Here are the rules for building input ranges:
\begin{itemize}
\item A number represents a page number
\item A page label may be used in place of a number e.g \texttt{[iii]} represents the first page found which is labelled \texttt{iii}.
\item A tilde (\texttt{\~{}}) defines a page number counting from the end of the document rather than the beginning. Page \texttt{\~{}1} is the last page, \texttt{\~{}2} the penultimate page etc.
\item A dash (\texttt{-}) defines ranges, e.g. \texttt{1-5} or \texttt{6-3}.
\item A comma (\texttt{,}) allows one to specify several ranges, e.g. \texttt{1-2,4-5}.
\item The word \texttt{end} represents the last page number.
\item The word \texttt{end} represents the last page.
\item The words \texttt{odd} and \texttt{even} can be used in place of or at the end of a page range to restrict to just the odd or even pages.
\item The words \texttt{portrait} and \texttt{landscape} can be used in place of or at the end of a page range to restrict to just those pages which are portrait or landscape. Note that the meaning of ``portrait'' and ``landscape'' does not take account of any viewing rotation in place (use \texttt{-upright} from chapter 3 first, if required). A page with equal width and height is considered neither portrait nor landscape.
\item The word \texttt{reverse} is the same as \texttt{end-1}.
\item The word \texttt{all} is the same as \texttt{1-end}.
\item A range must contain no spaces.
\item A tilde (\texttt{\~{}}) defines a page number counting from the end of the document rather than the beginning. Page \texttt{\~{}1} is the last page, \texttt{\~{}2} the penultimate page etc.
\item Prepending \texttt{NOT} to a whole page range inverts it.
\item Prepending \verb!<n>!\texttt{DUP} to a whole page range duplicates each page of the range \verb!<n>! times.\index{page!duplicate}
