Translating english into amglish

Hi All, I'm based in Australia but my blog is predominantly read by Americans. I'm wondering if anyone knows of a class that will translate Australian / UK / Canadian / Whathaveyou English spellings into their American English equivalents? In other words, a class that will take a string with spellings such as "The colour of my neighbour's car, I recently realised, isn't grey after all" and will return "The color of my neighbor's car, I recently realized, isn't gray after all", and so on. Given time I'm sure I could work out many of the transformation rules myself, and implement them via regular expressions, but why reinvent the wheel if someone has already done so?
