Brainfuck compiler and BASIC transpiler for the Commodore 64

============================================================

This compiler runs on the Commodore 64 and emits either C64 machine

code directly, or C64 BASIC. The memory region to use as the Brainfuck

memory and also as the location of the resulting program is

configurable.

Limitations

-----------

* The `,` instruction for input is not supported (it is ignored by the

  compiler)

  

* A maximum of 20 loops can be nested in each other

* Only 256 cells available. Doing a `<` on cell 0 wraps the pointer

  around to cell 255; similarly for `>`.

* There's no check in the compiler to make sure no important bits of

  the RAM is overwritten. For example, using the right memory and

  program base addresses, you can get overlap between the two. You can

  even use a program base address that results in the compiler

  overwriting itself as it emits the results of the compilation.
