And the -psvn... option is under the hood passed to your programs when 
you run them from Finder on Mac OS X, see 
http://forums.macrumors.com/showthread.php?t=207344 and 
http://stackoverflow.com/questions/10242115/os-x-strange-psn-command-line-parameter-when-launched-from-finder 
. When programming Mac OS X GUI programs that interpret command-line, 
you have to be ready to detect (and usually ignore) the -psvn... options.
