 /**
  * HTML Purifier Phorum Mod. Filter your HTML the Standards-Compliant Way!
- * 
+ *
  * This Phorum mod enables users to post raw HTML into Phorum.  But never
  * fear: with the help of HTML Purifier, this HTML will be beat into
  * de-XSSed and standards-compliant form, safe for general consumption.
  * It is not recommended, but possible to run this mod in parallel
  * with other formatters (in short, please DISABLE the BBcode mod).
- * 
+ *
  * For help migrating from your previous markup language to pure HTML
  * please check the migrate.bbcode.php file.
- * 
+ *
  * If you'd like to use this with a WYSIWYG editor, make sure that
  * editor sets $PHORUM['mod_htmlpurifier']['wysiwyg'] to true. Otherwise,
  * administrators who need to edit other people's comments may be at
  * risk for some nasty attacks.
- * 
+ *
  * Tested with Phorum 5.2.6.
