</div>

when we do

ri Kernel#printf

it shows some basic info,  
but if we do

ri Kernel#sprintf

a lot more is shown for the details.

I wonder how a suggestion can be added so that printf includes a note to  
see sprintf?

You can edit the rdoc associated with printf to add such a note, then  
submit a patch to [redmine.ruby-lang.org](http://redmine.ruby-lang.org)
