[plt-scheme] Staapl

Hello folks,

The Staapl project has come to a point where it is ready for public
scrutiny.

http://zwizwa.be/staapl

Staapl is a collection of abstractions for (meta)programming
microcontrollers from within PLT Scheme. The core of the system is a
programmable code generator structured around a functional
concatenative macro language. On top of this it includes a syntax
frontend for creating Forth-style languages, a backend code generator
for Microchip's PIC18 microcontroller architecture, and interaction
tools for shortening the edit-compile-test cycle.

Enjoy!
Tom
