SyntaxHighlighter 2.0 Haskell Brush

I know there are a lot of Syntax Highlighter out there, but I love Alex Gorbatchev SyntaxHighlighter 2.0.

I had to write a new brush for Haskell language since I start searching for one without any success, this is my first attempt to make a SyntaxHighlighter Brush (and I just starting learning haskell a few weeks ago).

module sample where
{-
Multiline comments
this is a comment too
-}
isDigit :: Int -> Int
abs | n >= 0 = n
    | otherwise = -n
-- Single line comments allowed
