!
! writes PWSCF data for postprocessing purposes in XML format using IOTK lib
! Wave-functions are collected and written using IO_BASE module.
!
! input: namelist "&inputpp", with variables
! prefix prefix of input files saved by program pwscf
! outdir temporary directory where files resides
! pp_file output file. If it is omitted, a directory
! "prefix.export/" is created in outdir and
! some output files are put there. Anyway all the data
! are accessible through the "prefix.export/index.xml" file which
! contains implicit pointers to all the other files in the
! export directory. If reading is done by the IOTK library
! all data appear to be in index.xml even if physically it
! is not.
! uspp_spsi using US PP if set .TRUE. writes S | psi >
! and | psi > separately in the output file
! single_file one-file output is produced
! ascii ....
!
! pseudo_dir pseudopotential directory
! psfile(:) name of the pp file for each species
