tozone \- convert ndb database to a zone file
.SH SYNOPSIS
.B ndb/tozone
[
.B -dg
] [
.B -f
.I dbfile
] [
.I zone...
]
.SH DESCRIPTION
Convert a network database file to a zone file
for bind interoperability.  Standard name compression
is applied and glue for subordinate zones is automaticly
generated.  (Glue may be supressed with
.BR -g ).
Each soa in the input file (default
.BR /lib/ndb/local )
is converted into a zone.  Reverse zones (including
classless RFC2317-style zones) are automaticly generated
given an soa record.  The databases may be specified
with the
.B -f
flag.  Arguments limit the zones generated to 
the specified zones.

.SH BUGS
Ndb's structure makes it difficult to be precise about which
records belong to which zones.  In contrast to a `/' in a path,
a `.' in a dns name is not always a zone boundary.
Zones are greedy; a single soa with a dom of `.' would include
all names.
