I just noticed on the page
http://python.sourceforge.net/devel-docs/ref/summary.html
that the shifting operators are not shown as << and >>, but
as the double-angle-quote characters ("guillemets"?) that the
French are fond of. This should probably get fixed, though
i'm not enough of a TeX expert to know how (will a couple of
backslashes do the trick?).
