'bfc' is a small, fast, self-contained, optimizing Brainfuck compiler for *nix
-on Intel x86-64. Currently supported targets are Linux and OpenBSD.
+on Intel x86-64.
Also included are several interpreters in various states of sophistication that
document my progress as I was writing this, from the simplest approach to an
optimizing JIT compiler.
It's pretty easy to retarget the compiler, it just means redoing half the work.
-The compiler itself is platform agnostic.
+Thanks to the unified ABI, adding support for another flavour of *nix only means
+changing the syscall numbers. The compiler itself is platform agnostic.
