    Fls is a nearly-POSIX-compliant and libc-less ls that's smaller, faster,
    and prettier than GNU's1. Exa and lsd are both great ls-like Rust programs,
    but they're slower than the system ls and about 10x the code size. Plus you
    can't actually replace your ls with one of them, because some software relies
    on parsing the output of ls. Fls is compatible with those softwares.
