Hi,
I need to draw trees with nodes that are 6-sided polygons. pstree gives
only up to 4-sides: "\Tdia". Is there a way to go beyond diamond nodes?
Thanks,
- WK

you need a closed path to fill something. "(! " starts a postscript
command sequence. It is nearly the same like the code from
the HP pocket calculators. The first solution with the polar coordinates
is a bit tricky. It does not has a closed path, so you are not able to
start a fill command.
