57 Since version 6, you may also use
58 \begin{verbatim}
59 \cofeBleed{alpha}{scale}{angle}{xoff}{yoff}{bleed}{variety}
60 \end{verbatim}
61 to place a \texttt{variety} $\in [0,4]$ with random parameters on the current
62 page. There is now also a package option to put a bleeding coffee throughout the pages like
63 \begin{verbatim}
64 \usepackage[bleed]{coffee}
