Update of /cvsroot/koha/koha/updater
In directory usw-pr-cvs1:/tmp/cvs-serv4842

Added Files:
Log Message:
Script that will update existing databases, creating any new tables,
adding, modifying or removing any fields from existing tables.

This is in very early stages.  Need to go through and ascertain which
tables and fields need to be added/modified.  Also need to add a "backup"
before any modifications are made.  Thoughts on this are welcome.

--- NEW FILE ---

# This script will check for required updates to the database.  Would also be a
# good idea to offer to do a backup at this time...
