Apply equation constraint on DOF

Hi,

I am trying to figure out how I can apply equation constraints on displacement dofs at the boundary of cubic cell.
The goal is eventually to define a module that allows to apply Periodic Boundary conditions on a non-periodic mesh (using interpolation between dofs). Is there any way to add equality constraints on dofs in FEnics/dolfin ?

Thanks!
Yves
