# About {#About}

HWSD is a cross-platform library, designed to run on any modern
operating system, including all Unix variants and the Windows operating
system.  Zeroconf support in Lunchbox is required for the DNS_SD module
and applications.

HWSD uses CMake and [Buildyard](https://github.com/Eyescale/Buildyard)
to create a platform-specific build environment. The following platforms
and build environments are tested:

* Linux: Ubuntu 14.04, RHEL 6.5 (Makefile, i386, x64)
* Windows: 7 (Visual Studio 2008, i386, x64)
* Mac OS X: 10.8 (Makefile, i386, x64)

Technical questions can be posted to the eq-dev Mailing List, or
directly to info@equalizergraphics.com.

Commercial support, custom software development and porting services are
available from [Eyescale](http://www.eyescale.ch). Please contact
