@emph{text} and @strong{text}
The @emph and @strong commands are for emphasis;
@strong is stronger.  In printed output, @emph produces
italics and @strong produces bold.
  
For example,
     @quotation
     @strong{Caution:} @samp{rm * .[^.]*} removes @emph{all}
     files in the directory.
     @end quotation
     
         *Caution*: `rm * .[^.]*' removes _all_
         files in the directory.
     
  The @strong command is seldom used except to mark what is, in
effect, a typographical element, such as the word `Caution' in the
preceding example.
  
In the Info output, @emph surrounds the text with underscores
(_), and @strong puts asterisks around the text.
  
Caution: Do not use@strongwith the wordNote; Info will mistake the combination for a cross reference. Use a phrase such as Please note or Caution instead.
