of code. It respects whitespace and newlines, and will not normally attempt
to wrap your code. However, if your individual lines are too long, this can
overflow the width of the column and even run off the page. Three optional
attributes - maximumLineLength, splitCharacters and newLineCharacter -
can be used to do simple wrapping. maximumLineLength will force the text to
wrap. Note that this simply counts characters - it takes no account of
actual width on the page. The examples below wrap lines above a certain length
and add a '>' to the start of the following line.
