     HTML Purifier attempts to be as smart as possible when registering an
     autoloader, but there are some cases where you will need to change
     your own code to accomodate HTML Purifier. These are those cases:
-    
+
     PHP VERSION IS LESS THAN 5.1.2, AND YOU'VE DEFINED __autoload
         Because spl_autoload_register() doesn't exist in early versions
         of PHP 5, HTML Purifier has no way of adding itself to the autoload
         stack. Modify your __autoload function to test
         HTMLPurifier_Bootstrap::autoload($class)
-        
+
         For example, suppose your autoload function looks like this:
-        
+
             function __autoload($class) {
                 require str_replace('_', '/', $class) . '.php';
                 return true;
             }

         A modified version with HTML Purifier would look like this:
-        
+
             function __autoload($class) {
                 if (HTMLPurifier_Bootstrap::autoload($class)) return true;

                 return true;
             }
-        
+
         Note that there *is* some custom behavior in our autoloader; the
         original autoloader in our example would work for 99% of the time,
         but would fail when including language files.

         HTML Purifier will register the function for you. But if it is

     Users should also be on guard if they use a version of PHP previous

     can use it like this:

     This is equivalent to including HTMLPurifier.includes.php, except that
     the contents of standalone/ will be added to your path. To override this
     behavior, specify a new HTMLPURIFIER_PREFIX where standalone files can
     be found (usually, this will be one directory up, the "true" library
     directory in full distributions). Don't forget to set your path too!

     The autoloader can be added to the end to ensure the classes are
