DRUM (Deep Reader for Understanding Mechanisms) is an IHMC-led project funded by DARPA under the Big Mechanism program.
This git repo is a mirror of the TRIPS drum CVS module. It is updated nightly.
Note that the src/config/lisp/defsystem/defsystem-3.6i/ directory contains a modified, non-standard, non-official version of MK:DEFSYSTEM 3.6i. See the comments near the top of defsystem.lisp in that directory for its copyright notice and license.
