-# Geniwrapper uses a MYSQL database to store records. This database may be
-# co-located with the PLC database, or it may be a separate database. The
-# following parameters define the connection to the database.
-#
-# Note that Geniwrapper does not access any of the PLC databases directly via
-# a mysql connection; All PLC databases are accessed via PLCAPI.
