The description of Web Log Filter - Play With New Friends
Web Log Filter is a helper utility for people who have huge (Apache) web log files, over a gigabyte in size, and want to be able to analyze these logs in standard web log analysis tools. Web Log Filter runs simple scripts that will rip through a log file at blazing speed and extract just the lines you care about (discarding the rest) and create one or more new log files, which are smaller and more manageable.
