# # I maintain this because:
# Arch version lacks additional optimization and hardening flags
# Arch version does not use system bullet
# Arch version does not use system recastnavigation
# Arch version cannot be built offline
# Arch version segfaults when loading save games due to -Wp,-D_GLIBCXX_ASSERTIONS
