# # I maintain this because:
# Arch version patch script does not apply consistently
# Arch version lacks ath9k, bdver2, greysky2, and raid6 patches
# Arch version lacks ck patches
# Arch version allows SEED, SM3, SM4, and Streebog
# Arch version is 300 Hz
# Arch version supports Intel ME
# Arch version is not configured for openrc
# Arch version builds docs using python and graphviz
# Arch version uses git
