[Yaml-core] Neil's C

Let's see if I can ask some intelligent-sounding questions:

The 2 that come off the top are:

What's push/pull-style parsing?
and (the same?)
What's SAX-style?

(Presumably, if I got the above, I wouldn't have to ask:
When is 'leaf-handler' called?  After the leaf is parsed, right?
since it's got the leaf-value in its arg-list.  But, then what
does it have to do?  The only available job is to call the
semantic routine, which I gather is passed to it in the void *.

Doesn't seem like much of a job.)
 
Similarly, what does 'series-push' do?

Minor jargon:  What's YAC and YACC?

Gentlemen, care to enlighten me?
