1) The line containing Haman grid parameters must be completed by
   an information about the spin-orbit format of the pseudopotential.
   So, one replaces
   2.508991628593723E-4  0.0125           r1,al
   by
   2.508991628593723E-4  0.0125  2        r1,al,pspso

   pspso is 1 for non spin-orbit (optional),
            2 for spin-orbit


2) The lines describing the number of projectors and some of their
   characteristics must be duplicated, as soon as l/=0.
   The number of projectors must be 2.

   So, one replaces

3) The pseudopotentials and pseudowavefunctions are then entered,
   in the order  s, p1/2, p3/2, d3/2, d5/2, f5/2, f7/2.


4) The local potential is specified by lloc with the following
   values:
   lloc=0  refers to the s potential
   lloc=1  refers to the p3/2 potential
   lloc=2  refers to the d5/2 potential
   lloc=3  refers to the f7/2 potential
   lloc=-1 refers to the p1/2 potential
   lloc=-2 refers to the d3/2 potential
   lloc=-3 refers to the f5/2 potential
