Download DIRDIF into your local dirdif directory 
---->  for MSDOS: cd C:\dirdif 
---->  for unix: cd $HOME/dirdif
Thereafter, proceed as described in file 'implem.txt' for MSDOS or unix.

Download DIRDIF via www.crystallography.nl
------------------------------------------

  goto : www.crystallography.nl
  click: software  
  click: DIRDIF
  click: ... to get DIRDIF ....
  click: download.txt [ to read this file ]
         ---->  for MSDOS:  click: MSDOS

  Download [ drag or copy/paste ] dirdif.zip into your local directory. 

Download DIRDIF by ftp
----------------------
  
  Note for MSDOS users: open an MSDOS-window for the following 
         ftp instructions. When not familiar with MS-DOS, get dirdif via
         www.crystallography.nl  [ and read file msdos.txt ! ].

  ENTER: ftp ftp.sci.kun.nl  ==> for user name ENTER:  anonymous
                             ==> password = your email address
  ENTER: bin
  
  ENTER: cd pub/dirdif/dirdif
  ---->  for MSDOS:  ENTER: get msdos/dirdif.zip   [appr. 3,600 kB]
  ---->  for unix:   ENTER: get unix/dirdif.zip    [appr. 2,200 KB]
  ENTER: quit


To unpack the zip-file:
-----------------------

  MSDOS: working directory is: C:\dirdif 
         Use WINDOWS option to "unpack" the dirdif.zip file into this
         directory 'dirdif' .  Note: do read file msdos.txt !
     
  Unix:  working directory is: $HOME/dirdif  
         Use "unzip dirdif" to store files into this directory 'dirdif'. 

  All unpacked files are stored in 'dirdif' and its subdirectories. 


Download DIRDIF for WINDOWS => WINGX 
------------------------------------

  Louis J. Farrugia has prepared a WINDOWS version for DIRDIF .
  A stand-alone version for WINGX/DIRDIF is available now at:
     http://www.chem.gla.ac.uk/~louis/software/dirdif/index.html 
 
     [ A link to this site is given in www.crystallography.nl ]

  The full updated WINGX system with DIRDIF-2008 will soon be released. 
  email:  louis@chem.gla.ac.uk

------------------------------------------------------------------------
Using an MSDOS-prompt window under MS-WINDOWS is simple: see msdos.txt .
------------------------------------------------------------------------
 
 
Note: the main difference between the MSDOS and unix versions are
      related to MSDOS Carr.Return-LineFeed and unix LineFeed only.  
      For MSDOS, the DIRDIF.EXE file is supplied;
      for unix ( and all other systems), the FORTRAN files are given.
