Formatting F# code on Blogger

There doesn't appear to be too many tools on the internet for nicely formatting F# code on Blogger. I recently stumbed across CodeHTMLer which produces output like this:

  1 let rec interpret =
  2     function
  3         | DigitExpression a -> a
  4         | ParenthesizedExpression (l, o, r) ->
  5             let left = interpret l
  6             let right = interpret r
  7             match o with
  8                 | Add -> left + right
  9                 | Multiply -> left * right

See my last post for an example in C#
