R help - Jan 2013 - Line breaks in documentation \useage

Hi again, R community.

I wonder how you do line breaks in \useage{} section in .Rd files. I  
am sure there's some tutorial for this somewhere, but I just haven't  
found it.

I have tried \\, \cr, \br and \newline, admittedly arbitrarily, but  
all of these produce warnings or errors.

br, Markku

The \usage{} section appears to be treated "verbatim" or as if it were
preformated.
So just put the line break "literally" in your *.Rd and it will 
automagically appear in the
resulting help.
