Installing 2.0 with a 1.5.* version in place

[Thaddeus L. Olczyk]

Several questions about installing 2.0b2.
First when will 2.0final be ready?
If someone says this week, then I am not going to bother
until final is out (why do it twice in a short span?)

Second do I have to unistall 1.5.*, or can I just install 2.0
over it?

Third what other "software packages" am I going to have to
update ( WinPython, IDLE, libraries...).

I'm doing this both on linux and on Win NT 4.0sp1000000 ( or whatever
the latest).
