how to try OOo's 3.0 beta deb on Debian?

["H.S." <hs.samix@gmail.com>]

I am tempted to try the OOo 3.0 beta deb available here:
http://download.openoffice.org/3.0beta/

However, I want to keep it separate from the Debian's OOo installation
that I have so that I may purge the beta installation cleanly.

I am not very familiar with the internal workings of a deb file. Has
anybody tried the Beta deb above? Can it be removed cleanly after trying
it? Is there any way to make the deb installation on a specific
location, e.g. /usr/local?

Thanks.
