This directory contains one file for each service.
Each file specifies for how many hours you will keep binlogs for.

Specifically, the command that is run is:
	PURGE BINARY LOGS BEFORE DATE_SUB(now(), interval $time HOUR);"
where time is the number specified in the file.

If the file does not exist, the init script will create it (with a default
of 48 hours I believe).
