Ahh. I didn't understand this for a long time either--It's really
misnamed, IMHO. Basically, it's for looping. In the produced code, it
looks something like this:
doInitBody();
do {
// stuff within body
} while (doAfterBody == EVAL_BODY_TAG);
So, after each iteration, doAfterBody decides whether to go again. For a
simple loop, doInitBody might set a variable to 1 and then doAfterBody
would increment it and return SKIP_BODY when it reached a certain value.
I wish the docs would give and example like this--I had to read the
produced code to understand it.
