[Haskell-cafe] Alex question

I want to make Alex to parse a file using states. I wrote a simple
basic wrapped .x file but it complaints that it doesn't know the
"begin" symbol. As listed here[1], my code does something like this:

<0> \/{2} { begin italic }

Am I doing something wrong? Should I manage myself the states? Should
I use another parser generator?
