    e401.  
    Limiting the Size of a Log File</h3>

By default, a log file can grow without bound.  It is possible to
limit the size of the file by specifying the desired limit when
creating a file handler.  When a record is about to be logged and the
file size is greater than the limit, the file is emptied before the
record is logged.  This example creates a file handler with a limit.
