Mini-NDN version 0.1.0 (initial release)
----------------------------------------

Release date: July 15, 2015

Mini-NDN is a lightweight networking emulation tool that enables
testing, experimentation, and research on the NDN platform. Based on
Mininet, Mini-NDN uses the NDN libraries, NFD, NLSR, and tools released
by the `NDN project <http://named-data.net/codebase/platform/>`__ to
emulate an NDN network on a single system.

**Included features**:

-  Run a complete NDN network on a single system

-  Automatic configuration of NLSR to provide a routable NDN network

-  Supports user created NDN applications

-  Create a topology using the included Mini-NDN Edit GUI application

-  Allows individual configuration of NFD and NLSR parameters for each
   node

-  Provides an experiment management framework for easy creation of
   custom networking experiments

-  Uses a simple topology file format to define hosts, links, and
   configuration values

-  Configure network link parameters including bandwidth, delay, and
   loss rate

-  Includes a pre-configured topology file to replicate the NDN testbed
