I am a long time C programmer, but I've always thought that
java is a rather good C-like language. Much better than C++

As well as being placed into the .img, all copyright messages are
collected, de-duplicated and placed into the .tdb file. You can
display all those copyright information in mapsource via
help->about->product info.

The tdb file is not in the gmapsupp.img file though, so the boot up
message can only come from one of the .img files, probably the first?
Not certain what exactly it uses.

Really the .osm and .pbf files should contain the copyright information,
(like .mp file do), and I do hope this happens before the switch to the 

So I'd like to apply your patch but change the option wording to
'specify a copyright message for files that do not contain one'
or something like that.
