Subject: frontend: Allow use of new zone machinery.
X-Git-Url: https://git.distorted.org.uk/~mdw/zone/commitdiff_plain/122041a01dd0473d0fa603ba59c58bbe9d203fa1

New options --subnet declares preferred subnets and --directory sets an
output directory.  Also --feature inserts a keyword into *features* for
use by #+/#- reader macros in zone files.
