Re: Continue Eclipse Freemarker DLTK?

I agree with your suggestion.

My first step is to swith to 2.3. I think the Outline is not really
important for the moment and AST is not important for the moment.
If you are OK, I would like to manage with 2.3 the 2 features (which
already works with 3.0) :

 * syntax errors
 * dbgp debugger

Are you OK with that?
