puush-linux gnome-screenshot -f does not exist

I am running GNOME 3.4.2, and in this version the -f command to set the filename does not actually exist in the program.

keiko@KFKLDeb:~$ gnome-screenshot -f "Test" ** (gnome-screenshot:32348): CRITICAL **: Unable to parse arguments: Unknown option -f

I don't have a system available atm for gnome-screenshot. Could you do me a favour and copy and paste the help dialog from the command line for gnome-screenshot? I.E. gnome-screenshot -h
