      "DOLFIN is a computational framework for finding numerical
solutions to problems described by differential equations.  Numerical
models in DOLFIN are constructed using general families of finite
elements.  Data structures are provided for discretizing the governing
system on a computational mesh.  A compact syntax, similar to
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.

Gmsh with the versatility of Python.  The package generalises many of
the methods and functions that comprise the Gmsh Python API.  In this
way the meshing of complex geometries using high-level abstractions is
made possible.  The package provides a Python library together with a
command-line utility for mesh optimisation.")

    (description "@code{python-dolfin-adjoint} is a solver of
differential equations associated with a governing system and a
functional of interest.  Working from the forward model the solver
automatically derives the discrete adjoint and tangent linear models.
These additional models are key ingredients in many algorithms such as
data assimilation, optimal control, sensitivity analysis, design
optimisation and error estimation.  The dolfin-adjoint project
provides the necessary tools and data structures for cases where the
forward model is implemented in @code{fenics} or
