I read on the blog that there is formatter that we can use and I quote this :
"We'd also like to encourage people to write their own formatters. There is a framework on the server-side for writing formatters, and it is actually quite easy. The Zip formatter, for example, is less then two pages of code."
I'd like to write my own formatter so can someone explain how I can do that?
What is this framework? where is it?
