Extra info and code examples

cereal provides a framework to easily set up and maintain automated, timestamped logs of serial lines, while simultaneously allowing end user access to them. This is probably most useful for providing automated, logged access to remote serial consoles. cereal can control an arbitrary number of independently monitored and logged lines. Direct access to the monitored lines is allowed only to a specific user (who doesn't necessarily otherwise have access to the direct serial line), but logs can be made available to any group. Logs are rotated automatically and their total space can be limited in size.
