description of boundaries for file rotation.

If all fields are None the file will never be rotated. Any field set to Some will cause rotation to happen when that boundary is crossed. Multiple boundaries may be set. Log rotation always causses incrementing rotation conditions (e.g. size) to reset.

The condition keep is special and does not follow the rules above. When a log is rotated keep is examined and logs that do not fall under its instructions are deleted. This deletion takes place on rotation only, and so may not happen. The meaning of keep options are:

• `All -- never delete
• `Newer_than span -- delete files with a timestamp older than Time.sub (Time.now ()) span. This normally means keeping files that contain at least one message logged within span. If span is short enough this option can delete a just rotated file.
• `At_least i -- keep the i most recent files

WARNING: The rotating file functionality of Log is the most poorly tested, and in many ways the most complex. Before using this mode in anger you should test failure cases carefully.
