Hi all.
I just put online a first version of two tools that combine LaTeX and
python.
The first one, phystricks[1], is a python module intended to generate
pstricks code. The main features are
* you don't have to know pstricks (but you need to have some basics in
python)
* you have python instead

I've just double-checked. It returns a float in Python 2.x and an int in
