makezonefile - create config file for bind
=head1 SYNOPSIS
makezonefile
=head1 DESCRIPTION
makezonefile reads from STDIN a list of domains and
their assoziated nameservers; one domain per line, the primary, the nameservers
seperated by whitespace.
Example:
sigint.net 82.94.251.194 asteria.debian.or.at. seppia.noreply.org.
theremailer.net 195.244.237.84|213.239.201.102 asteria.debian.or.at.
vanderheide.ca 64.26.156.90 asteria.debian.or.at.
First column is the domain in question, second is the primary or primaries
separated by a pipe symbol, the rest are the nameservers
For each domain it will then look whether this host's name (as configured in
the @THISNAMES variable) appears in the list of nameservers and if that is the
case add a slave entry to the file hardcoded in the script.
Afterwards a bind9 reload will be issued.
The script is typicalle called from ssh (using authorized keys with command=script).
