This directory contains ODE-related things that have been generously contributed by ODE's users. Why is this stuff here and not integrated into the main ODE source tree? There may be several reasons: * The author(s) and ODE maintainers(s) may not have had time to do the job. * It may not be finished. * It may contribute functionality that is useful but not considered to be part of ODE's core. No guarantees are made about the code in this directory - it may not be documented, it may not have been tested, and it may not even compile for you. Each package has its own subdirectory, with a README file in that directory explaining what the package is.
