1) Untar everything into its own directory, preferably under the
   webseller-directory, put it there for example in a directory called
   /wsadmin.
2) Take appropiate steps for protecting that directory from unwanted 
   visitors (e.g. put some kind of .htaccess in it).
3) Edit wsadminconfig.php to suit your needs. At least $inifile and
   $imgdir has to be set correctly.
4) $imgdir must be writeable for the web-server to make picture-uploads
   work. chgrp that directory to the group your webserver is running at
   and make that dir group-writeable.
   (e.g. chgrp nobody <$imgdir> && chmod g+x <$imgdir>)
6) Start your browser and open http://<your-webseller-url>/wsadmin/admin.php,
   authenticate yourself and go on.

Under normal circumstances the script uses its own stylesheet 
(wsadminsheet.css). It is possible to make the script use the stylesheet
also used by the WebSeller. Therefore you have to uncomment the corresponding
line near the beginning of admin.php. But this will lead to some inevitable
changes in the code of admin.php or the stylesheet.
