Hi Ajay.

1. I have attached an example of how to use constraints in LBJ. This is a
simplified version of the Illinois Semantic Role Labeler. There are two
classifiers called the VerbArgumentIdentifier and the
VerbArgumentClassifier. The three constraints in the attached file only
involve the second one. Please take a look and see if it helps.

2. Regarding an IDE, the LBJ download package comes with a vim mode for
syntax highlighting LBJ. I personally use Emacs' java mode and it is
almost good enough.

I think the examples in the tutorials work. I haven't tried them in a
while, though. Could you point me to the differences between the LREC
paper and the examples in the tutorials?

3. There isn't an implementation for CoDL within LBJ. You might have to
write one.
