+This LaTeX package allows to compute the mass of a printed version of a
+document, useful e.g. to determine the postage when sending it by snail mail.
 
 Warning/Disclaimer: The mass of (printer's) ink has to be added and that
 of envelope, address sticker, stamps,... Thus this is only an estimation
 without guarantee - do not sue me, if you have got to pay excess postage!
