I just opened the pdf manual located at:
and the code examples on pages 6 and 29 go off the page so you cannot read the text at the end of the line.
Additionally, on pages 3, 7, 12, 14, 15, 17, 19, 20, 24, 25, 26, 33, 36, 42, 45, 46, 48, 51, 62, and 65 the text is outside the margins.
It appears that this happens mostly whenever there are code examples. If you are using the 'verbatim' package, then you will need to either adjust the indentation for the code or add some line breaks to the code examples so that they don't go outside the margins or off the page.
