# `luajit` and `lua54` are MUTUALLY EXCLUSIVE — they select mlua's
# mutually-exclusive Lua backends. `--all-features` enables both and CANNOT
# build; the `mlua-sys` build script errors ("You can enable only one of
# the features: …") before this crate compiles, so pmacs can't preempt it
# with a friendlier message — the fix is to build one flavor. See the
