Summary description: Provides the command \hrefdisplayonly .
License type: lppl

Announcement text: 
----------------------------------------------------------------------
This package provides the command \hrefdisplayonly (instead
of \href). While the (hyperlinked) text appears like an
ordinary \href in the compiled pdf-file, the same text will
be "hidden" when printing the text. It is not really
invisible, but just has the same colour as the background
(default: white). Therefore the layout is not changed when
printing the document.
