htmlpurifier/library/HTMLPurifier/ChildDef/StrictBlockquote.php
Edward Z. Yang 522c8ed7c2 [3.1.0] The bulk of autoload support added
- Add FSTools:globr()
- require_once removed from all files
- HTMLPurifier.autoload.php added to register autoload handler
- Removed redundant chdir in maintenance script
- Modified standalone to use HTMLPurifier.includes.php for including stuff
- Added maintenance script remove-require-once.php which we used once and should never use again
