[mkgmap-dev] Wondering about mkgmap usage.

Hi, I'm using mkgmap since a while and it works great. Good work and thanks to all of the developer. I know how many time you are investing into it and how many time such a OS project needs to care about. So my question is. I already have seen that some of the map compilers are calling the mkgmap with the typ file at the end. For example: java .. -jar mkgmap.jar [option] typfile.typ I also tried it and I found no advantage or difference to a call without the typ file? What is the reason for this? I also didn't find any doc for this. Thanks, Marco
