+%%% LaTeX class for manuscripts submitted to the
+%%% Journal of Rural Studies (JRurStud)
+%%%
+%%% author: Arne Henningsen
+%%% version: 1.0 (16 April 2008)
+%%% license: LaTeX Project Public License 
+%%%
+%%% Note: This is an unofficial style file that may not fully comply
+%%% with the JRurStud formatting instructions in every detail.
+%%% Please report any problems to <ahenningsen<at>email<dot>uni-kiel<dot>de>.
+%%% Further information is available at
+%%% http://www.uni-kiel.de/agrarpol/ahenningsen/latex-bibtex.html
+%%%
+%%% This document class is based on the "scrartcl" class
+%%% from the KOMA script bundle.
+%%% Following additional packages are required:
+%%% amsmath, babel, csquotes, endfloat, endnotes fontenc, geometry
+%%% ifthen, inputenc, 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 5 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 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.

+%%% LaTeX class for manuscripts submitted to the
+%%% Journal "Regional Studies" (regstud)
+%%%
+%%% author: Arne Henningsen
+%%% version: 1.0 (14 January 2008)
+%%% license: LaTeX Project Public License 
+%%%
+%%% Note: This is an unofficial style file that may not fully comply
+%%% with the Formatting Instructions of the "Regional Studies" in every detail.
+%%% Please report any problems to
+%%% ahenningsen <at> email <dot> uni-kiel <dot> de.
+%%% Further information is available at
+%%% http://www.uni-kiel.de/agrarpol/ahenningsen/latex-bibtex.html
+%%%
+%%% This document class is based on the "scrartcl" class
+%%% from the KOMA script bundle.
+%%% Following additional packages are required:
+%%% amsmath, babel, csquotes, endfloat, endnotes, fontnec, geometry,
+%%% ifthen, inputenc, natbib, setspace, soul, titlesec, url, verbatim
+%%%
+%%% The corresponding BibTeX style file "regstud.bst" should be used
+%%% for the bibliography: \bibliographystyle{regstud}
+%%%
+%%% The document class provides following options:
+%%% noendfloat - don't move floats to the end of the paper
+%%% hidefloats - hide all floats (figures and tables)
+%%% author - show name(s) of authors(s)
+%%% date - show date
+%%%
+%%% This document class provides 3 new commands:
+%%% \keywords can be used to show keywors below the abstract
+%%% \jelclass can be used to show JEL classifications below the abstract
+%%% \affiliation can be used spefify the affiliation(s) of the author(s)
+%%%
+%%% If you use footnotes, add following line before the reference section:
+%%%    \listofendnotes
+%%%
+%%% To prepare a manuscript without floats, you can use
+%%% either option "hidefloats" to hide all floats
+%%% or extract the pages that do not include the floats
+%%% with "pdftk", e.g. "pdftk all.pdf cat 1-14 output main.pdf"
+%%% The former has the drawback that references to the hidden floats
+%%% with \ref{} are no longer possible.
+%%% The figures and tables can be extracted as images, e.g. with kpdf.
