Sure, ok, forget the .desktop scenario, the real useful scenario is the same 
than -caption and is actually starting something from a command line and 
giving it a custom icon, like let's say, konsole or kdialog but you pretend 
they are something you created for your own command line program.

Does that make more sense?
