In 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.
The @cartouche command affects only the printed manual; it has
no effect in the Info file.
For example,
@example @cartouche % pwd /usr/local/lib/emacs/info @end cartouche @end example
surrounds the two-line example with a box with rounded corners, in the printed manual.
In a printed manual, the example looks like this:
% pwd /usr/local/lib/emacs/info
