Where is basedebs.tgz?

[Simon Eilting <s-eilting@gmx.de>]

I'm trying to install woody from the net. The documentation says I need 
a file called 'base2_2.tgz' (this is for potato, right?), and the 
installer says I need a file called 'basedebs.tgz'. The base2_2.tgz 
doesn't seem to work and there's no 'basedebs.tgz' on the mirrors. Do I 
have to install the base system directly from the net (I can't)?
