This is experimental software. Try it out. If something doesn't work, open an
issue. I can't guarantee I'll be able to fix it though.

Programs require root to use this library directly.

You also need libx86, this seems to be a decent fork of it, if you need
something up to date: https://gitlab.archlinux.org/grawlinson/libx86

This fork gets rid of the helper kernel module, which historically allowed
this library to be used by applications without root privileges. My reasoning
is that kernel modules are not very maintainable, because the Linux kernel
sources aren't very stable.

Instead, I recommend one make a setuid daemon that uses unix sockets or a
user-accessible section of shared memory, which would be much more
maintainable, and could still be decent in speed if done right, I reckon.
