4349. [contrib] kasp2policy: A python script to create a DNSSEC
policy file from an OpenDNSSEC KASP XML file.
4348. [func] dnssec-keymgr: A new python-based DNSSEC key
management utility, which reads a policy definition
file and can create or update DNSSEC keys as needed
to ensure that a zone's keys match policy, roll over
correctly on schedule, etc. Thanks to Sebastian
Castro for assistance in development. [RT #39211]
