There's a bit of info in third party tools, A few good contributes
in contributes. AUG has some good info as George has some good stuff
in the last 5 issues I think.

But it also depends wether you want to stick with c-script in A7 or
be converted and go with A7's lite-c format...

As far as new syntax, There's info in the manual about what has changed to what. So start off in those few places first hopefully that'll get you going..
