 Simplify the RDF::Writer method if you have already an rdf graph like:
 
+```ruby
     @rdf = RDF::Graph.new
     RDF::Reader.for(format).new(rdf) do |reader|
       reader.each_statement{ |statement| @rdf << statement }
     end
+```
 
 To parse it to another format simply use:
 
+```ruby
     RDF::Writer.for(format).buffer(:encoding => Encoding::ASCII) do |writer|
       writer << @rdf
     end
+```
 
 instead of:
 
+```ruby
     RDF::Writer.for(format).buffer(:encoding => Encoding::ASCII) do |writer|
       @rdf.each{|statement| writer << statement}
     end
+```
