I played around with having config.php detect the basedir and rooturl 
if it is not given in config.ini.  This only left the db variables and 
dir.include.  I also played around with setting up variables for the 
domain name and host name.

Worked OK except for the scripts in the admin directory.  The rooturl 
changed and screwed it all up.  The rooturl has /admin appended.  Then 
adminurl appends /admin again.  Anybody got any good ideas?  I sure 
don't.

// basedir -> complete filesystem path to the pages
if(empty($_PSL['basedir'])) {
   $_PSL['basedir'] = getcwd(); 
}

...skip...

// rooturl -> The base URL for the PHPSlash site.
if(empty($_PSL['rooturl'])) {
   $url = parse_url($_SERVER['REQUEST_URI']);
   $pathinfo = pathinfo($url['path']);
   $_PSL['rooturl'] = $pathinfo['dirname'];
}

// root.http_host -> The hostname of the PHPSlash site.
if(empty($_PSL['root.http_host'])) {
   $_PSL['root.http_host'] = $_SERVER['HTTP_HOST'];
}

// root.domain -> The domain for the PHPSlash site.
if(empty($_PSL['root.domain'])) {
  $server_parts = explode('.', $_PSL['root.http_host']);
  $count = count($server_parts);
  if($count > 1) {
     $_PSL['root.domain.tld'] = $server_parts[$count-1];
     $_PSL['root.domain.name'] = $server_parts[$count-2];
     $_PSL['root.domain'] =  $_PSL['root.domain.name'] .".". 
$_PSL['root.domain.tld'];
      unset($server_parts[$count-1]);
      unset($server_parts[$count-2]);
      $_PSL['root.domain.host'] = implode('.', $server_parts);
  } else {
     // no tld - like localhost
     $_PSL['root.domain.tld'] = '';
     $_PSL['root.domain.name'] = $_PSL['root.http_host'];
     $_PSL['root.domain'] = $_PSL['root.http_host'];
     $_PSL['root.domain.host'] = '';
  }
}
