Help for installation on Debian

[Hervé Piedvache]

Hi,

I would like to install Kolab 2 on Debian SID ...

But I'm a little anxious with the installation system ... I have downloaded 
all the .rpm packages from :
<http://www.erfrakon.de/projects/kolab/download/kolab-server-2.0/testing/current/SRC/>

There is no documentation or anything to help ... I suppose that I have to do 
to start the installation process :

./obmtool kolab

BUT, I would like to know first what will append with my classical Debian, 
and/or personnal installation ... for example Bison, bzip2, clamav etc. from 
Debian, or my personnal installation from Apache ... 
Does this installation system will erase my debian package ???
What will happend exactly with those RPMs?

Why there is no .deb files for Kolab installation on Debian ... ?

Any help will be welcome ! ;o)

Regards,
