     2  %% IEEEtran.cls 2011/11/03 version V1.8 based on
     3  %% IEEEtran.cls 2007/03/05 version V1.7a
     4  %% The changes in V1.8 are made with a single goal in mind:
     5  %% to change the look of the output using the [conference] option
     6  %% and the default font size (10pt) to match the Word template more closely.
     7  %% These changes may well have undesired side effects when other options
     8  %% are in force!

    84  % Available class options 
    85  % e.g., \documentclass[10pt,conference]{IEEEtran} 
    86  % 
    87  %             *** choose only one from each category ***
    88  %
    89  % 9pt, 10pt, 11pt, 12pt
    90  %    Sets normal font size. The default is 10pt.
    91  % 
    92  % conference, journal, technote, peerreview, peerreviewca
    93  %    determines format mode - conference papers, journal papers,
    94  %    correspondence papers (technotes), or peer review papers. The user
    95  %    should also select 9pt when using technote. peerreview is like
    96  %    journal mode, but provides for a single-column "cover" title page for
    97  %    anonymous peer review. The paper title (without the author names) is
    98  %    repeated at the top of the page after the cover page. For peer review
    99  %    papers, the \IEEEpeerreviewmaketitle command must be executed (will
   100  %    automatically be ignored for non-peerreview modes) at the place the
   101  %    cover page is to end, usually just after the abstract (keywords are
   102  %    not normally used with peer review papers). peerreviewca is like
   103  %    peerreview, but allows the author names to be entered and formatted
   104  %    as with conference mode so that author affiliation and contact
   105  %    information can be easily seen on the cover page.
   106  %    The default is journal.
   107  %
   108  % draft, draftcls, draftclsnofoot, final
   109  %    determines if paper is formatted as a widely spaced draft (for
   110  %    handwritten editor comments) or as a properly typeset final version.
   111  %    draftcls restricts draft mode to the class file while all other LaTeX
   112  %    packages (i.e., \usepackage{graphicx}) will behave as final - allows
   113  %    for a draft paper with visible figures, etc. draftclsnofoot is like
   114  %    draftcls, but does not display the date and the word "DRAFT" at the foot
   115  %    of the pages. If using one of the draft modes, the user will probably
   116  %    also want to select onecolumn.
   117  %    The default is final.
   118  %
   119  % letterpaper, a4paper
   120  %    determines paper size: 8.5in X 11in or 210mm X 297mm. CHANGING THE PAPER
   121  %    SIZE WILL NOT ALTER THE TYPESETTING OF THE DOCUMENT - ONLY THE MARGINS
   122  %    WILL BE AFFECTED. In particular, documents using the a4paper option will
   123  %    have reduced side margins (A4 is narrower than US letter) and a longer
   124  %    bottom margin (A4 is longer than US letter). For both cases, the top
   125  %    margins will be the same and the text will be horizontally centered. 
   126  %    For final submission to IEEE, authors should use US letter (8.5 X 11in)
   127  %    paper. Note that authors should ensure that all post-processing 
   128  %    (ps, pdf, etc.) uses the same paper specificiation as the .tex document.
   129  %    Problems here are by far the number one reason for incorrect margins.
   130  %    IEEEtran will automatically set the default paper size under pdflatex 
   131  %    (without requiring a change to pdftex.cfg), so this issue is more
   132  %    important to dvips users. Fix config.ps, config.pdf, or ~/.dvipsrc for
   133  %    dvips, or use the dvips -t papersize option instead as needed. See the
   134  %    testflow documentation
   135  %    http://www.ctan.org/tex-archive/macros/latex/contrib/IEEEtran/testflow
   136  %    for more details on dvips paper size configuration.
   137  %    The default is letterpaper.
   138  %
   139  % oneside, twoside
   140  %    determines if layout follows single sided or two sided (duplex)
   141  %    printing. The only notable change is with the headings at the top of
   142  %    the pages.
   143  %    The default is oneside.
   144  %
   145  % onecolumn, twocolumn
   146  %    determines if text is organized into one or two columns per page. One
   147  %    column mode is usually used only with draft papers.
   148  %    The default is twocolumn.
   149  %
   150  % compsoc
   151  %    Use the format of the IEEE Computer Society.
   152  %
   153  % romanappendices
   154  %    Use the "Appendix I" convention when numbering appendices. IEEEtran.cls
   155  %    now defaults to Alpha "Appendix A" convention - the opposite of what
   156  %    v1.6b and earlier did.
   157  %
   158  % captionsoff
   159  %    disables the display of the figure/table captions. Some IEEE journals
   160  %    request that captions be removed and figures/tables be put on pages
   161  %    of their own at the end of an initial paper submission. The endfloat
   162  %    package can be used with this class option to achieve this format.
   163  %
   164  % nofonttune
   165  %    turns off tuning of the font interword spacing. Maybe useful to those
   166  %    not using the standard Times fonts or for those who have already "tuned"
   167  %    their fonts.
   168  %    The default is to enable IEEEtran to tune font parameters.

   646  % a maximum of 40% and a minimum of 19%.

   649  % 2.5pt plus 1.49998pt minus 0.59998pt
   650  % 
   651  % However, IEEE allows for a more generous range which reduces the need
   652  % for hyphenation, especially for two column text. Furthermore, IEEE
   653  % tends to use a little bit more nominal space between the words.
   654  % IEEE's interword spacing percentages appear to be:
   655  % 35% nominal
   656  % 23% minimum
   657  % 50% maximum

  1512  % determines the height of an invisible strut that is placed
  1513  % *above* the baseline of footnotes after the first. Since
  1514  % LaTeX considers the space for characters to be 0.7/baselineskip
  1515  % above the baseline and 0.3/baselineskip below it, we need to
  1516  % use 0.7/baselineskip as a \footnotesep to maintain equal spacing
  1517  % between all the lines of the footnotes. IEEE often uses a tad
  1518  % more, so use 0.8\baselineskip. This slightly larger value also helps
  1519  % the text to clear the footnote marks. Note that \thanks in IEEEtran
  1520  % uses its own value of \footnotesep which is set in \maketitle.
