But what I don't like is the following:
If you have an alias to the cool game you just wrote and compiled,
delete the application, recompile it, and then do a Get Info on
the alias, this will show the correct path and name that you want
(e.g. HD40SC:Cool:.Non-Debug Files:HejSvejs), but pressing Find Original
gives you the prompt "Can't find file"(or something like that).

OK, OK, its only my opinion...
