I keep many dump files around with different names, to easily suspend, switch, and resume acme configurations depending on what I need to work on. This significantly reduces my context switch time, over and above the advantage I get from guide files keeping me from (mis)retyping commands.
in acme: highlight and execute "Dump /home/me/dump/whatever" in shell: rum "acme -l /home/me/dump/whatever" Jason Catena
