YAC is a Web counter and logger written in Perl. It counts only "real" visits, meaning that it increases the counter only if there was no request from the same IP within one hour, but logs every page hit. It has 3 output modes and a configurable minimum number of digits displayed. To avoid corrupt data it uses flock for all file operations.
