> +Netmap Compatibility Sample Application
> +=======================================
> +
> +Introduction
> +------------
> +
> +The Netmap compatibility library provides a minimal set of APIs to give
> programs written against the Netmap APIs
> +the ability to be run, with minimal changes to their source code, using
> the DPDK to perform the actual packet I/O.
> +
> +Since Netmap applications use regular system calls, like ``open()``,
> ``ioctl()`` and
> +``mmap()`` to communicate with the Netmap kernel module performing the
> packet I/O,
> +the ``compat_netmap`` library provides a set of similar APIs to use in
> place of those system calls,
> +effectively turning a Netmap application into a DPDK application.
> +
> +The provided library is currently minimal and doesn't support all the
> features that Netmap supports,
> +but is enough to run simple applications, such as the bridge example
> detailed below.

> +Knowledge of Netmap is required to understand the rest of this section.
> +Please refer to the Netmap distribution for details about Netmap.

Just plain text is enough, please remove rst format indicator.
