[Pw_forum] epsilon.x

[Emine Kucukbenli]

Dear Dev,
I also have never used this feature of the code but Doc directory has  
useful documents when you need answers: Doc/eps_man.tex
It is clearly stated there that "the non-local contribution due to the  
pseudopotential is neglected. Actually the correction to the matrix  
element that take into account the non-local part of the Hamiltonian  
is not implemented."
So to develop the code for USPP you need to find a way to calculate &  
add these corrections, I guess. You can check epsilon.f90 to learn  
more..
