kBeroFTPD is free software; you may copy it both in source and binary form
(and both), in modified and unmodified versions, as long as the copyright
notice is preserved.
Any products based on kBeroFTPD must have a reference to kBeroFTPD and its
author both in the documentation and, if possible, the program itself.
If you make any changes to the code, you should (but are not absolutely
required to) send them to the author or mailing lists so they can be
included in future releases.
If you make money using kBeroFTPD, you should (but are not required to) send
me a share - free software does not write or maintain itself.
