wmaker

[Paul Fischer <paul.fischer@carambole.com>]

hi all,
I'm a Debian newbie running potato 2.2.r3
now my question is,
I'have xdm and severar Window Managers installed, 
how can I make Wmaker the "default" Window Manager
at startup, now it is icewm, 
I want to keep my other Window Managers as well
and an easy way switching from Wmaker to any other
of my Window Managers....
btw. what files are involved, e.g. .xinitrc 
how should the file look like ?

tanks in advance 
Paul
