- tarfs ramdisk
- SMP (multiple cores)
- Hosted toolchain
- mlibc-based usermode libc
- PS/2 keyboard and mouse
- Input API
- Graphics API (basic)
- Mesa port (OpenGL ES1/2/3)
- Coreutils (ls, cat, etc)
- Can run Doom
- Runs on real hardware (somewhat)

Run make bootstrap and wait, it will build the hosted toolchain, ported software, and mlibc.
Typically you'll want to either run make clean run-linux or make clean debug-linux. You can optionally add KVM=1 at the end for faster emulation if your system supports KVM, and SMP=X where X is the amount of virtual CPUs you want it to use.
