%%%% Load the package 'doublesp' which allows line spacing
%%%% to be better controlled. Sets the linespacing to 2

\RequirePackage{/home/erm/tex/doublesp}%
\setstretch{2}%

%%%% Load the four packages: 'ifthen', 'theorem', 'indentfi' and 'endnotes'.
%%%% 'ifthen' provides some conditioning commands which are used below.
%%%% 'theorem' allows one to customize the display of theorems.
%%%% 'indentfi' forces the first paragraph to be indented.
%%%% 'endnotes' provides commands to convert footnotes into endnotes.

\RequirePackage{ifthen,theorem,/home/erm/tex/indentfi} %,endnotes}

%%%% The following commands by Pawel Stryszak change
%%%% the amount of paragraph indentation for endnotes,
%%%% make footnotes act as endnotes, and provides the
%%%% heading for the endnotes (with a minor modification
%%%% by GLW).

%%%% Change has been made in Version 3 to correct
%%%% the vertical positioning of the 'Notes' heading.
%%%% Similar change made in appendix code for
%%%% 'Appendix Notes'
