mkdomains_idn_master

#!/usr/bin/env ruby18
#
# == IDN zone generator

# = Usage:

#   $ mkdomains_idn крутой.домен.рф ...
#
# = What does it do?
#
# - Creates a punycode name from an IDN input
# - Makes a zone file of this name and writes zone stub into it
# - adds zone information to *.conf BIND config file (see config section)
