    (description "The Open Lighting Architecture is a framework for lighting
control information.  It supports a range of protocols and over a dozen USB
devices.  It can run as a standalone service, which is useful for converting
signals between protocols, or alternatively using the OLA API, it can be used
as the backend for lighting control software.  OLA runs on many different
platforms including ARM, which makes it a perfect fit for low cost Ethernet to
DMX gateways.")
