%global _description %{expand:
cuslines (GPUStreamlines) runs DIPY's probabilistic, PTT and bootstrap
direction getters for many seeds in parallel. It picks a CUDA, Metal or WebGPU
backend when one is available and otherwise runs the same kernels on the CPU
through Numba, which is pyAFQ's default tractography path.

This package carries the Numba CPU backend and the kernel sources. The CUDA
backend also needs NVIDIA's cuda-python bindings and the WebGPU backend wgpu,
neither of which is packaged here.}
