This script can be used to mostly reconstruct a logfile from the data in the database. Of course, any non-stored data will be lost. This uses the logfile format parameter to determine how to format the line, so the end result should be pretty close to the original logfile, but may vary slightly. However, the resulting output should be good enough to be reimported back into OWS.
