 DOLFIN is the Python and C++ interface of the FEniCS project for the
 automated solution of differential equations, providing a consistent
 PSE (Problem Solving Environment) for solving ordinary and partial
 differential equations. Key features include a simple, consistent and
 intuitive object-oriented API; automatic and efficient evaluation of
 variational forms; automatic and efficient assembly of linear
 systems; and support for general families of finite elements.
 .
 This is the base package depending on specific dolfin builds. By
 default the version built against the preferred version of PETSc in
 /usr/lib/petsc is selected (with 32-bit indexing, but the
 alternative version (64-bit PETSc) can be selected by setting the
 environment variable PETSC_DIR.
 .
 This is the legacy version of DOLFIN, you may want to install the
 next-generation python3-dolfinx (DOLFIN-X) instead.
