Stalin∇ is a brutally optimizing compiler for the VLAD language, a pure dialect of Scheme with first-class automatic differentiation operators.

Written by Jeffrey Mark Siskind, with Barak A. Pearlmutter doing a little cheerleading.

Requires a Scheme compiler and the QobiScheme infrastructure.

cp stalingrad /usr/local/bin/

Enjoy!
