Usage: $progName [options]

This program cleans logs. This script is experimental. Do not run it unless you have talked to Andreas about it. 
The script deletes log lines related to sessions that produce more than 200 lines.

Options:
        -d, --debug                     Used when configuring the log file syntax. See doc.
        --dry-run                       Aggregate but do not store the results.
        --infile                        File input.
        --outfile                       File to output the results.
