Both modules are in MonetDB5/src/modules/mal/{bpm.mx,crackers.mx}
The former is under active development. It uses an internal structure
with import/export to BATs as part of the session startup/exit.
The latter is currently subject to reduction and cleanup to improve
re-user and maintenance. It uses an AVL tree to keep a catalog of
routing information in memory.
