XtalViewDarwinv1.0.tar.Z contains executables for XtalView for
use on Mac OS X 10.1 and above.  

Prerequisites
1. Working X Windows system such as XDarwin. This is available at the 
Apple OS X software site: http://www.apple.com/macosx/x11/
(Note if you have an older X windows such as XDarwin, try the new one
from Apple which is much faster!)
2. Base system for XtalView.  If you do not have an existing XtalView
installation you can obtain this from CCMS.  For downloading instructions
send an email to CCMS mail server ccms-request@sdsc.edu. Leave the subject
blank and put the single line 'get xtalview' in the message body.  A return
email will contain full instructions. If you do not want to install
another architecture, but only the Mac version, you only need xtalview.tar.Z.
3. 3-button USB mouse.  These cost about $15 and the program will be difficult
to use without one.  (Note almost all PC wheel mice use the wheel as the middle
button). Use can use a single button mouse or laptop trackpad by holding the
ctrl and apple keys down, but I find this very awkward.

Installation
Place the tar file in your $XTALVIEWHOME directory.  Type:
tar -xvZf XtalViewDarwinv1.0.tar.Z

This will place the executables in bin/powerpcDarwin5 and make a symbolic link 
to bin/powerpcDarwin6.  It also replaces bin/share/archosv.  (If you have 
modified this file, you should back it up first.)

Verify installation

cd XtalView
source XtalView.env and then type "which xfit".

You are ready to go.

This is a beta version kindly supplied by George Philips.  There are
a number of known issues, but the package works well.  CCMS will be
working to get an official distribution ready at their web site with
a newer version of XtalView.
