synopsis:           Haskell bindings to WebGPU Dawn for GPU computing and graphics
description:
  This package provides Haskell bindings to Google's Dawn WebGPU implementation,
  enabling GPU computing and graphics programming from Haskell. It wraps the
  gpu.cpp library which provides a high-level C++ interface to Dawn.
