I am about to run sudo apt-get install dwm on ubuntu 12.04.
When I was on arch linux dwm was installed to a folder and recompiled in the folder when you made changes to it. (Edit settings). I am sure you understand how important it is to be able to recompile the files as its the only way to make changes to dwm as far as I know.
Where exactly is the folder with the files installed to? Figure I should find this out before installing DWM blindly!
