[mkgmap-dev] [Patch v2] set program return code and improve logging

Hi all, attached is version 2 of the patch. Changes to v1: - change Main.main to Main.mainStart() which returns an int - let Main.main call mainStart() and use System.exit(1) in case of errors - let unit tests call Main.mainNoSystemExit() which doesn't call System.exit(). - synchronized -> volatile for access of field programRC For version 1 see http://gis.19327.n5.nabble.com/Patch-v1-set-program-return-code-and-improve-... If I hear no complains I'll commit it on friday. Gerd
