    (description "The FEniCS Form Compiler (FFC) is a compiler for
finite element variational forms.  From a high-level description of
the form, it generates efficient low-level C++ code that can be used
to assemble the corresponding discrete operator (tensor).  In
particular, a bilinear form may be assembled into a matrix and a
linear form may be assembled into a vector.  FFC may be used either
from the command line (by invoking the @code{ffc} command) or as a
Python module (@code{import ffc}).

solutions to problems described by differential equations.  Numerical
models in DOLFIN are constructed using general families of finite

mathematical notation, is made available for defining function spaces
and expressing variational forms.  Interfaces to specialized matrix
solvers are provided for solving the resultant linear systems.

    (description
     "@code{fenics} is a computing platform for solving general classes of
problems that involve differential equations.  @code{fenics} facilitates
access to efficient methods for dealing with ordinary differential
equations (ODEs) and partial differential equations (PDEs).  Systems of
equations such as these are commonly encountered in areas of engineering,
mathematics and the physical sciences.  It is particularly well-suited to
problems that can be solved using the Finite Element Method (FEM).

@code{fenics} is the top level of the set of packages that are developed
within the FEniCS project.  It provides the python user interface to the
FEniCS core components and external libraries.")

    (description "@acronym{SUMO, Simulation of Urban MObility} is a traffic
simulation package designed to handle large road networks and different modes
of transportation -- including road vehicles, public transport and pedestrians.
Included with SUMO is a wealth of supporting tools which automate core tasks
for the creation, the execution and evaluation of traffic simulations,
such as network import, route calculations, visualization and emission
calculation.  SUMO can be enhanced with custom models and provides various
APIs to remotely control the simulation.")
