@cartouche: Rounded Rectangles Around ExamplesIn a printed manual, the @cartouche command draws a box with
rounded corners around its contents.  You can use this command to
further highlight an example or quotation.  For instance, you could
write a manual in which one type of example is surrounded by a cartouche
for emphasis.
  
@cartouche affects only the printed manual; it has no effect in
other output files.
  
For example,
     @example
     @cartouche
     % pwd
     /usr/local/share/emacs
     @end cartouche
     @end example
     
surrounds the two-line example with a box with rounded corners, in the printed manual.
