Shorai

Shorai is an amazing OS that will bring world peace, cure cancer, and have <20 ms audio latency.

Building

Requirements:

the master branch of rust
GNU binutils cross-compiled for i586-elf (the instructions at the OSDev Wiki Cross-Compiler page can be very helpful)
nasm (2.0 or greater)
mkisofs, from cdrtools
a copy of stage2_eltorito from GRUB legacy in the tools/boot/grub/ directory (see the relevant OSDev Wiki page)

For running it, you'll also need an x86 emulator (I'm using QEMU)

To build it, make should be enough. To run it, simply make run.
