Apso is a framework for adding secrecy to
distributed version control systems by creating
encrypted versions of repositories. This makes it
possible to keep repositories in hostile hosts.
Apso supports pluggable version control systems
and cryptographic libraries.
Spartns is a sparse tensor representation library
for Common Lisp. Tensors are a generalization of
vectors and matrices for any number of dimension.
Spartns is fast and flexible, allowing different
dimensions to be represented in different ways.
