% \section{Preface to Version 3}
%
% The \textsf{geometry} package becomes even more flexible and powerful with
% the release of version 3. This new release contains major changes and
% enhancements in user interface, calculation schemes and the default settings
% of the page dimensions.
% \begin{itemize}
%  \item \textbf{New default layout.}\par
%  The `automatic' centering is no longer default layout. Instead of
%  centering, the idea of margin ratio and common values for default settings
%  are introduced: the ratio of left (inner) margin to right (outer) margin
%  is set 1:1 (2:3 for twoside), and the ratio of top to bottom is set 2:3.
%  The margin ratios can be specified by newly introduced options,
%  e.g. |marginratio| (see Section~\ref{sec:completion} and \ref{sec:margin}
%  for the detail). In addition, the spaces for the head and foot of the
%  page are disregarded in calculating the placement of the text area by
%  default. Furthermore the default |scale| of the type area is set to
%  |0.7| with 70\% of the width and height of the paper. 
%  If you want to use the old default layout of version 2.3 or earlier,
%  add |compat2| as a first option, e.g., 
%  |\usepackage[compat2,left=1.5in]{geometry}|, which sets
%  the old default options 
%  \texttt{[scale=\{0.8,0.9\}, centering, includeheadfoot]} and allows
%  the subsequent options to behave as if they are used in the old version.
%  See also Section~\ref{sec:default} for the detail of the default layout. 
%
%  \item \textbf{Option |twosideshift| is obsoleted.} \par
%  |twoside| and other geometry options can substitute for it. 
%  A new option |bindingoffset| might be also helpful to control margins for 
%  oneside/twoside. For the detail, see Section~\ref{sec:margin}.
%
%  \item \textbf{Option |includemp| becomes independent of |marginparwidth|
%  and |marginparsep|.} \par
%  In the previous version, |marginparwidth| or |marginparsep| 
%  automatically set |includemp=true|. Now if you want |includemp| mode,
%  |includemp| should be set explicitly.
%
%  \item \textbf{Options |nohead|, |nofoot| and |noheadfoot| become
%  order-dependent and overwritable} \par
%  In the previous version, these options was order-independent:
%  |nohead,headsep=10pt| resulted in just |nohead| (\cs{headsep}|=0pt|,
%  \cs{headheight}|=0pt|), for example. But now they are overwritable 
%  by subsequent options. The above case results in \cs{headheight}|=0pt|
%  and \cs{headsep}|=10pt|.
%
%  \item \textbf{A complete set of options |ignore*| and |include*| for
%  head, foot and marginpar.}\par
%  The previous version has only |includemp|, which denotes that the width
%  of marginpar is included in the total body width. 
%  Now |ignore|\{|head|, |foot|, |headfoot|, |mp|, |all|\} and 
%  |include|\{|head|, |foot|, |headfoot|, |all|\} are newly added.
%  If one of these |ignore*| is set, the corresponding space(s) are 
%  disregarded in auto-completion calculation. 
%  In version 3, |ignoreall| is set by default. So if you need to include
%  the spaces for the head, foot and marginpar, the corresponding |include*|
%  should be set explicitly. In addition, unlike the previous version, 
%  neither |reversemp|, |marginparwidth| nor |marginparsep| sets |includemp|
%  automatically.
%
%  \item \textbf{New option |lines|.}\par
%  The option enables users to specify \cs{textheight} by the number of
%  lines included in \cs{textheight}, e.g., |lines=20|.
%
%  \item \textbf{New option |heightrounded|.}\par
%  The option rounds \cs{textheight} to \textit{n}-times (\textit{n}:
%  an integer) of \cs{baselineskip} plus \cs{topskip} to avoid ``underfull
%  vbox'' in some cases.
%
%  \item \textbf{New option |screen|.}\par
%  To make presentation with PC and video projector, geometry option
%  |screen,centering| with `slide' documentclass would be the best choice.
%
%  \item \textbf{New option |asymmetric|.}\par
%  The option implements a twosided layout in which margins are not swapped
%  on alternate pages and the marginal notes stay always on the same side.
%
%  \item \textbf{New option |showframe|.}\par
%  The option displays visible frames for the text area and page, and lines
%  for the head and foot to check layout in detail. Therefore |showframe.sty|
%  is excluded from the \textsf{geometry} package distribution.
%
%  \item \textbf{New option |pass|.}\par
%  The option disables auto-layout and all of the geometry settings except
%  |verbose| and |showframe|. It can be used for checking out the page
%  layout of the documentclass, other packages and manual settings
%  without \textsf{geometry}. 
% \end{itemize}
% See the text for the detail. All the new and modified options in this
% release are marked with `$\star3$' and `$\dagger3$' respectively.
%
% \section{Introduction}
%
% To set dimensions for page layout in \LaTeX\ is not straightforward. 
% You need to adjust several \LaTeX{} native dimensions to place a text area
% where you want
% If you want to center the text area in the paper you use, for example, 
% you have to specify native dimensions as follows:
% \begin{quote}
%    |\usepackage{calc}|\\
%    |\setlength\textwidth{7in}|\\
%    |\setlength\textheight{10in}|\\
%    |\setlength\oddsidemargin{(\paperwidth-\textwidth)/2 - 1in}|\\
%    |\setlength\topmargin{(\paperheight-\textheight|\\
%    |                      -\headheight-\headsep-\footskip)/2 - 1in}|.
% \end{quote}
% Without package \textsl{calc}, the above example would need
% more tedious settings. Package \textsf{geometry} provides an easy
% way to set page layout parameters. In this case, what you have to do
% is just
% \begin{quote}
%    |\usepackage[text={7in,10in},centering]{geometry}|. 
% \end{quote}
% Besides centering problem, setting margins from each edge of the paper is
% also troublesome. But \textsf{geometry} also make it easy.
% If you want to set each margin 1.5in, you can go 
% \begin{quote}
%    |\usepackage[margin=1.5in]{geometry}| 
% \end{quote}
% In both cases, the unspecified dimensions are automatically determined.
% The package will be also useful when you have to set page layout obeying
% the following strict instructions: for example,
% \begin{quote}\slshape
%   The total allowable width of the text area is 6.5 inches wide by 8.75
%   inches high. The top margin on each page should be 1.2 inches from
%   the top edge of the page. The left margin should be 0.9 inch from 
%   the left edge. The footer with page number should be at the bottom
%   of the text area.
% \end{quote}
% In this case, using \textsf{geometry} you can go 
% \begin{quote}
% |\usepackage[total={6.5in,8.75in},|\\
% |            top=1.2in, left=0.9in, includefoot]{geometry}|.
% \end{quote}
%
% Setting a text area on the paper in document preparation system has some
% analogy to placing a window on the background in the window system. 
% The name `geometry' comes from the |-geometry| option used for specifying
% a size and location of a window in X Window System.
%
% \section{Page Geometry}
% \subsection{Layout Dimensions}
% To realize a straightforward setting for page layout, the following page
% structure is introduced: A paper contains a total body (printable area)
% and margins. The total body consists of a body (text area) with optional
% a header, a footer and marginal notes (marginpar). There are four margins:
% the left, right, top and bottom margins. For twosided documents, horizontal
% margins should be called the inner and outer margins.
% \begin{quote}
%  \begin{tabular}{rcl}
%   \gpart{paper}&:&\gpart{total body} and
%   \gpart{margins}\\
%   \gpart{total body}&:&\gpart{body} (text area)\quad
%             (optional \gpart{head}, \gpart{foot} and \gpart{marginpar})\\
%   \gpart{margins}&:&\gpart{left}(\gpart{inner}), 
%      \gpart{right}(\gpart{outer}), \gpart{top} and \gpart{bottom}
%   \end{tabular}
% \end{quote}
% Each margin is measured from the corresponding edge of a paper. 
% For example, left margin (inner margin) means a horizontal distance
% between the left (inner) edge of the paper and that of the total body.
% Therefore the left and top margins defined in \textsf{geometry}
% are different from the native dimensions \cs{leftmargin}
% and \cs{topmargin}.
% The size of a body (text area) can be modified by \cs{textwidth} and
% \cs{textheight}. 
%
% The layout parts and the corresponding dimension names used in this
% package are showed schematically in Figure~\ref{fig:layout}.

%  If margins on verso pages are swapped by |twoside| option,

% The dimensions for paper, total body and margins have the following
% relations.
% \begin{eqnarray}
%  \label{eq:paperwidth}
%  |paperwidth| &=& |left|+|width|+|right| \\
%  |paperheight| &=& |top|+|height|+|bottom|
%  \label{eq:paperheight}
% \end{eqnarray}
% The dimensions of the total body, |width| and |height|, are defined
% as follows:
% \begin{eqnarray}
%  \label{eq:width}
%  |width| &:=& |textwidth| \quad( +  |marginparsep| + |marginparwidth| )\\
%  |height| &:=& |textheight| \quad(+ |headheight| + |headsep| + |footskip| )
%  \label{eq:height}
% \end{eqnarray}
% In Equation (\ref{eq:width}), |width:=textwidth| by default, 
% but |marginparsep| and |marginparwidth| are included in |width|
% if |includemp| option is set |true|. 
% In Equation (\ref{eq:height}), |height:=textheight| by default. 
% If |includehead| is set to |true|, |headheight| and |headsep| are
% considered as a part of |height| in the the vertical completion calculation.
% In the same way, |includefoot| includes
% |footskip|. Note that options |ignore*| just exclude the corresponding
% spaces from |textheight|, but do not change those lengths themselves.
% Figure~\ref{fig:includes} shows how these options work.

% \subsection{Auto-Completion Scheme}\label{sec:completion}
%
% Suppose that the paper size is pre-defined in Equation~(\ref{eq:paperwidth})
% or (\ref{eq:paperheight}), if two dimensions out of the three dimensions
% in the right-hand side of each equation are specified,  the rest of the
% dimensions can be determined by the specified ones. However, when none or
% only one of the three dimensions is specified, the rest of the dimensions
% can't generally be determined without some assumptions. 
%
% The \textsf{geometry} package has an auto-completion scheme with some
% default parameters to determine the unspecified dimensions independently
% for each direction. If the size of \gpart{total body} (i.e., |width| in
% the horizontal direction) is specified, the margins (|left| and |right|)
% can be determined with a default ratio of one margin to the other
% (|left/right|).
% If one margin is specified, the rest of dimensions can also be determined
% by the default margin ratio. 
% Page margin setting by margin ratio was introduced in KOMA 
% script\footnote{CTAN:~\texttt{macros/latex/contrib/supported/koma-script}
% by Frank Neukam and Markus Kohm.}.
%
% The default vertical margin ratio is $2/3$, namely,
% \begin{equation}
%  |top| : |bottom| = 2 : 3 \qquad\textit{default}.
% \end{equation}
% As for the horizontal margin ratio, the default value depends on
% whether the document is onesided or twosided,
% \begin{equation}
%  |left|\;(|inner|) : |right|\;(|outer|) 
%       = \left\{ \begin{array}{ll}
%              1 : 1 \qquad\textit{default for oneside},\\
%              2 : 3 \qquad\textit{default for twoside}.
%         \end{array}\right.
% \end{equation}
% Obviously the default horizontal margin ratio for oneside is `centering'.
%
% For example, if one specifies |right=2.4cm| with a \textit{twosided}
% layout in A4 paper (21.0cm$\times$29.7cm), unspecified |left| and |width|
% are automatically determined using the default horizontal margin ratio
% (2/3) as follows:
% \begin{eqnarray}
%      |left| &=& \langle\textsf{horizontal-margin-ratio}\rangle
%                 \times |right| \nonumber\\
%             &=& |2/3| \times |2.4cm| = |1.6cm|\\[1ex]
%    |width|  &=& |paperwidth| - |left| - |right| \nonumber\\
%             &=& |21.0cm| - |1.6cm| - |2.4cm|  = |17.0cm|.
% \end{eqnarray}
% In this case, the vertical dimensions |top|, |height| and |bottom|
% are determined by the default vertical margin ratio with 2:3
% and the default size of \gpart{total body} with 70\% of the paper height:
% \begin{eqnarray}\displaystyle
%   |height| &=&  |0.7| \times |paperheight|\nonumber\\
%            &=&  |0.7| \times |29.7cm| = |20.79cm| \\[1ex]
%   |top|    &=& \frac{\langle\textsf{vertical-margin-ratio}\rangle}
%                     {1+\langle\textsf{vertical-margin-ratio}\rangle}
%                \times (|paperheight| - |height|) \nonumber\\
%            &=& \frac{2}{2+3}\times(|29.7cm| - |20.79cm|)\nonumber\\[1ex]
%            &=& 0.4\times |8.91cm| = |3.564cm|\\[2ex]
%   |bottom| &=& 0.6\times |8.91cm| = |5.346cm|
% \end{eqnarray}
%
% The auto-completion rules are shown in Table~\ref{tab:completion}
% and Equation~(\ref{eq:completion}).
% $A$, $B$ and $C$ in Table~\ref{tab:completion} are user-specified values,
% $*$ denotes unspecified ones. The right-hand side table shows the
% corresponding results of auto-completion. The unspecified values can be
% determined by $A$, $B$ and $L$ (|paperwidth| or |paperheight|).
% In Table~\ref{tab:completion}, functions ${\cal R}(x)$ and ${\cal M}(x)$
% are defined as follows:
% \begin{equation}
%  \begin{array}{rcl}
%    {\cal R}(x) &=& L-x\\
%    {\cal M}(x) &=& {\cal R}(x)\;/\;(1+\sigma)\\
%  \end{array}
%  \label{eq:completion}
% \end{equation}
% Here $\sigma$ denotes the ratio of left margin (inner) to right margin
% (outer) or the ratio of top to bottom. To set $\sigma$ as a geometry option,
% you can use \{|h|,|v|\}|marginratio| options with |a:b|-type value,
% for example, |hmarginratio=2:3|. 
% \begin{eqnarray}
%  \label{eq:hratios}
%  |hmarginratio| &=& |left| : |right|\\
%  |vmarginratio| &=& |top| : |bottom|
%  \label{eq:vratios}
% \end{eqnarray}
% By default, $\sigma$ is 1/1 (=1) for oneside and 2/3 for twoside
% in the horizontal direction, and 2/3 in the vertical.
% If none of three dimensions is specified in each direction, the default
% setting is used: width and height is set to 70\% of the paper width 
% and height respectively. If all the three dimensions would be specified,
% margins remain and width or height is ignored.

% \section{User Interface}
% \subsection{General Features}
%
% The geometry options using the \textsf{keyval} interface
% `\meta{key}=\meta{value}' can be set either in the optional argument to
% the \cs{usepackage} command, or in the argument of the
% \cs{geometry} macro. This macro, if necessary, should be used only in the
% preamble, i.e., before |\begin{document}|.
% In either case, the argument consists of a list of
% comma-separated \textsf{keyval} options.
% The main features of setting options are listed below.
% \begin{itemize}\itemsep=0pt
% \item Multiple lines are allowed. (But blank lines are not allowed.)
% \item Any spaces between words are ignored.
% \item Options are basically order-independent.\\
% (There are some exceptions. See Section~\ref{sec:order-depend}
%  for details.)
% \end{itemize}
%  For example,
% \begin{quote}
% |\usepackage[ a5paper ,  hmargin = { 3cm,|\\
% |                .8in } , height|\\
% |         =  10in ]{geometry}|
% \end{quote}
% is equivalent to 
% \begin{quote}
%   |\usepackage[height=10in,a5paper,hmargin={3cm,0.8in}]{geometry}|
% \end{quote}
% Some options are allowed to have sub-list, e.g. |{3cm,0.8in}|.
% Note that the order of values in the sub-list is significant.
% The above setting is also equivalent to the followings:
% \begin{quote}
%   |\usepackage{geometry}|\\
%   |\geometry{height=10in,a5paper,hmargin={3cm,0.8in}}|
% \end{quote}
% or 
% \begin{quote}
%   |\usepackage[a5paper]{geometry}|\\
%   |\geometry{hmargin={3cm,0.8in},height=8in}|\\
%   |\geometry{height=10in}|.
% \end{quote}
% Thus, multiple use of \cs{geometry} just appends options.
%
% \textsf{Geometry} supports package 
% \textsl{calc}\footnote{CTAN:~\texttt{macros/latex/required/tools}}.
% For example,
% \begin{quote}
%   |\usepackage{calc}|\\
%   |\usepackage[textheight=20\baselineskip+10pt]{geometry}|
% \end{quote}
%
% \subsection{Option Types}
% \textsf{Geometry} options are categorized into four types:
%
% \begin{enumerate}\itemsep=0pt
% \item \textbf{Boolean type}
%
%    takes a boolean value (|true| or |false|). If no value,
%    |true| is set by default.
%    \begin{quote}
%       \meta{key}|=true|\OR|false|.\\
%       \meta{key} with no value is equivalent to 
%       \meta{key}|=true|.
%    \end{quote}
%    \textit{Examples:}~ |verbose=true|, |includehead|, 
%    |twoside=false|.\\
%    Paper name is the exception. The preferred paper name should be set
%    with no values. Whatever value is given, it is ignored. For
%    instance, |a4paper=XXX| is equivalent to |a4paper|.
%
% \item \textbf{Single-valued type}
%
%    takes a mandatory value.
%    \begin{quote}
%    \meta{key}|=|\meta{value}.
%    \end{quote}
%    \textit{Examples:}~ |width=7in|, |left=1.25in|,
%    |footskip=1cm|, |height=.86\paperheight|.
%
% \item \textbf{Double-valued type}
%
%    takes a pair of comma-separated values in braces. The two values can
%    be shortened to one value if they are identical.
%    \begin{quote}
%    \meta{key}|=|\argii{value1}{value2}.\\
%    \meta{key}|=|\meta{value} is equivalent to 
%              \meta{key}|=|\argii{value}{value}.
%    \end{quote}
%    \textit{Examples:}~ |hmargin={1.5in,1in}|, |scale=0.8|,
%    |body={7in,10in}|.
%
% \item \textbf{Triple-valued type}
%
%    takes three mandatory, comma-separated values in braces.
%    \begin{quote}
%    \meta{key}|=|\argiii{value1}{value2}{value3}
%    \end{quote}
%    Each value must be a dimension or null. When you give an empty value
%    or `|*|', it means null and leaves the appropriate value 
%    to the auto-completion mechanism. You need to specify at least one
%    dimension, typically two dimensions. You can set nulls for all the 
%    values, but it makes no sense.
%    \textit{Examples:}\\
%    \hspace*{2em} |hdivide={2cm,*,1cm}|, |vdivide={3cm,19cm, }|,
%                   |divide={1in,*,1in}|.
% \end{enumerate}
%
% \section{Option Specification}
%
% This section describes all the options provided by \textsf{geometry}.
%
% \subsection{Paper Size}
% 
% The options below set paper/media size and orientation.
% \begin{Options}
% \item[paper\OR papername] ~\\ 
%    specifies a paper name. The paper names available in \textsf{geometry}.
%    |paper=|\meta{paper-name}. For example |paper=a4paper|, which is 
%    equivalent to just |a4paper|.
% \item[\vtop{
%  \hbox{a0paper, a1paper, a2paper, a3paper, a4paper, a5paper, a6paper}
%  \hbox{b0paper, b1paper, b2paper, b3paper, b4paper, b5paper, b6paper}
%  \hbox{letterpaper, executivepaper, legalpaper}}]~\\[1ex] 
%    specifies paper name. They can typically be used with no values.
%    Note that whatever value (even |false|) is given to this option, the
%    value will be ignored. For example, the followings have the same effect:
%    |a5paper|, |a5paper=true|, |a5paper=false| and |a5paper=XXXX|.
% \item[\New{3}screen] a special paper size with (W,H) = (225mm,180mm).
%    For presentation with PC and video projector, ``|screen,centering|''
%    with `slide' documentclass would be useful.
% \item[paperwidth] width of the paper. |paperwidth=|\meta{length}.
% \item[paperheight] height of the paper. |paperheight=|\meta{length}.
% \item[papersize] width and height of the paper.\\
%    |papersize=|\argii{width}{height} or |papersize=|\meta{length}.
% \item[landscape] switches the paper orientation to landscape mode.
% \item[portrait] switches the paper orientation to portrait mode.
%    This is equivalent to |landscape=false|.
% \end{Options}
%
% Options for paper names (e.g., |a4paper|) and orientation
% (|portrait| and |landscape|) can be set as document class options. 
% For example, you can set |\documentclass[a4paper,landscape]{article}|, 
% then |a4paper| and |landscape| are processed in \textsf{geometry} as well.
% This is also the case for |twoside| and |twocolumn|
% (see also Section~\ref{sec:dimension}).
%
% \subsection{Body Size}\label{sec:body}
%
% The options specifying the size of \gpart{total body} are described in this
% section.
% \begin{Options}
% \item[hscale]
%    ratio of width of \gpart{total body} to \cs{paperwidth}. 
%    |hscale=|\meta{h-scale}, e.g., |hscale=0.8| is equivalent to
%    |width=0.8|\cs{paperwidth}. (|0.7| by default)
% \item[vscale]
%    ratio of height of \gpart{total body} to \cs{paperheight}, e.g.,
%    |vscale=|\meta{v-scale}. (|0.7| by default) |vscale=0.9| is equivalent
%    to |height=0.9|\cs{paperheight}.
% \item[scale] ratio of \gpart{total body} to the paper.
%    |scale=|\argii{h-scale}{v-scale} or |scale=|\meta{scale}.
%    (|0.7| by default)
% \item[width\OR totalwidth] ~\\
%    width of \gpart{total body}. |width=|\meta{length} or
%    |totalwidth=|\meta{length}. This dimension should not be confused with
%    |textwidth|. Generally, |width| $\ge$ |textwidth| because |width|
%    includes the width of the marginal notes if |includemp| is set to |true|.
%    If |textwidth| and |width| are specified at the same time, |width| is
%    ignored.
% \item[height\OR totalheight] ~\\
%    height of \gpart{total body}, excluding header and footer by default.
%    If |includehead| or |includefoot| is set, |height| includes
%    the head or foot of the page as well as |textheight|.
%    |height=|\meta{length} or |totalheight=|\meta{length}. If both
%    |textheight| and |height| are specified, |height| will be ignored.
% \item[total] width and height of \gpart{total body}.\\
%    |total=|\argii{width}{height} or |total=|\meta{length}.
% \item[textwidth] modifies \cs{textwidth}, the width of \gpart{body} 
%    (the text are). |textwidth=|\meta{length}.
% \item[textheight] modifies \cs{textheight}, the height of \gpart{body}.
%    |textheight=|\meta{length}.
% \item[text\OR body] sets both \cs{textwidth} and \cs{textheight} of the body
%    of page. |body=|\argii{width}{height} or |text=|\meta{length}.
% \item[\New{3}lines] enables users to specify \cs{textheight} by the number
%    of lines. |lines|=\meta{integer}.
% \item[\New{3}includehead] includes the head of the page, \cs{headheight}
%    and \cs{headsep}, into \gpart{total body}. It is set to |false| by
%    default. It is opposite to |ignorehead|. See Figure~\ref{fig:includes}.
% \item[\New{3}includefoot] includes the foot of the page, \cs{footskip},
%    into \gpart{body}. It is opposite to |ignorefoot|.
%    It is |false| by default. See Figure~\ref{fig:includes}.
% \item[\New{3}includeheadfoot]~\\ 
%    sets both |includehead| and |includefoot| to |true|, which is opposite
%    to |ignoreheadfoot|. See Figure~\ref{fig:includes}.
% \item[\Mod{3}includemp] includes the margin notes,  \cs{marginparwidth}
%    and \cs{marginparsep}, into \gpart{body} when calculating horizontal
%    calculation. In version 3, |includemp| is independent of options 
%    |marginparwidth| and |marginparsep|, and set to |false| by default.
% \item[\New{3}includeall] sets both |includeheadfoot| and |includemp| to
%    |true|. See Figure~\ref{fig:includes} and Figure~\ref{fig:modes}.
% \item[\New{3}ignorehead] disregards the head of the page,
%    |headheight| and |headsep|, in determining vertical layout, but does not
%    change those lengths. It is equivalent to |includehead=false|. It is set
%    to |true| by default. See also |includehead|.
% \item[\New{3}ignorefoot] disregards the foot of page, |footskip|,
%    in determining vertical layout, but does not change that length.
%    This option is set to |true| by default. See also |includefoot|.
% \item[\New{3}ignoreheadfoot]~\\ sets both |ignorehead| and |ignorefoot|
%    to |true|. See also |includeheadfoot|.
% \item[\New{3}ignoremp] disregards the marginal notes in determining the
%    horizontal margins (|true| is set by default). If marginal notes fall off
%    the page, the warning message will be displayed when |verbose=true|.
%    See also Figure~\ref{fig:modes} and |includemp|.
% \item[\New{3}ignoreall] sets both |ignoreheadfoot| and |ignoremp| to |true|. 
%    See also |includeall|.
% \item[\New{3}heightrounded]~\\
%    This option rounds \cs{textheight} to \textit{n}-times (\textit{n}:
%    an integer) of \cs{baselineskip} plus \cs{topskip} to avoid 
%    ``underfull vbox'' in some cases. For example, if \cs{textheight} is
%    486pt with \cs{baselineskip} 12pt and \cs{topskip} 10pt, then
%    \begin{quote}
%      $(39\times12\textrm{pt}+10\textrm{pt}=)\: 478\textrm{pt}
%       < 486\textrm{pt} < 
%      490\textrm{pt} \:(=40\times12\textrm{pt}+10\textrm{pt})$,
%    \end{quote}
%    as a result \cs{textheight} is rounded to 490pt. |heightrounded=false|
%    by default.
% \end{Options}
%
% The following options can specify body and margins simultaneously with
% three comma-separated values in braces.
% \begin{Options}
% \item[hdivide] horizontal partitions (left,width,right).
%   |hdivide=|\argiii{left margin}{width}{right margin}. 
%   Note that you should not specify all of the three parameters.
%   The best way of using this option is to specify two of three and 
%   leave the rest with null(nothing) or `|*|'. For example, when you set
%   |hdivide={2cm,15cm, }|, the margin from the right-side edge of page
%   will be determined calculating |paperwidth-2cm-15cm|.
% \item[vdivide] vertical partitions (top,height,bottom).
%   |vdivide=|\argiii{top margin}{height}{bottom margin}.
% \item[divide] |divide=|\vargiii{$A$}{$B$}{$C$} is interpreted  as 
%   |hdivide=|\vargiii{$A$}{$B$}{$C$} and |vdivide=|\vargiii{$A$}{$B$}{$C$}.
% \end{Options}
%
% \subsection{Margin Size}\label{sec:margin}
%
% The options specifying the size of visible margins are listed below.
% \begin{Options}
% \item[left\OR lmargin\OR inner]~\\
%    left margin (for oneside) or inner margin (for twoside) of 
%    \gpart{total body}. In other words, the distance between the left (inner)
%    edge of the paper and that of \gpart{total body}. |left=|\meta{length}.
%    |inner| has no special meaning, just an alias of |left| and |lmargin|.
% \item[right\OR rmargin\OR outer]~\\ 
%    right or outer margin of \gpart{total body}. |right=|\meta{length}.
% \item[top\OR tmargin] top margin of the page. |top=|\meta{length}.
%    Note this option has nothing to do with the native dimension
%    \cs{topmargin}.
% \item[bottom\OR bmargin]~\\ 
%    bottom margin of the page. |bottom=|\meta{length}.
% \item[hmargin] left and right margin.
%   |hmargin=|\argii{left margin}{right margin} or |hmargin=|\meta{length}.
% \item[vmargin] top and bottom margin.
%   |vmargin=|\argii{top margin}{bottom margin} or |vmargin=|\meta{length}.
% \item[margin] |margin=|\vargii{$A$}{$B$} is equivalent to 
%   |hmargin=|\vargii{$A$}{$B$} and |vmargin=|\vargii{$A$}{$B$}.
%   |margin=|$A$ is automatically expanded to |hmargin=|$A$ and |vmargin=|$A$.
% \item[\New{3}hmarginratio]
%   horizontal margin ratio of |left| (inner) to |right| (outer). 
%   The value of \meta{ratio} should be specified with colon-separated 
%   two values. Each value should be a positive integer less than 100
%   to prevent arithmetic overflow, e.g., |2:3| instead of |1:1.5|.
%   The default ratio is |1:1| for oneside, |2:3| for twoside.
% \item[\New{3}vmarginratio]
%    vertical margin ratio of |top| to |bottom|. The default ratio is |2:3|.
% \item[\New{3}marginratio\OR ratio]~\\
%    horizontal and vertical margin ratios.
%   |marginratio=|\argii{horizontal ratio}{vertical ratio} or
%   |marginratio=|\meta{ratio}.
% \item[\New{3}hcentering] sets auto-centering horizontally and is
%   equivalent to |hmarginratio=1:1|. It is set to |true| by default for
%   oneside. See also |hmarginratio|.
% \item[\New{3}vcentering] sets auto-centering vertically and is
%   equivalent to |vmarginratio=1:1|. The default is |false|.
%   See also |vmarginratio|.
% \item[\New{3}centering] sets auto-centering and is equivalent to
%   |marginratio=1:1|. See also |marginratio|. The default is |false|.
%   See also |marginratio|.
% \item[twoside] switches on twoside mode with left and right margins swapped
%   on verso pages. The option sets \cs{@twoside} and \cs{@mparswitch} 
%   switches. See also |asymmetric|.
% \item[\New{3}asymmetric] implements a twosided layout in which margins are
%   not swapped on alternate pages (by setting \cs{oddsidemargin} to 
%   \cs{evensidemargin} |+| |bindingoffset|) and in which the marginal notes
%   stay always on the same side. This option can be used as an alternative
%   to the twoside option. See also |twoside|.
% \item[\New{3}bindingoffset]~\\ removes a specified space 
%   from the lefthand-side of the page for oneside or the inner-side for
%   twoside. |bindingoffset=|\meta{length}. This is useful if pages 
%   are bound by a press binding (glued, stitched, stapled \ldots).
%   See Figure~\ref{fig:bindingoffset}.
% \item[hdivide] See description in Section~\ref{sec:body}.
% \item[vdivide] See description in Section~\ref{sec:body}.

% \subsection{Native Dimensions}\label{sec:dimension}
%
% The options below specify \LaTeX\ native dimensions and switches for page
% layout. See Figure~\ref{fig:layout}. Note that unlike version 2.3,
% |nohead|, |nofoot| and |noheadfoot| become overwritable, in other words,
% just shorthand for setting the corresponding LaTeX dimensions
% (\cs{headheight}, \cs{headsep} and \cs{footskip}) to 0pt.
%
% \begin{Options}
% \item[headheight\OR head]~\\
%    modifies \cs{headheight}, height of header.
%    |headheight=|\meta{length} or |head=|\meta{length}.
% \item[headsep] modifies \cs{headsep}, separation between header and text
%    (body). |headsep=|\meta{length}.
% \item[footskip\OR foot]~\\ modifies \cs{footskip}, distance separation
%    between baseline of last line of text and baseline of footer.
%    |footskip=|\meta{length} or |foot=|\meta{length}.
% \item[\Mod{3}nohead] eliminates spaces for the head of the page, which is
%    equivalent to both \cs{headheight}|=0pt| and \cs{headsep}|=0pt|.
% \item[\Mod{3}nofoot] eliminates spaces for the foot of the page, which is
%    equivalent to \cs{footskip}|=0pt|.
% \item[\Mod{3}noheadfoot] equivalent to |nohead| and |nofoot|.
% \item[footnotesep] changes the dimension \cs{skip}\cs{footins}, separation
%    between the bottom of text body and the top of footnote text.
%    \cs{headheight}|=0pt|, \cs{headsep}|=0pt| and \cs{footskip}|=0pt|.
% \item[\Mod{3}marginparwidth\OR marginpar]~\\ 
%    modifies \cs{marginparwidth}, width of the marginal notes.
%    |marginparwidth=|\meta{length}.
%    Unlike version 2.3, it does \textit{not} set |includemp=true|.
% \item[\Mod{3}marginparsep] modifies \cs{marginparsep}, separation between
%    body and marginal notes. |marginparsep=|\meta{length}.
%    Unlike version 2.3, it does \textit{not} set |includemp=true|.
% \item[\New{3}nomarginpar] shrinks spaces for marginal notes to 0pt, which
%    is equivalent to \cs{marginparwidth}|=0pt| and \cs{marginparsep}|=0pt|.
% \item[columnsep] modifies \cs{columnsep}, the separation between two
%    columns in |twocolumn| mode.
% \item[hoffset]  modifies \cs{hoffset}. |hoffset=|\meta{length}.
% \item[voffset]  modifies \cs{voffset}. |voffset=|\meta{length}.
% \item[offset] horizontal and vertical offset.\\
%    |offset=|\argii{hoffset}{voffset} or |offset=|\meta{length}.
% \item[twocolumn] sets |twocolumn| mode with \cs{@twocolumntrue}.
%   |twocolumn=false| denotes onecolumn mode with\cs{@twocolumnfalse}.
% \item[twoside] sets both \cs{@twosidetrue} and \cs{@mparswitchtrue}.
%   See Section~\ref{sec:margin}.
% \item[textwidth] sets \cs{textwidth} directly. See Section~\ref{sec:body}.
% \item[textheight] sets \cs{textheight} directly. See Section~\ref{sec:body}.
% \item[\New{3}reversemp\OR reversemarginpar]~\\
%   makes the marginal notes appear in the left (inner) margin with
%   \cs{@reversemargintrue}. Unlike version 2.3 or earlier,
%   it does \textit{not} change |includemp| mode. This is |false| by default.
% \end{Options}
%
% \subsection{Drivers}\label{sec:drivers}
% 
% Package \textsf{geometry} supports \textsl{dvips}, \textsl{dvipdfm},  
% \textsl{pdflatex} and \textsl{V\TeX} environment. These driver options are
% exclusive.
%
% \begin{Options}
% \item[\Mod{3}dvips] writes the paper size in dvi output with the \cs{special}
%     macro. If you use \textsl{dvips} as a DVI-to-PS driver,
%     for example, to print a document with |\geometry{a3paper,landscape}|
%     on A3 paper in landscape orientation, you don't need options
%     ``|-t a3 -t landscape|'' to \textsl{dvips}. 
%     In version 3, this option sets an addtional correction for landscape
%     documents so that PostScript outputs shouldn't be displayed upside down
%     by PostScript viewers, e.g., Ghostscript.
%     If you use \textsl{V\TeX} environment or \textsl{pdflatex} command,
%     this option is automatically deselected and changed to the corresponding
%     driver option.  This option works with xdvi and \textsl{dviout}
%     (though you may get some warnings).
% \item[\New{3}dvipdfm] works like |dvips| except landscape correction.
% \item[pdftex] sets \cs{pdfpagewidth} and \cs{pdfpageheight} properly
%     if \textsl{pdflatex} command is used for typeset. 
%     When \textsl{pdflatex} command is used, |pdftex| is automatically
%     selected. On the other hand when one is not using \textsl{pdflatex}
%     command this option is ineffective.
% \item[vtex] sets dimensions \cs{mediawidth} and \cs{mediaheight}
%     for \textsl{V\TeX}.
%     This option is automatically selected when one is using \textsl{V\TeX}
%     environment. On the other hand when one is not using \textsl{V\TeX}
%     this option is ineffective.
% \end{Options}
%
% Drivers options can be automatically changed depending on the typeset
% environment. 
% \begin{center}
%  \begin{tabular}{ll@{\quad$\rightarrow$\quad}ll}
%   environment & given driver option & resulted option \\\hline
%   \textsl{latex}    & |pdftex|~/~|vtex|   & \textit{none} \\
%   \textsl{pdflatex} & \textit{any}        & |pdftex|      \\
%   \textsl{V\TeX}    & \textit{any}        & |vtex|.       \\\hline
%  \end{tabular}
% \end{center}
%
% \subsection{Other Options}
%
%  The other useful options are described here.
% \begin{Options}
% \item[verbose] displays parameter results on the terminal.
%   |verbose=false| (default) still puts them into the log file.
% \item[reset] sets back the layout dimensions and switches to the
%   settings before \textsf{geometry} is loaded. Options given in 
%   |geometry.cfg| are also cleared.
%   Note that this cannot reset |pass| and |mag| with |truedimen|.
%   |reset=false| has no effect and cannot cancel the previous
%   |reset|(|=true|) if any. For example, when you go
%   \begin{quote}
%     |\documentclass[landscape]{article}|\\
%     |\usepackage[twoside,reset,left=2cm]{geometry}|
%   \end{quote}
%   with |\ExecuteOptions{scale=0.9}| in |geometry.cfg|,
%   then as a result, |landscape| and |left=2cm| remain effective,
%   and |scale=0.9| and |twoside| are ineffective.
% \item[mag] sets magnification value (\cs{mag}) and automatically modifies 
%   \cs{hoffset} and \cs{voffset} according to the magnification.
%   |mag=|\meta{value}. Note that \meta{value} should be an integer value
%   with 1000 as a normal size. For example, |mag=1414| with |a4paper|
%   provides an enlarged print fitting in |a3paper|, which is $1.414$
%   (=$\sqrt{2}$) times larger than |a4paper|. Font enlargement needs extra
%   disk space. \textbf{Note that you should not specify |mag| more than
%   once.} Multiple |mag| specification causes an error.
%   See also |truedimen| option. 
% \item[truedimen] changes all internal explicit dimension values into 
%   \textit{true} dimensions, e.g., |1in| is changed to |1truein|.
%   Typically this option will be used together with |mag| option. Note that
%   this is ineffective against externally specified dimensions. For example,
%   when you set ``\texttt{mag=1440, margin=10pt, truedimen}'', margins are
%   not `true' but magnified. If you want to set exact margins, you should
%   set like ``\texttt{mag=1440, margin=10truept, truedimen}'' instead.
% \item[\New{3}pass] disables all of the geometry options and calculations
%   except |verbose| and |showframe|. It can be used for checking
%   out the page layout of the documentclass, other packages and manual
%   settings without \textsf{geometry}.
% \item[\New{3}showframe] shows visible frames for the text area and page,
%   and the lines for the head and foot on the first page.
% \item[\New{3}compat2] sets all kind of options so that 
%   |\usepackage[compat2]{geometry}| would behave as if one is using
%   the old version (v2.3) with the old default layout:
%   \texttt{[scale=\{0.8,0.9\}, centering, includeheadfoot]},
%   which is here expressed by options available in version 3.
%   Note this option should be set as a first option.
% \end{Options}
%
% \section{Default Settings}
%
% \subsection{Default Layout}\label{sec:default}
%
% Let us recapitulate the default layout here.
% The \textsf{geometry} package has the following default page layout
% for onesided documents:
% \begin{quote}
%   |scale=0.7, marginratio={1:1, 2:3}, ignoreall|
% \end{quote}
% For twoside, the horizontal margin ratio is also set |2:3|,
% \begin{quote}
%   |scale=0.7, marginratio=2:3, ignoreall|.
% \end{quote}
% Of course, you don't need to set them explicitly. |\usepackage{geometry}|
% will internally set the above options.
% Additional options will overwrite the layout dimensions. For example,
% \begin{quote}
% |\usepackage[hmargin=2cm]{geometry}|
% \end{quote}
% will overwrite horizontal dimensions, but use the default for vertical
% layout. Page dimensions specified by the documentclass being used 
% and other direct settings before \textsf{geometry} is loaded are passed
% down to \textsf{geometry}.
%
% Note version 2.3 or earlier had default layout different from the
% version 3. The old default options can be expressed with options 
% available in the current version:
% \begin{quote}
%   |scale={0.8,0.9}, centering, includeheadfoot|.
% \end{quote}
% Adding |compat2| as a first option sets those options so that, for example,
% \begin{quote}
% |\usepackage[compat2, width=10cm]{geometry}|
% \end{quote}
% would behave as if one is using the old version (v2.3).
%
% \subsection{Configuration File}
%
% One can set up a configuration file to make default options. To do this, 
% produce a file |geometry.cfg| containing an \cs{ExecuteOptions} macro,
% for example, 
% \begin{quote}
% |\ExecuteOptions{a4paper,dvips}|
% \end{quote}
% and install it somewhere \TeX{} can find it.
% 
% The options specified in the |geometry.cfg| can be cleared by 
% option |reset|.
%
% \section{Relations Between Options}
% This section shows how complexity is solved when options are over-specified.
%
% \subsection{Order Dependence}\label{sec:order-depend}
%
% The \textsf{geometry} options are basically order-independent, but there
% are some exceptions. For multiple specification of the same option,
% the last setting is adopted. For example,
% \begin{quote}
%   |verbose=true, verbose=false|
% \end{quote}
% obviously results in |verbose=false|.
% If you set
% \begin{quote}
%   |hmargin={3cm,2cm}, left=1cm|
% \end{quote}
% the left(or inner) margin is overwritten by |left=1cm|. As a result, it is
% equivalent to |hmargin={1cm,2cm}|. 
% 
% The |reset| option removes all the geometry options (except |pass|)
% before it. If you set
% \begin{quote}
% |\documentclass[landscape]{article}|\\
% |\usepackage[margin=1cm,twoside]{geometry}|\\
% |\geometry{a5paper, reset, left=2cm}|
% \end{quote}
% then |margin=1cm|, |twoside| and |a5paper| are removed.
% As a result, this case is equivalent to
% \begin{quote}
% |\documentclass[landscape]{article}|\\
% |\usepackage[left=2cm]{geometry}|
% \end{quote}
%
% \subsection{Priority}
%  
% There are several ways to set dimensions of the printable area:
% |scale|, |total|, |text| and |lines|. Basically specification with the more
% concrete dimension has the higher priority:
% \[\begin{array}{c}
%  \textrm{low}\quad\longrightarrow\quad\textrm{high}
%              \quad(\textrm{priority})\\[1em]
% \left\{\begin{array}{l}|hscale|\\|vscale|\\|scale|
%        \end{array}\right\} <
% \left\{\begin{array}{l}|width|\\|height|\\|total|
%        \end{array}\right\} <
% \left\{\begin{array}{l}|textwidth|\\|textheight|
%         \\|text|\end{array}\right\} < |lines|.
% \end{array}\]
% For example, 
% \begin{quote}
%  |\usepackage[hscale=0.8, textwidth=7in, width=18cm]{geometry}|
% \end{quote}
% is the same as |\usepackage[textwidth=7in]{geometry}|. Another example:
% \begin{quote}
%  |\usepackage[lines=30, scale=0.8, text=7in]{geometry}|
% \end{quote}
% results in \texttt{[lines=30, textwidth=7in]}.
%
% Options determining margin size also have priority rule:
% margin ratios versus margin length. For example, if both |marginratio=1:2|
% and |margin=1cm| are set at the same time, |margin=1cm| wins because
% |margin=1cm| is more concrete dimension than ratios. That is why normal
% margin options work well with default margin ratios 
% (|marginratio={1:1, 2:3}| for oneside).
% \[\begin{array}{c}
%  \textrm{low}\quad\longrightarrow\quad\textrm{high}
%              \quad(\textrm{priority})\\[1em]
% \left\{\begin{array}{l}|hmarginratio|\\|vmarginratio|\\|marginratio|
%        \end{array}\right\} <
% \left\{\begin{array}{l}
%            |hmargin|\:\textit{or}\:|left|\:\textrm{\&}\:|right|\\
%            |vmargin|\:\textit{or}\:|top|\:\textrm{\&}\:|bottom|\\
%            |margin|
%        \end{array}\right\}.
% \end{array}\]
%
% \section{Examples}
%
% \begin{itemize}
% \item A onesided page layout with the text area centered in the paper.
% The examples below have the same result because the horizontal margin ratio
% is set |1:1| for oneside by default.
% \begin{itemize}
%   \item |centering|
%   \item |marginratio=1:1|
%   \item |vcentering|
% \end{itemize}
%
% \item A twosided page layout with the inside offset for binding |1cm|.
% \begin{itemize}
%   \item |twoside, bindingoffset=1cm|
% \end{itemize}
% In this case, |textwidth| is shorter than the case without
% |bindingoffset=1cm| by $0.7\times|1cm|$ ($=$|0.7cm|).
%
% \item A layout with the left, right, and top margin |3cm|, |2cm| and
% |2.5in| respectively, with textheight of 40 lines, and with the head and
% foot of the page included in \gpart{total body}.
% The two examples below have the same result.
% \begin{itemize}
%   \item |left=3cm, right=2cm, lines=40, top=2.5in, includeheadfoot|
%   \item |hmargin={3cm,2cm}, tmargin=2.5in, lines=40, includeheadfoot|
% \end{itemize}
%
% \item A layout with the height of \gpart{total body} |10in|, the bottom
%  margin |2cm|, and the default width. The top margin will be calculated
%  automatically. Each solution below results in the same page layout.
% \begin{itemize}
%     \item |vdivide={*, 10in, 2cm}|
%     \item |bmargin=2cm, height=10in|
%     \item |bottom=2cm, textheight=10in| 
% \end{itemize}
% Note that dimensions for \gpart{head} and \gpart{foot} are excluded from
% |height| of \gpart{total body}. An additional |includefoot| makes
% \cs{footskip} included in |totalheight|. Therefore, in the two cases below,
% |textheight| in the former layout is shorter than the latter
% (with 10in exactly) by \cs{footskip}. In other words, 
% |height| = |textheight| + |footskip| when |includefoot=true| in this case.
% \begin{itemize}
%     \item |bmargin=2cm, height=10in, includefoot|
%     \item |bottom=2cm, textheight=10in, includefoot|
% \end{itemize}
%
% \item A layout with \glen{textwidth} and \glen{textheight} 90\% of the
% paper and with \gpart{body} centered.
% Each solution below results in the same page layout.
% \begin{itemize}
%   \item |scale=0.9, centering|
%   \item |text={.9\paperwidth,.9\paperheight}, ratio=1:1|
%   \item |width=.9\paperwidth, vmargin=.1\paperheight, marginratio=1:1|
%   \item |hdivide={*,0.9\paperwidth,*}, vdivide={*,0.9\paperheight,*}| 
%   \item |margin={.1\paperwidth,.1\paperheight}, marginratio=1:1|
% \end{itemize}
% You can add |heightrounded| to avoid an ``underfull vbox warning'' like
% \begin{quote}\small
%  |Underfull \vbox (badness 10000) has occurred while \output is active|.
% \end{quote}
% See Section~\ref{sec:body} for the detail description about |heightrounded|.
%
% \item A layout with the width of marginal notes |3cm| and included in the
% width of \gpart{total body}. The following examples are the same.
% \begin{itemize}
%   \item |marginparwidth=3cm, includemp|
%   \item |marginpar=3cm, igoremp=false|
% \end{itemize}
%
% \item A layout the full scale \gpart{body} of the paper with A5 paper in
% landscape. The following examples are the same.
% \begin{itemize}
%   \item |a5paper, landscape, scale=1.0|
%   \item |landscape=TRUE, paper=a5paper, margin=0pt|
% \end{itemize}
%
% \item  A screen size layout appropriate to presentation with PC and video
%        projector.
% \begin{verbatim}
%   \documentclass{slide}
%   \usepackage[screen,margin=0.8in]{geometry}
%    ...
%   \begin{slide}
%      ...
%   \end{slide}\end{verbatim}
% \item A layout with fonts and spaces both enlarged from A4 to A3.
%  In the case below, the resulted paper size is A3.
% \begin{itemize}
%     \item |a4paper, mag=1414|.
% \end{itemize}
% If you want to have a layout with two times bigger fonts, but without
% changing paper size, you can go 
% \begin{itemize}
%   \item |letterpaper, mag=2000, truedimen|.
% \end{itemize}
%  You can add |dvips| option, that is useful to preview it with proper
%  paper size by |dviout| or |xdvi|.
%
% \item An old style setting with v2.3 or earlier
% \begin{verbatim}
%  \usepackage[a4paper,mag=1200,truedimen,margin=2cm,
%      twosideshift=10pt,
%      headsep=7pt,headheight=14.5pt,
%      marginparwidth=30pt]{geometry}\end{verbatim}
% can be rewritten with options in version 3 without |compat2|:
% \begin{verbatim}
%  \usepackage{calc}
%  \usepackage[a4paper,mag=1200,truedimen,margin=2cm,

% \section{Known Problems}
% \begin{itemize}
%  \item With |pdftex=true|, |mag| $\neq 1000$ and |truedimen|,
%  |paperwidth| and |paperheight| shown in verbose mode are different
%  from the real size of the resulted PDF. The PDF itself is correct anyway.
%  \item With |pdftex=true|, |mag| $\neq 1000$, \textit{no} |truedimen|,
%  and \textsf{hyperref}, \textsf{hyperref} should be loaded
%  by \cs{usepackage} before \textsf{geometry}. 
%  Otherwise the resulted PDF size will become wrong.
%  \item With \textsf{crop} package and |mag| $\neq 1000$,
%  |center| option of \textsf{crop} doesn't work well.
% \end{itemize}
