missing setfirstweekday in calendar module

[grakker]

I'm pretty new to python.  I wrote up a cgi script for a family
calendar.  It works great, but I would like to use the setfirstweekday
part of the calendar module, but it isn't there.  I'm running an
up-to-date sid debian install.  When I downloaded Python at work to
mess around during down times, I noticed that it does have a
setfirstweekday option.  Anyone know where I can find it?

Thanks
