clinfo is a simple command-line application that enumerates all
possible (known) properties of the OpenCL platform and devices
available on the system.

Inspired by AMD's program of the same name, it is coded in pure C and
it tries to output all possible information, including those provided
by platform-specific extensions, trying not to crash on unsupported
properties (e.g. 1.2 properties on 1.1 platforms).
