through list of wikis
# -removes old symlinks and creates new ones
# -creates a new LocalSettings.php file based on the template found in the "01" wiki directory
# -runs the upgrade.php script
# -runs the rebuildall.php script

$ts = `date "+%y%m%d"`;
chomp($ts);
