%description

NBD is a protocol for accessing block devices (hard disks and

disk-like things) over the network.

nbdkit is a toolkit for creating NBD servers.

The key features are:

* Multithreaded NBD server written in C with good performance.

* Minimal dependencies for the basic server.

* Liberal license (BSD) allows nbdkit to be linked to proprietary

  libraries or included in proprietary code.

* Well-documented, simple plugin API with a stable ABI guarantee.

  Lets you to export "unconventional" block devices easily.

* You can write plugins in C or many other languages.

* Filters can be stacked in front of plugins to transform the output.

'%{name}' is a meta-package which pulls in the core server and a

useful subset of plugins and filters with minimal dependencies.

If you want just the server, install '%{name}-server'.

To develop plugins, install the '%{name}-devel' package and start by

reading the nbdkit(1) and nbdkit-plugin(3) manual pages.
