+  List of servers for which a preseed file should be created. Each item in
+  this list defines options for a single server. The options are as follows:
+
+  **name** (string, mandatory)
+    Name associated with the server. This name is used in the preseed

+
+  **keymap** (string, mandatory)
+    Keymap.
+
+  **network_interface** (string, mandatory)
+    Name of network interface (for example *eth0*) that should be
+    configured.

+    additional options needs to be specified.
+
+  **network_ip** (string, mandatory if **network_auto** if *False*)
+    IP address for the server network interface.
+
+  **network_netmask** (string, mandatory if **network_auto** if *False*)
+    Netmask for the server network interface.
+
+  **network_gateway** (string, mandatory if **network_auto** if *False*)
+    Default gateway for the server.
+
+  **network_dns** (string, mandatory if **network_auto** if *False*)
+    Comma-separated list of DNS servers.
+
+  **network_hostname** (string, mandatory if **network_auto** if *False*)
+    Server hostname.
+
+  **network_domain** (string, mandatory if **network_auto** if *False*)
+    Server domain.
+
+  **mirror_hostname** (string, mandatory)
+    Resolvable hostname of FQDN where the Debian apt repositories can be
+    found. Only HTTP mirrors are supported.
+

+
+
+Examples
+~~~~~~~~
+
+Here is an example configuration for a preseed file for two servers, one with
+automatic and one with manual network configuration:
