+# = definition: bind::generate
+#
+# Creates a $GENERATE directive for a specific zone
+#
+# == Arguments
+#  $zone:         mandatory - zone name. Must reflect a bind::zone resource
+#  $range:        mandatory - range allocated to internal generate directive.
+#                 Must be in the form 'first-last', like '2-254'
+#  $record_type:  mandatory - must be one of PTR, CNAME, DNAME, A, AAAA and NS
+#  $lhs:          mandatory - generated name (see examples)
+#  $rhs:          mandatory - record target (see examples)
+#  $record_class: optional - incompatible with pre-9.3 bind versions
+#  $ttl:          optional - time tolive for generated records
+#
+# == Examples
+#
+# bind::zone {'test.tld':
+#   zone_contact => 'contact.test.tld',
+#   zone_ns      => 'ns0.test.tld',
+#   zone_serial  => '2012112901',
+#   zone_ttl     => '604800',
+#   zone_origin  => 'test.tld',
+# }
+# ## Generate A records
+# bind::generate {'a-records':
+#   zone        => 'test.tld',
+#   range       => '2-100',
+#   record_type => 'A',
+#   lhs         => 'dhcp-$', # creates dhcp-2.test.tld, dhcp-3.test.tld …
+#   rhs         => '10.10.0.$', # creates IP 10.10.0.2, 10.10.0.3 …
+# }
+# ## Means: dig dhcp-10.test.tld will resolv to 10.10.0.10
+#
+# ## Generate CNAME records
+# bind::generate {'a-records':
+#   zone        => 'test.tld',

+#   record_type => 'CNAME',

+#   rhs         => 'dhcp$',  # creates IP dhcp2.test.tld, dhcp3.test.tld …
+# }
+# ## Means: dig dhcp10.test.tld => dhcp-10.test.tld => 10.10.0.10
+#
+# bind::zone {'0.10.10.IN-ADDR.ARPA':
+#   zone_contact => 'contact.test.tld',

+#   zone_ttl     => '604800',
+#   zone_origin  => '0.10.10.IN-ADDR.ARPA',
+# }
+# ## Generates PTR
+# bind::generate {'ptr-records':
+#   zone        => '0.10.10.IN-ADDR.ARPA',
+#   range       => '2-100',
+#   record_type => 'PTR',
+#   lhs         => '$.0.10.10.IN-ADDR.ARPA.', # 2.0.10.10.IN-ADDR.ARPA …
+#   rhs         => 'dhcp-$.test.tld.', # creates dhcp-2.test.tld …
