From the README file:
Licensing for the current version of sarah is quite simple: I (Matthew
Pounsett) retain all rights to this code. Anyone is free to use sarah, but it
may not be redistributed either in its original or any modified form without
the permission of the author (me). A more reasonable license will be
distributed with later versions of sarah (probably with the first non-beta
release).
Sarah is a program which is used to trim, rotate, archive and delete log
files. It is meant to run periodically out of cron, determining what to do
based on a configuration file.
