How do I install gnus cvs?

[Rodolfo Medina]

Hi, everybody.

I followed the steps described at

http://www.gnus.org/distribution.html

and downloaded the cvs gnus directory.
But there is no README nor INSTALL file.
How shall I install cvs gnus on my system?
With the usual './configure', 'make' and 'make install' trilogy?
And how shall I tell emacs to use the freshly installed cvs gnus
instead of the one already present in my emacs installation?

Thanks in advance for any reply,
Rodolfo
