# Maxbinlogcheck, the MySQL/MariaDB binlog check utility
# Overview
Maxbinlogcheck is a command line utility for checking binlogfiles downloaded by MariaDB MaxScale binlog router or the MySQL/MariaDB binlog files stored in a database server acting as a master in a replication environment.

It may optionally truncate binlog file.
