tag:         tip

files:       LICENCE ROADMAP
description:
Added GPLv3 licence file.

Are there any reasons we have to use LGPL in the future?
I guess UFL being GPL infects many other fenics projects.
Until UFL is required by other FEniCS projects, it doesn't
matter.

merge scripts like ufl-analyse, ufl2latex etc. into one,
with more flexible usage options.

Added some local sandbox test files (nothing to see).
