%%%
%%% This document class is based on the "scrartcl" class
%%% from the KOMA script bundle.
%%% Following additional packages are required:
%%% amsmath, babel, endfloat, endnotes, geometry
%%% ifthen, lmodern, natbib, setspace, stringstrings, textcomp, url
%%%
%%% The class provides the following options:
%%% noendfloat    - don't move floats to the end of the paper
%%% noendnotes    - don't use endnotes (use footnotes)
%%% titlepage     - create "first" title page with title, authors' names,
%%%                    affiliations, and address of corresponding author
%%% nosecondtitle - do not create "second" title page with (repeated) title
%%%
%%% This class selects the BibTeX style "elsart-harv.bst".
%%% (see http://www.elsevier.com/wps/find/authorsview.authors/elsart)
%%%
%%% This class provides 4 new commands:
%%% \affiliation     specify affiliation(s) of the authors
%%% \cauthormark     mark the corresponding author (by an asterisk)
%%% \cauthoraddress  specify address of the corresponding author
%%% \keywords        specify some keywords (separated by semicolons)
%%%
%%% The Journal of Rural Studies requires that you use single quotes
%%% you could do this with the ``csquotes'' package:
%%% \usepackage{csquotes}
%%% \MakeInnerQuote{<yourQuoteCharacter>}
%%%
%%% The manuscript submitted to JRurStud shouldn't include any figures.
%%% If your paper contains any figures and you haven't removed/disabled
%%% them in the LaTeX source, you can remove the pages showing these figures
%%% from the PDF file. If you want to remove, say, pages 18 and 19 with
%%% "pdftk" (PDF toolkit), you could execute
%%%    pdftk original.pdf cat 1-17 20-end output manuscript.pdf
%%% While this needs some extra effort, it has the advantage (compared to
%%% removing the figures in the LaTeX source) that references to figures
%%% with \ref{} still work.
