Hellys Log Lezer,

This program was build to read the log file of a program called DUMeter. It monitors your network usage and creates a log of it. This program would read it and create tables of it so you could easily see what you would use on a daily/monthly/yearly basis. The program is entirely in dutch so it might not be of use to you. I also do not know if DUMeter is still being developed or used.

Check the screenshot page to see what it looks like.
