To sawfish from metacity?

[Dale Huckeby <spock evansville net>]

Since I don't know of a sawfish for dummies list I hope this one isn't too 
inappropriate for my questions. I used sawfish before gnome dropped it (when 
it was still sawmill, I think) and liked it, but haven't been able to use it 
since. I recently decided to make another effort, but so far no joy. I've
been opening a terminal window and issuing the command:
: killall metacity; sleep 2; sawfish &
but it doesn't seem to change anything. If I close that terminal window I 
lose my panel as well as the close, maximize and minimize buttons on the 
windows of any apps I open. In fact, I lose the ability to do anything at 
all and end up having to do a Ctl-Alt-Backspace into a reboot, at which 
point I'm right back in metacity. I hope I'm not imposing but i wonder if 
anybody can give me some idea as to how to get rid of metacity (tenacity?) 
and replace it with sawfish in gnome as my window manager?

TIA,
