Sub Articulo 63.1

I just had a look, and it takes an option for the driver:
\usepackage[dvips]{dropping}
You can declare 
\usepackage[other]{dropping}
to do things differently, but the dvips option apparently
has nothing to do with dvips!  Only for the availability of
scalable fonts or a maketexpk script.  So you may as well
say [dvips] even though you don't use it.
