description         tiniest x86-64-linux emulator

long_description    \
    ${name} is a virtual machine that runs x86-64-linux programs on different \
    operating systems and hardware architectures. It's designed to do the \
    same thing as the qemu-x86_64 command, except that it is smaller, runs on \
    any POSIX platform, runs 2x faster than qemu-x86_64 on some benchmarks, \
    and is also faster at running ephemeral programs such as compilers.
