Perhaps we have different definitions of "easily" ;)

I like this approach, primarily as it keeps all the mods in my .ly files, 
instead of tweaking sources...

Being a scheme newbie, I tried a quick hack job on the "weight-
flag/inverted-flag" example.  It works on TabStaffs, but I have a few 
questions about the implementation:

1) Is the \autoBeamOff required?  Is there a way to allow autobeaming and 
still override the flag style?

2) How does one locate the end of the stem for connecting a line to it?  For
that matter, how does indicate a line should be drawn in scheme?

3) Is there any (better) documentation of overriding default stems/flags?
