The Idea was to bypass the lame gui using the cmdline opts but it can't combine on export.
So the second try was just translating then doing the 1hour-clicky-dance to combine everyhing.
But as it turns out it's also unable to rotate on cmdline. (gerbv version 2.6.0)
Avoid gerbv for panelizong. it is utterly hosed software. Here's my notes:
