# Notes for llama.cpp:
# 1. Tags are currently based on hash - which will not sort asciibetically.
#    We need to declare standard versioning if people want to sort latest releases.
#    In the meantime, YYYYMMDD format will be used.
# 2. Builds for CUDA/OpenCL support are separate, with different depenedencies.
# 3. NVidia's developer repo must be enabled with nvcc, cublas, clblas, etc installed.
#    Example: https://developer.download.nvidia.com/compute/cuda/repos/fedora37/x86_64/cuda-fedora37.repo
# 4. OpenCL/CLBLAST support simply requires the ICD loader and basic opencl libraries.
#    It is up to the user to install the correct vendor-specific support.
