+Writing a ifupdown2 addon module
-------
+--------------------------------
+Addon modules are a nice way to add additional functionality to ifupdown2.
+Typically a new addon module will include support for a new network interface
+configuration which is not already supported by existing ifupdown2 addon
+modules.
+
+ifupdown2 addon modules are written in python. python-ifupdown2 package
+comes with default addon modules. All addon modules are installed under
+/usr/share/ifupdownaddons directory.
+
+The center of the universe for an addon module is the 'class iface' object
+exported by the python-ifupdown2 package.
+
+The iface object is modeled after an iface entry in the user provided network
+configuration file (eg. /etc/network/interfaces). For more details see
+the api reference for the iface class.
+
+ifupdown2 dynamically loads a python addon module. It expects the addon module
+to implement a few methods.
+
+* all addon modules must inherit from moduleBase class
+* the module must implement a class by the same name
+* the network interface object (class iface) and the operation to be performed
+  is passed to the modules. Operation can be any of 'pre-up', 'up', 'post-up',
+  'pre-down', 'down', 'post-down', 'query-check', 'query-running'.
+  The module can choose to support a subset or all operations.
+  In cases when the operation is query-check, the module must compare between
+  the given and running state and return the checked state of the object in
+  queryobjcur passed as argument to the run menthod.
+* the python addon class must provide a few methods:
+    * run() : method to configure the interface.
+    * get_ops() : must return a list of operations it supports.
+      eg: 'pre-up', 'post-down'
+    * get_dependent_ifacenames() : must return a list of interfaces the
+      supported interface is dependent on. This is used to build the
+      dependency list for sorting and executing interfaces in dependency order.
+    * if the module supports -r option to ifquery, ie ability to construct the
+      ifaceobj from running state, it can optionally implement the
+      get_dependent_ifacenames_running() method, to return the list of
+      dependent interfaces derived from running state of the interface.
+      This is different from get_dependent_ifacenames() where the dependent
+      interfaces are derived from the interfaces config file (provided by the
+      user).
+    * provide a dictionary of all supported attributes in the _modinfo
+      attribute. This is useful for syntax help and man page generation.
+
+python-ifupdown2 package also installs ifupdownaddons python package
+that contains helper modules for all addon modules.
