-python-ifupdown2
-================
-
-This package is a replacement for the debian ifupdown package.
-It is ifupdown re-written in python. It maintains the original ifupdown
-pluggable architecture and extends it further.
-
-The python-ifupdown2 package provides the infrastructure for
-parsing /etc/network/interfaces file, loading, scheduling and state
-management of interfaces.
-
-It dynamically loads python modules from /usr/share/ifupdownmodules (provided
- by the python-ifupdown2-addons package). To remain compatible with other
-packages that depend on ifupdown, it also executes scripts under /etc/network/.
-To make the transition smoother, a python module under
-/usr/share/ifupdownmodules will override a script by the same name under
-/etc/network/.
-
-It publishes an interface object which is passed to all loadble python
-modules. For more details on adding a addon module, see the section on
-adding python modules.
-
-
-pluggable python modules:
-=========================
-Unlike original ifupdown, all interface configuration is moved to external
-python modules. That includes inet, inet6 and dhcp configurations.
-
-A set of default modules are provided by the python-ifupdown2-addons deb.
-
-python-ifupdown2 expects a few things from the pluggable modules:
-- the module should implement a class by the same name
-- the interface object (class iface) and the operation to be performed is
- passed to the modules
-- the python addon class should 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
- 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).
-
-Example: Address handling module /usr/share/ifupdownaddons/address.py
-
-
-build
-=====
-- get source
-
-- install build dependencies:
- apt-get install python-stdeb
- apt-get install python-docutils
-
-- cd <python-ifupdown2 sourcedir> && ./build.sh
-
- (generates python-ifupdown2-<ver>.deb)
-
-install
-=======
-
-- remove existing ifupdown package
- dpkg -r ifupdown
-
-- install python-ifupdown2 using `dpkg -i`
-
-- or install from deb
- dpkg -i python-ifupdown2-<ver>.deb
-
-- note that python-ifupdown2 requires python-ifupdown2-addons package to
- function. And python-ifupdown2-addons deb has an install dependency on
- python-ifupdown2

+Description: Network Interface Management tool similar to ifupdown
+ ifupdown2 is ifupdown re-written in Python. It replaces ifupdown and provides
+ the same user interface as ifupdown for network interface configuration.
+ Like ifupdown, ifupdown2 is a high level tool to configure (or, respectively
+ deconfigure) network interfaces based on interface definitions in
+ /etc/network/interfaces. It is capable of detecting network interface
+ dependencies and comes with several new features which are available as
+ new command options to ifup/ifdown/ifquery commands. It also comes with a new
+ command ifreload to reload interface configuration with minimum
+ disruption. Most commands are also capable of input and output in JSON format.
+ It is backward compatible with ifupdown /etc/network/interfaces format and
+ supports newer simplified format. It also supports interface templates with
+ python-mako for large scale interface deployments. See
+ /usr/share/doc/ifupdown2/README.rst for details about ifupdown2. Examples
+ are available under /usr/share/doc/ifupdown2/examples.

+python-ifupdown2
+================
+
+This package is a replacement for the debian ifupdown package.
+It is ifupdown re-written in python. It maintains the original ifupdown
+pluggable architecture and extends it further.
+
+The python-ifupdown2 package provides the infrastructure for
+parsing /etc/network/interfaces file, loading, scheduling and state
+management of interfaces.
+
+It dynamically loads python modules from /usr/share/ifupdownmodules (provided
+ by the python-ifupdown2-addons package). To remain compatible with other
+packages that depend on ifupdown, it also executes scripts under /etc/network/.
+To make the transition smoother, a python module under
+/usr/share/ifupdownmodules will override a script by the same name under
+/etc/network/.
+
+It publishes an interface object which is passed to all loadble python
+modules. For more details on adding a addon module, see the section on
+adding python modules.
+
+
+pluggable python modules:
+=========================
+Unlike original ifupdown, all interface configuration is moved to external
+python modules. That includes inet, inet6 and dhcp configurations.
+
+A set of default modules are provided by the python-ifupdown2-addons deb.
+
+python-ifupdown2 expects a few things from the pluggable modules:
+- the module should implement a class by the same name
+- the interface object (class iface) and the operation to be performed is
+ passed to the modules
+- the python addon class should 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
+ 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).
+
+Example: Address handling module /usr/share/ifupdownaddons/address.py
+
+
+build
+=====
+- get source
+
+- install build dependencies:
+ apt-get install python-stdeb
+ apt-get install python-docutils
+
+- cd <python-ifupdown2 sourcedir> && ./build.sh
+
+ (generates python-ifupdown2-<ver>.deb)
+
+install
+=======
+
+- remove existing ifupdown package
+ dpkg -r ifupdown
+
+- install python-ifupdown2 using `dpkg -i`
+
+- or install from deb
+ dpkg -i python-ifupdown2-<ver>.deb
+
+- note that python-ifupdown2 requires python-ifupdown2-addons package to
+ function. And python-ifupdown2-addons deb has an install dependency on
+ python-ifupdown2
