! This program writes the structure and wavefunction to a binary file
! (with extension pwc) read by critic2. At present, this is used
! in combination with the output of wannier90 in the calculation of
! delocalization indices via maximally localized Wannier functions
! (
! Preferred use: with norm-conserving pseudos, since critic2 will not
! know about the transformation near the atoms. Some notes:
! - The density in critic2 won't match exactly the one generated by
! pp.x in general because QE symmetrizes the contributions in
! reciprocal space (see the sym_rho subroutine in
! PW/src/symme.f90). critic2 will not do this, so the densities will
! be slightly different, but nothing too bad in general. If you
! still feel uneasy about it, use nosym=.true. in the calculation.
! - Non-colinear case not supported.
! - Right now, pw2critic only works in serial mode (no mpirun xx)
! and the SCF calculation needs to be run with wf_collect=.true.
! Input: only one namelist (&inputpp) with variables:
! - outdir - the output directory.
! - prefix - the prefix for the SCF calculation.
! - seedname - the prefix for the generated pwc file
! - smoothgrid - if .true., write the smooth grid dimensions.
! (default:.false.)
! TODO: handle parallelization.
