 %description
 Percona Binary Log Server is a command-line utility that acts as an enhanced version of mysqlbinlog in --read-from-remote-server mode. It serves as a replication client and can stream binary log events from a remote Oracle MySQL Server / Percona Server for MySQL both to a local filesystem and to a cloud storage (currently AWS S3). The tool is capable of automatically reconnecting to the remote server and resuming operations from the point where it was previously stopped.
