 The software will likely work on any Unix-like systems but we limit our testing and support to a fixed set of platforms.
 Patches may be accepted from developers who test on other operating systems.

 We have a baseline platform which is what we are using for integration testing and deployments.
 For each product, we also have a number of other platforms which are regularly tested by our continuous integration system to enhance portability.
