As far as I know, stars are the only way to render a list inOn Sat, Mar 20, 2010 at 2:00 PM, Charles R Harris

restructured txt, otherwise it looses the list formatting. I tried

several versions, but never found a different way. (I don't remember

whether the empty lines are strictly necessary in sphinx docs, but

they are in rst.)

But they can't be read on a terminal. The Numpy docstring format was
designed to save vertical space, all those stars and blank lines undoes
that effort.

But, the markup creates nice hml and htmlhelp docs, and it can be

published as pdf.

If we need that, let's fix the numpy format so we can get rid of the stars. Personally, I think the html docs should be secondary, i.e., as long as we are stuck with terminals, screen readability comes first.
