+=head1 NAME
+
+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 nameservers
+seperated by whitespace.
+
+Example:
+
+ debian.org	murphy.debian.org auric.debian.org ns2.cistron.nl ns.hands.com
+ palfrader.org	gw.frosty-geek.net ns1.3node.com ns.sourcecode.at i-got-this.ns.for-beer.org
+ 3node.com	ns2.3node.com ns1.3node.com
+
+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. Master Nameserver is hardcoded too.
+
+Afterwards a bind9 reload will be issued.
+
+
+The script is typicalle called from ssh (using authorized keys with command=script).
