% This macro allows one to search throgh the bodies of the articles in the
% current newsgroup.  It binds the function 'search_newsgroup' to the '$' key
% in article mode.

% If you need more sophisticated features, you can use the ``improved search''
% available from <http://slrn.sourceforge.net/macros/>
