This is the distribution of the ld1 code for electronic structure 
atomic calculations and pseudo-potentials generation.

The ld1 code, maintained by Andrea Dal Corso (SISSA, Trieste) 
is the result of several additions to the original code by
P. Giannozzi (http://web1.sns.it/~giannozz/software.html) for 
pseudopotential generation. The major additions are:

a) Generation and test of norm-conserving and ultrasoft pseudo-potentials
   with the Rappe-Rabe-Kaxiras-Joannopoulos (RRKJ) recipe
   ( Phys. Rev. B41, 1227 (1990); Phys. Rev. B 44, 13175 (1991) )
b) Generation of fully relativistic pseudo-potentials including 
   spin-orbit coupling.

Input variables are described in file INPUT_LD1.
Directories all-electron/, pseudo-gen/, pseudo-test/, 
contain tests for the three modes of operation, respectively:
all-electron run, pseudo-potential generation, pseudo-potential testing.
