# Script for adding and dropping ser MySql tables
#
# TO-DO: update_structures command for migriting to new
#        table definitons
# USAGE: call the command without any parameters for info
#
# 2003-01-21 changed SILO table definition, by dcm
#
# History:
# 2003-03-12 added replication mark and state columns to location (nils)
# 2003-03-05: Changed user to username, user is reserved word (janakj)
# 2003-01-26 statistics table introduced (jiri)
# 2003-01-25: Optimized keys of some core tables (janakj)
# 2003-01-25: USER_ID changed to user everywhere (janakj)
# 2003-01-24: Changed realm column of subscriber and pending
#             tables to domain (janakj)
# 2003-04-14  reinstall introduced (jiri)
# 2004-07-05  new definition of table silo (dcm)
