optional arguments:
--preferred_year YEAR, --preferred-year YEAR
When a format\'s timestamp does not include a year,
e.g. syslog, use this as the initial year instead of
attempting auto-detection.
--process_archives, --process-archives
Process file entries embedded within archive files,
such as archive.tar and archive.zip. This can make
processing significantly slower.

Skip processing file content within compressed
streams, such as syslog.gz and syslog.bz2.
