The Nanopass framework for Scheme has moved to its own github group. This one will no longer get updates. You can find the new repo here:

https://github.com/nanopass/nanopass-framework-scheme

There is also a port of this project to Racket, which you can find at:

https://github.com/nanopass/nanopass-framework-racket

Additional information can be found at the nanopass website:

This repositiory contains an R6RS version of the Nanopass Compiler Infrastructure described in [1, 2, 3, 4], along with the beginnings of a test compiler for the library and the rough start to a users guide. The nanopass framework currently supports Chez Scheme, Vicare Scheme, and Ikarus Scheme.
