  Description     : DXT texture compression library

 libsquish is a software DXT texture compression library. It
 implements the 5 DXT flavours and has SIMD support for x86 (SSE) and
 powerpc (Altivec). It can be used (as a much slower software
 fallback) instead of the hardware implementations present on most
 modern graphics chips.

This package is a build-dependency of Cavewhere
(https://github.com/Cavewhere, http://www.cavewhere.com), used because
using the hardware implementations has been unreliable in practice,
and speed is not critical here..
