+Notes:
+
+It would be nice if some CentOS/Redhat/Slackware/BSD/etc hackers could write
+other types to compliment this one for other OSes. Then we can unite them with a
+__net_bridge type that would call the other types such as this one.
+
+I might add support for vde2 and other linux/BSD virtual network technologies
+when I require them.
+
+If you have such a requirement for Debian derivatives, do not hesitate to
+contact me.

+Simon Walter <simon at explicit dot technology>
+
+
+NAME
+----
+cdist-type__net_bridge_interface_d - Manage network bridges with
+/etc/network/interfaces.d/files
+
+
+DESCRIPTION
+-----------
+Add and remove bridges on a Debian derivative. Does not respect any network
+manager or other userspace software.
+
+The files under /etc/network/interfaces.d/ allow one to add configurations 
+without touching the main /etc/network/interfaces file.
+
+You will need: __package bridge-utils --state present
+
+
+REQUIRED PARAMETERS
+-------------------
+None - defaults may not be suitable!
+
+
+OPTIONAL PARAMETERS
+-------------------
+- name
+    If supplied, use the name and not the object id as the bridge name.
+
+- state
+    Either "present" or "absent", defaults to "present"
+
+- ipaddress
+    Set the IP address of the bridge to static. If not set, defaults to DHCP.
+
+- netmask
+    If ipaddress is in CIDR notation, this is not required.
+
+- broadcast
+    If ipaddress is in CIDR notation, this is not required.
+
+- force
+    This type manages bridges with files in /etc/network/interfaces.d/. When
+    an interface does not have a correspoding file in
+    /etc/network/interfaces.d/, it is assumed that it is not managed by cdist.
+    This flag will override the default to exit when no file is found.
+    It will also recreate the interface and file even if both exist. This is a
+    good way to make sure that you've updated to new values.
+
+EXAMPLES
+--------
+
+--------------------------------------------------------------------------------
+::
+# Set up a bridge with a static IP address
+__net_bridge_interface_d br0 --ipaddress 10.1.1.1 --netmask 255.255.255.0 \
+--broadcast 10.1.1.255 --force-update
+
+# Remove bridge "br0"
+__net_bridge_interface_d br0 --state absent
+
+# Making sure that the necessary packages are installed first
+require="__package/bridge-utils" __net_bridge_interface_d br0 \
+--ipaddress 10.1.1.1 --netmask 255.255.255.0 --broadcast 10.1.1.255
