This is not a real multcolumn text because in verbatim text each space
in the input appear also in the output and in the examples spaces
where used to align the code comments on the same position.

You can use the narrower environment to change the margins for a certain
text area and use the paragraphs environment to create two columns
with different widths in this area.
