Why does kdebase depend on xdm? Right way to disable xdm?

[Daniel Barclay <daniel@dsb.smart.net>]

Can anyone tell me why the kdebase package depends on xdm?  


Also, what's the "right" way to display xdm without removing
the package?


(I want to try out KDE, but don't want to use xdm.)


Thanks,


Daniel
