SVGViz-Installation
++++++++++++++++++++++++++++++++++

PLACEMENT

1) download SVGViz zip, unpack and put the SVGViz package into the
   directory "extensions". Do not change the name of the directories
   or files.

2) put the follwing lines into the file "LocalSettings.php" (just after
   "require_once ("includes/DefaultSettings.php")" or at the end of
   the script)

# SvgViz Extension
require_once("extensions/SvgViz/SvgViz.php");

3) Set the permissions of the "tempfiles" directory to "world-write", so
   that Php can create temporary files in this directory. Alternatively,
   and better, chown this directory to the owner of the httpd processes.


DEFINE PATH AND GLOBALS

4) Open the file "define.php" in the directory "includes" of SVGViz
   (go to "SVGViz" directory and find "includes" directory there).

5) Define your default selected Node name: open the script
   "define.php" in the directory "includes" - define the global
   variable "$initialNodeName" with your default Node-name.

VIEW

6) Go to specialpages on MediaWiki. You will find "SVGViz" in the
   list. You should also have link called "Visualise this article" in
   your left menu.

IF SOMETHING GOES WRONG (added by DKS / June 26)

There may be a problem with wikiproject.php, i.e. definition of file
and URL pathes (look at the beginning and the end of the file).

At TECFA we have the following setup (file LocalSettings.php):

$wgScriptPath	    = "/mediawiki";
$wgScript           = "$wgScriptPath/index.php";
$wgRedirectScript   = "$wgScriptPath/redirect.php";

# DKS 3/2006
$wgArticlePath      = "/en/$1";

$wgStylePath        = "$wgScriptPath/skins";
$wgStyleDirectory   = "$IP/skins";
$wgLogo             = "$wgStylePath/monobook/tecfa/wiki.png";

$wgUploadPath       = "$wgScriptPath/images";
$wgUploadDirectory  = "$IP/images";

Apache httpd.conf looks like this:

Alias /mediawiki "/data/portails/mediawiki"
Alias /en "/data/portails/mediawiki/index.php"
Alias /en/index.php "/data/portails/mediawiki/index.php"
