%description
The Arm ASTC Encoder (astcenc) is a command-line tool for compressing and
decompressing images using the Adaptive Scalable Texture Compression (ASTC)
data format. The ASTC compressed data format, developed by Arm and AMD, has
been adopted as an official extension to the OpenGL, OpenGL ES, and Vulkan
graphics APIs.
