kde4 without losing kde3?

[Kent West <westk@acu.edu>]

I've found the installation instructions for installing KDE4 on my Sid
box (http://pkg-kde.alioth.debian.org/experimental.html), but I'm
unclear if this supersedes my working KDE3 setup or not.

Can I use these instructions to install 4, and if 4 causes me to much
grief, be able to switch back to 3?

Or, if 4 doesn't work for me, can I purge the 4 packages, remove the
experimental stuff from my sources.list file, and reinstall 3 and be
back to normal? (Will I have to move my ~/.kde? directory? (I'll make a
backup of my version 3 .kde stuff first, just in case.))

Thanks!
