 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.
