Oh, thanks a lot. I was so stupid that I somehow overlooked that it was
a chapter about inclusion of figures in other graphics and not in text,
although I've seen these pages quite a couple of times.

I want to make something like

[start of TeX code]
    \displaystyle{\underbrace{x^2+y^2=z^2}_{\hbox{simple equation}}}
[end of tex code]

except that there has to be a metapost picture instead of "x^2+y^2=z^2"

Or, see page 22 of http://remote.science.uva.nl/~heck/Courses/mptut.pdf.
(The example is made by stretching normal braces, but that's ugly)

Is it possible to place a graphic inside a \hbox in some btex ... etex
or textext expression? In that case this would help me a lot, otherwise
I'll keep playing with \[something]MP[something].

Thanks again,
