2 # SFA Configuration Info
4 # This module holds configuration parameters for SFA. There are two
5 # main pieces of information that are used: the database connection and
6 # the PLCAPI connection
10 # SFA uses a MYSQL database to store records. This database may be
11 # co-located with the PLC database, or it may be a separate database. The
12 # following parameters define the connection to the database.
14 # Note that SFA does not access any of the PLC databases directly via
15 # a mysql connection; All PLC databases are accessed via PLCAPI.
25 Parse the bash/Python/PHP version of the configuration file. Very
26 fast but no type conversions.
