[xmonad] Possible to change location of xmonad.hs?

[Joseph Garvin]

I like to put all of my important configuration files inside ~/etc for
easy backup. Is there a way to have xmonad load ~/etc/xmonad.hs in
place of ~/.xmonad/xmonad.hs? I know I could use a symlink but then
I'd have to remember to set that up again, would prefer if there was a
command line option to xmonad or someway to specify in
~/.xmonad/xmonad.hs that it should just look at ~/etc/xmonad.hs.
