# # I maintain this because:
# Arch version uses eme
# Arch version uses git
# Arch version uses python2
# Arch version uses clang
# Arch version requires signed addons
# Arch version doesn't remove system addons
# Arch version enables debug symbols
# Arch version lacks privacy and security by default
# Arch version uses alternate name which breaks addon packages
