===Usage:===
 
Use one section between '''<tt><nowiki><rss></nowiki></tt>'''-tags for each feed. The rss section may contain parameters
 
separated by a pipe'''<tt><nowiki> ("|")</nowiki></tt>''', just like links and templates. These parameters are supported:
 
 
{|
 
|-
 
|| '''<tt>charset = ...</tt>'''            ||The charset used by the feed. iconv is used to convert this.
 
|-
 
|| '''<tt>short</tt>'''                  ||Do not show the description text for each news item.
 
|-
 
|| '''<tt>max = x</tt>'''                  ||Shows x most recent headlines.
 
|-
 
|| '''<tt>highlight = term1 term2  </tt>'''  ||The terms separated by a space are highlighted.
 
|-
 
|| '''<tt>filter = term1 term2  </tt>'''    ||Show only rss items containing at least one of the terms.
 
|-
 
|| '''<tt>reverse</tt>'''                ||display the rss items in reverse order.
 
|-
