Minimize All aka Show Desktop with exceptions via wmctrl

#!/bin/bash
#This script should minimize everything except conky and  aterm
#Add/remove entries according to example
#I use this script as alternative to openbox's wincmd which minimizes conky and aterm
#This script uses toggle by default, you could also use "add" to only minimize windows not show back
#Do to do this just change "toggle" to "add"
#Script addapted from  http://crunchbang.org/forums/viewtopic.php?id=12917
