Cyclone is an experimental Scheme-to-C compiler that uses the Cheney on the MTA technique to implement full tail recursion, continuations, and generational garbage collection.

Getting Started

1. To install Cyclone on your machine for the first time use cyclone-bootstrap to build a set of binaries.

2. After installing you can run the cyclone command to compile a single Scheme file:

    $ cyclone examples/fac.scm
    $ examples/fac
    3628800
   

   And the icyc command to start an interactive interpreter:

    $ icyc
   
                  :@
                @@@
              @@@@:
