This is a very small Scheme system designed to run on small
microcontrollers, currently the PIC microcontroller.

It consists of

* a bytecode compiler which compiles Scheme source code to bytecode.
  The bytecode compiler is run using the Gambit-C Scheme system,
  usually on a PC/workstation.

* a bytecode interpreter which can be either compiled to run on a
  microcontroller, or to be run on some common operating systems, at
  least GNU/Linux (Windows support hasn't been tested in a while,
  though, and especially the networking part might not work out of the


1. Install the dependencies:

  * Gambit-C: needed to run the bytecode compiler.

  * libpcap: optional, to test networking on PC's (GNU/Linux)
    Be sure to also install the package containing the headers
    (libpcap-dev or similar).
    (TODO: add to makefile somehow)

2a. Targetting a PC/workstation for testing:

  * Build the VM: run

  * Compile and run a Scheme program: run
     ./p schemefile-without-suffix

2b. Compile and run a Scheme program on PIC:



  * S3 (Small Scheme Stack) : A Scheme TCP/IP Stack Targeting Small
    Embedded Applications

  * Slides from the presentation given at the 2008 Workshop on Scheme
    and Functional Programming

 and maybe you find the papers about the BIT and PICBIT systems
 interesting, which have been written before PICOBIT and share some
 common concepts:
