CSS3 prefixer generator

Hi: I'm looking for an original PHP based CSS3 prefixer tool. Basically it will be a form box where users can enter arbitrary pieces of CSS, and the tool will scan it for all known standard CSS3 properties and add above them the vendor specific versions of the properties. * It should not alter the CSS code in any other way otherwise. * It should allow the admin (me) to add or remove from the script the list of CSS3 properties it scans for (in the event when new CSS3 properties are introduced. * It should have a "reverse" option, where CSS code with vendor specific CSS properties are removed and replaced only with the official CSS3 versions (if they don't already exist in the code) instead. In general, create a robust CSS3 prefixer tool that takes into account potential malicious input, overly large inputs etc.
