The '--' string tells the argument parser (getopt(3)) that there are no more 
flag arguments and that everything else is literally an argument.  This 
convention is enforced by getopt(3).  Argument parsers written before the 
existence of getopt(3) may or may not support this convention.

For filenames, it is really best to always use the ./ prefix, or whatever other 
directory make sense.  This will always work, regardless of a programs command 
line handling.
