It's still there in share/affine (written by Bill Schelter). The CVS
version is currently broken (mainly because of the sloop -> loop
change). The version contained in the last stable release is supposed
to contain some unspecified but reasonable amount of working stuff.
If you use the stable version try `load("affine.lisp");'. Probably,
this won't work because of some brain-dead logical-pathname stuff of
mine. Plan B: Batch a file containing the following
load("affine/compat");
load("affine/amacros");
load("affine/dummy-gc");
load("affine/polybas");
load("affine/sparsemat");
load("affine/aquotient");
load("affine/new-rat");
load("affine/polya");
load("affine/ndotsimp");
load("affine/polyb");
load("affine/polysmp");
load("affine/sub-proj");
load("affine/polyc");
load("affine/polyd");
load("affine/sheafa");
load("affine/sheafb");
load("affine/sheafc");
load("affine/dim-3");
load("affine/modsimp");
