module to handle output destined for log files

 Log::Handler is an easy-to-use Perl module designed to handle log files. It's
 possible to define a log level for your programs and control information that
 will be written to the log file. The module handles locking and unlocking of
 the log file according to the operating mode. It can also verify the inode of
 log file, which is useful if log rotation is in use.
