%
% Available class options
% e.g., \documentclass[10pt,conference]{IEEEtran}
%
% *** choose only one from each category ***
%
% 9pt, 10pt, 11pt, 12pt
% Sets normal font size. The default is 10pt.
%
% conference, journal, technote, peerreview, peerreviewca
% determines format mode - conference papers, journal papers,
% correspondence papers (technotes), or peer review papers. The user
% should also select 9pt when using technote. peerreview is like
% journal mode, but provides for a single-column "cover" title page for
% anonymous peer review. The paper title (without the author names) is
% repeated at the top of the page after the cover page. For peer review
% papers, the \IEEEpeerreviewmaketitle command must be executed (will
% automatically be ignored for non-peerreview modes) at the place the
% cover page is to end, usually just after the abstract (keywords are
% not normally used with peer review papers). peerreviewca is like
% peerreview, but allows the author names to be entered and formatted
% as with conference mode so that author affiliation and contact
% information can be easily seen on the cover page.
% The default is journal.
%
% draft, draftcls, draftclsnofoot, final
% determines if paper is formatted as a widely spaced draft (for
% handwritten editor comments) or as a properly typeset final version.
% draftcls restricts draft mode to the class file while all other LaTeX
% packages (i.e., \usepackage{graphicx}) will behave as final - allows
% for a draft paper with visible figures, etc. draftclsnofoot is like
% draftcls, but does not display the date and the word "DRAFT" at the foot
% of the pages. If using one of the draft modes, the user will probably
% also want to select onecolumn.
% The default is final.
%
% letterpaper, a4paper, cspaper
% determines paper size: 8.5in X 11in, 210mm X 297mm or 7.875in X 10.75in.
% Changing the paper size in the standard journal and conference modes
% will not alter the typesetting of the document - only the margins will
% be affected. In particular, documents using the a4paper option will
% have reduced side margins (A4 is narrower than US letter) and a longer
% bottom margin (A4 is longer than US letter). For both cases, the top
% margins will be the same and the text will be horizontally centered.
% For the compsoc conference and draft modes, it is the margins that will
% remain constant, and thus the text area size will vary, with changes in
% the paper size.
% The cspaper option is the special ``trim'' paper size (7.875in x 10.75in)
% used in the actual publication of Computer Society journals. Under
% compsoc journal mode, this option does not alter the typesetting of the
% document. Authors should invoke the cspaper option only if requested to
% do so by the editors of the specific journal they are submitting to.
% For final submission to the IEEE, authors should generally use US letter
% (8.5 X 11in) paper unless otherwise instructed. Note that authors should
% ensure that all post-processing (ps, pdf, etc.) uses the same paper
% specificiation as the .tex document. Problems here are by far the number
% one reason for incorrect margins. IEEEtran will automatically set the
% default paper size under pdflatex (without requiring any change to
% pdftex.cfg), so this issue is more important to dvips users. Fix
% config.ps, config.pdf, or ~/.dvipsrc for dvips, or use the
% dvips -t papersize option instead as needed. For the cspaper option,
% the corresponding dvips paper name is "ieeecs".
% See the testflow documentation
% http://www.ctan.org/tex-archive/macros/latex/contrib/IEEEtran/testflow
% for more details on dvips paper size configuration.
% The default is letterpaper.
%
% oneside, twoside
% determines if layout follows single sided or two sided (duplex)
% printing. The only notable change is with the headings at the top of
% the pages.
% The default is oneside.
%
% onecolumn, twocolumn
% determines if text is organized into one or two columns per page. One
% column mode is usually used only with draft papers.
% The default is twocolumn.
%
% comsoc, compsoc, transmag
% Use the format of the IEEE Communications Society, IEEE Computer Society
% or IEEE Transactions on Magnetics, respectively.
%
% romanappendices
% Use the "Appendix I" convention when numbering appendices. IEEEtran.cls
% now defaults to Alpha "Appendix A" convention - the opposite of what
% v1.6b and earlier did.
%
% captionsoff
% disables the display of the figure/table captions. Some IEEE journals
% request that captions be removed and figures/tables be put on pages
% of their own at the end of an initial paper submission. The endfloat

% V1.6, we are now going to fine tune the interword spacing
% The default interword glue for Times under TeX appears to use a
% nominal interword spacing of 25% (relative to the font size, i.e., 1em)
% a maximum of 40% and a minimum of 19%.
% For example, 10pt text uses an interword glue of:
%
% 2.5pt plus 1.49998pt minus 0.59998pt
%
% However, the IEEE allows for a more generous range which reduces the need
% for hyphenation, especially for two column text. Furthermore, the IEEE
% tends to use a little bit more nominal space between the words.
% The IEEE's interword spacing percentages appear to be:
% 35% nominal
% 23% minimum
