Greetings,

I am looking for a LaTeX macro package for drawing trees.  Those
trees are to represent extensive form games and I need the following
capabilities:

 1. Each node may have *any* number of child nodes (2,3,4...).
 2. I would like to put an arbitrary label on a node.
 3. Ditto for any edge connecting two nodes.
 3. Preferably, I would also like to join some of the nodes "at the
    same level", i.e., having the same parent, with a line, broken or
    otherwise  (this is a representation of "information sets" in
    Game Theory lingo).
 4. I really don't care if the tree expands from left to right, or
    top-down, or bottom-up.  Anything will do.

I went through the excellent tex-index (by David Jones) and found a
few packages which meet some, but not all, of the above requirements.
Does any body know of a package that can do the things I want to?

On a similar note: all the packages that I saw use some "higher level"
constructs like, e.g., \branch, \node, etc., which are expanded by
the macro package.  Is there a "macro expansion" package that that
can expand all these commands to LaTeX picture drawing primitives
and save to a file?  That way, I could use TeXcad to touch up the
pictures visually for any small changes that are not possible from
within the macro package itself.  I thought it would be a neat idea
anyway ...

Any help will be greatly appreciated.  Thanks in advance.

Sincerely,
