Metronome marks

[Atte André Jensen]

Hi

I've looked at the (to me) new \tempo, and I don't know how to make it 
do what I need. I'd like to have "Andante (H = +- 48)" printed above the 
meter, where:

* H is a halfnote

* +- is a + printed above a -

* I'd prefer to attach it to a voice with only spacers, but that seems 
to print it more than a bar too much to the right

* I'd like to be able control the vertical and horizontal placement of 
the mark

If someone could help me out or point me to a place in the docu I'd be 
most happy. Thanks in advance.
