Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

I would like to merge multiple PCB's into a single gerber file so I can get more than one PCB layout onto a board. Does any one know of a program other Gerbmerge that can do this? I'm trying to save my students some money getting their boards made. We've been using the toner transfer method but I'd like them to have the experience of sending a design out for fab. If I can do this then I can afford to pick up the tab for my students.

Thank you.
