#
# Script for adding and dropping Kamailio MySQL tables
#
# History:
# 2006-04-07  removed gen_ha1 dependency - use md5sum;
#             separated the serweb from kamailio tables;
#             fixed the reinstall functionality (bogdan)
# 2006-05-16  added ability to specify MD5 from a configuration file
#             FreeBSD does not have the md5sum function (norm)
# 2006-09-02  Added address table (juhe)
# 2006-10-27  subscriber table cleanup; some columns are created only if
#             serweb is installed (bogdan)
# 2007-02-28  DB migration added (bogdan)
# 2007-05-21  Move SQL database definitions out of this script (henning)
# 2007-05-31  Move common definitions to kamdbctl.base file (henningw)
# 2007-06-11  Use a common control tool for database tasks, like the kamctl
