python-ufl 2017.2.0.0-2 (amd64 binary) in ubuntu cosmic

 UFL (Unified Form Language) is a unified language for definition of
 variational forms intended for finite element discretization. More
 precisely, it defines a fixed interface for choosing finite element
 spaces and defining expressions for weak forms in a notation close to
 mathematical notation. The form compilers FFC and SyFi use UFL as
 their end-user interface, producing UFC implementations as their
 output.
