Matchbox is an Open Source base environment for the X Window System running on non-desktop embedded platforms such as handhelds, set-top boxes, kiosks and anything else for which screen space, input mechanisms or system resources are limited.

Matchbox consists of a number of interchangeable and optional applications that can be tailored to a specific non desktop platform to enhance usability in a ‘constrained’ environment.
