       pwi2xsf - convert the pw.x input file to XSF format

SYNOPSIS

       pwi2xsf [-r] file

DESCRIPTION

       pwi2xsf  extracts  the  atomic  structure from pw.x input file and prints the XSF formated
       structure data  to  standard  output.   It  is  a  utility  program  of  xcrysden  package
       (http://www.xcrysden.org/)   and   XSF   is   the   native   xcrysden   structure   format
       (http://www.xcrysden.org/doc/XSF.html).

       If file is specified as "-" then standard input is read.

OPTION

       -r  For old pw.x versions < 1.2  one  must  spefify  the  ityp-->nat  conversion  and  the
           corresponding data are writen to file nuclei.charges. The -r flag deletes this file as
           to force new ityp-->nat specification.
