Hi Kib2

I'm CCing back to the list - hope this is OK.

It isn't a method - it is just a variable. You are right that it
doesn't seem to be  mentioned in the docs. I don't know if this was
just an oversight, or if it is because it is not supposed to be part
of the public API. Could the developers comment on this?

The way I found out about it was using the "?" feature in IPython,
which is an interactive python interpreter.

As far as I know, there is nothing built in to PyX for doing this. It
would be great if there were!

If you want to implement this yourself, then the wikipedia article
looks like a reasonable general introduction
(http://en.wikipedia.org/wiki/B%C3%A9zier_curve). The way metapost
does it seems to be reasonably well documented - see
http://www.tlhiv.org/MetaPost/documentation/, particularly
Metapost_Curves.pdf
