### Concept ###

Recognize the importance of balancing the need
to keep software up-to-date while minimizing the impact on a production
system. Dragonfly and NetBSD use pkgsrc which provides utilities for
determining which installed software is out-of-date. FreeBSD provides
pkg\_version and third-party utilities are also available which integrate
with the BSD package managers.
