Javascript.php library broken

[eluser]Unknown[/eluser]
After hours of fiddling with the javascript library and trying to follow the multitude of examples on the web, I finally looked into the source and must say that it makes no sense

The standard external method always generates a bogus script URL because it simply duplicates the argument passed in. By setting $this->_javascript_location to the $external_file argument and then returning $this->_javascript_location.$external_file one always ends up with something like http://localhost/js/jquery.jsjquery.js for example

Or am I completely misunderstanding this? Can someone explain how this is supposed to work? All I want to do is to add additional javascript libraries I have in a special directory I have specified in config

<code>
function external($external_file = '', $relative = FALSE)
{
if ($external_file !== '')
{
$this->_javascript_location = $external_file;
}
else
{
if ($this->CI->config->item('javascript_location') != '')
{
$this->_javascript_location = $this->CI->config->item('javascript_location');
}
}

if ($relative === TRUE OR strncmp($external_file, 'http://', 7) == 0 OR strncmp($external_file, 'https://', 8) == 0)
{
$str = $this->_open_script($external_file);
}
elseif (strpos($this->_javascript_location, 'http://') !== FALSE)
{
$str = $this->_open_script($this->_javascript_location.$external_file);
}
else
{
$str = $this->_open_script($this->CI->config->slash_item('base_url').$this->_javascript_location.$external_file);
}

$str .= $this->_close_script();
return $str;
}
