%\subsection{Introduction}
%\label{sec:intro}
%
% Medical pedigree is a very important tool for clinicians, genetic
% researchers and educators.  As stated
% in~\cite{PedigreeNomenclature95}, ``The construction of an accurate
% family pedigree is a fundamental component of a clinical genetic
% evaluation and of human genetic research.''  Unfortunately, up to
% now most geneticians make the pedigrees manually.  There are several
% programs for doing so (see a list at
% \url{http://www.kumc.edu/gec/prof/genecomp.html#pedigree}), but they
% are rather expensive, lack multilanguage support and the quality of
% typesetting is somewhat lacking.  This package tries to offer a
% \LaTeX-based solution for this problem.  It could be used with a
% companion \path{Perl} program \path{pedigree}~\cite{pedigree-perl},
% which converts databases of patients into a \LaTeX{} file.
%
% Note that there are ways to draw genealogical trees with
% |PSTricks|~\cite{PSTricks93}; see the beautiful ones at
% \url{http://www.tug.org/PSTricks/main.cgi?file=Examples/Genealogy/genealogy}.
% Unfortunately, medical pedigrees are often not \emph{trees}.
% Therefore we do not use tree approach throughout, but provide it as
% an alternative.   Our general approach is based on the use of
% nodes~\cite[Part~VII]{PSTricks93}.  Each person or entity is a node,
% and the lines are in fact |\ncline|s.  This provides a flexibility
% to draw complex pedigrees.
%
% Each node in the system \emph{must} have a name.  To prevent
% confusion with names of individuals, we call such name an \emph{id}.
% As usual in |PSTricks|, it is a sequence of letters and numbers
% starting with a letter.  This rule is very important; a name like 1
% or 1-1 can lead to mysterious PostScript errors.
%
% Our symbols follows the standard~\cite{PedigreeNomenclature95} with
% the exception that we do not implement showing several conditions
% on the same chart.
%
% To use the package, add the line
% \begin{verbatim}
% \usepackage{pst-pdgr}
% \end{verbatim}
% to a \LaTeX{} document or
% \begin{verbatim}
% \input pst-pdgr.tex
% \end{verbatim}
% to a \PlainTeX{} one.  Note that since this is a |PSTricks|
% package, you need to use \path{tex-dvips} path to compile your
% document.  If you need a PDF document, you can use \path{ps2pdf} or
% packages like \path{pst-pdf}, \path{ps4pdf}, \path{pstricks}.
%
% If you are using the package in a \LaTeX{} document, you have an
% added benefit of a local configuration file |pst-pdgr.cfg|.  Such
% file, if exists, will be read. It can be used to override package
% settings (use |\AtEndOfPackage| for this).
%
%
%
%\subsection{Global Settings}
%\label{sec:globals}
% 
% By default the size of each node is |0.5 unit|.  You can change
% the size by setting the value of  |unit| (1\,cm by default)
% with |\psset|
%
%\DescribeMacro{\affectedstyle}
%\DescribeMacro{\affectedbgcolor}
% By default the affected individual is drawn as a black node.  This
% could be changed by setting |\affectedstyle| and
% |\affectedbgcolor|, see Figure~\ref{fig:affectedstyle}.  
%\DescribeMacro{\affectedfgcolor}
% Sometimes we need to write something inside a node representing an
% affected individual.  An example in~\cite{PedigreeNomenclature95}
% changes in this situation the style from filled to hatched, which
% looks inconsistent.  We rather change the color of the foreground,
% as shown on Fig.~\ref{fig:affectedfgcolor}.

%\subsection{Node Drawing Commands}
%\label{sec:node_commands}
%
%
% The node drawing commands are based on the |\pnode| commands from
% |PSTricks|~\cite[Part~VII]{PSTricks93}.  It is the preferred command
% for drawing, for example, a ``marriage node'' (see the examples
% below).  It is useful to remember this when drawing complex
% pedigrees.  
%
%
%\subsubsection{One Person}
%\label{sec:person}
%
% \DescribeMacro{\pstPerson} The main command in the package is
% |\pstPerson|.  It draws one person, which is a |PSTricks| node.  It
% has the following structure: |\pstPerson|\oarg{options}\marg{id}.
% The parameter \meta{id} is the name of the node.  It can be used to
% make connections to the node (see below).
%
% There are many options to this command.  As other |PSTricks|
% options, the also can be set globally through |\psset| command.
%
% 
% \DescribeOptions{sex,condition,deceased,proband,adopted,evaluated}
% The first group of options describes the state of the person:  sex,
% condition with respect to the decease, whether the person is
% deceased, is a proband, was adopted and was evaluated.  These
% options are listed in Table~\ref{tab:person_state_opts}.  Some 
% options of this group can take only two values: |true| or |false|.
% For simplicity the clause |=true| can be omitted, so the clauses
% |adopted=true| and |adopted| are equivalent.  Two options: |sex| and
% |condition| can take several values each (geneticians consider three
% possibilities for sex: |male|, |female| and |unknown|).  Again for
% simplicity the clauses |sex=| and |condition=| can be omitted, so
% the invocations |sex=male| and |male| are equivalent, as well as
% |condition=asymptomatic| and |asymptomatic|.
%
% \DescribeOptions{insidetext,abovetext,belowtext,lefttext,righttext}
% The second group of options (Table~\ref{tab:person_text_opts}) is
% used to putting text comments inside the symbol, above it, below it
% or to the right or left to it.  The text will be typeset in a
% |PSTricks| LR-box~\cite{PSTricks93}; additional control over the
% text position can be achieved by using |\parbox| or \PlainTeX{}
% boxes. 
%
% \DescribeOptions{abovetextrp,belowtextrp,lefttextrp,righttextrp} 
% The third group of options (Table~\ref{tab:person_text_rp_opts}) is
% used to set the text position with respect to the node.  They set
% the reference point of the text.  They correspond to the usual
% notation: |r| being right, |l| being left, |t| being top, |b| being
% bottom and |B| being baseline.  The setting |={}| makes the
% reference point to be the center of the box.  Note that to prevent
% the text above and below the symbol to clash with the descent lines,
% the spaces of |2\pslinewidth| are added to the right and to the left
% of the symbol.
%
% Examples of usage of this command are shown in
% Table~\ref{tab:pstPerson}.

%\subsubsection{Pregnancy Not Carried To Term}
%\label{sec:abortion}
% 
% \DescribeMacro{\pstAbortion} 
% The command |\pstAbortion| is used to draw a pregnancy not carried
% to term: spontaneous abortions or terminated pregnancies.  The
% format of it the same as for the command |\pstPerson| (see
% Section~\ref{sec:person}): |\pstAbortion|\oarg{options}\marg{id}.
% However, many of options listed in Table~\ref{tab:person_state_opts} are
% silently ignored.  The only options meaningful for these nodes are
% |sex| and |condition| (only |normal| and |affected| values are
% possible).  All options listed in Table~\ref{tab:person_text_opts}
% and \ref{tab:person_text_rp_opts} are valid and have the same
% meaning as in Section~\ref{sec:person}. 
%
% \DescribeOption{sab} 
% The command has also an option |sab| with the values |true| or
% |false|.  If it is |true|, the pregnancy is a spontaneous abortion.
% Otherwise it is terminated.  Examples of usage of this command are
% shown in Table~\ref{tab:abortions}.

% 
% The symbols for childlessness and infertility are listed under

% make the placing the symbols on the chart more flexible, we assign
% nodes to them.  
%
% \DescribeMacro{\pstChildless} 
% The command for drawing these symbols
% has the same structure as the other node drawing commands:

% While all options listed in Table~\ref{tab:pstPerson} are valid, the
% only meaningful one is |belowtext|.  Note that the option
% |belowtextrp| is silently ignored:  the text is always centered
% below the infertility symbol.  
%
% \DescribeOption{infertile}
% There is one additional option
% |infertile|, which can have values |true| of |false|.  If it is
% |false|, the person (or relationship) is childless by choice (or by
% an unknown reason).  The clause |=true| can be omitted.

%\subsubsection{Relationship}
%\label{sec:relationship}
%
%\DescribeMacro{\pstRelationship}
% Relationships are marriages or other unions.  The main command for
% drawing relationships is 
% |\pstRelationship|\oarg{options}\marg{nodeA}\marg{nodeB}.  It draws
% a relationship line between \marg{nodeA} and \marg{nodeB}.  Normal
% |PSTricks| options like |linestyle=dashed| can be used with the
% expected effect.
%
% \DescribeOptions{broken,consanguinic,descentnode,brokenpos,descentnodepos,rellinecmd}
% There are also several options specific for this command, listed in
% Table~\ref{tab:relationship_opts}. The options |broken| and
% |consanguinic| are self-explanatory.  The option |descentnode| is
% used, if we want the descent lines to start at a node on the
% relationship line.  The name of this descent node must satisfy the
% usual criteria for the node (see Section~\ref{sec:intro}).  The
% options |brokenpos| and |descentnodepos| determine, where on the
% relationship line the corresponding objects are placed.  The option
% |rellinecmd| allows to change the default straight line for the
% relationship to something else, like |ncbar|, |ncangle|, etc.
% Examples of this command use are shown in
% Table~\ref{tab:pstRelationship}

%\subsubsection{Descent}
%\label{sec:pstDescent}
% 
% The paper~\cite{PedigreeNomenclature95} distinguishes between
% descent line and sibs line.  We, however, will call all segments of
% the line, joining a parent (or a descent node) and a child the
% descent line.  \DescribeMacro{\pstDescent} The main command for
% showing parent-child relations is
% |\pstDescent|\oarg{options}\marg{Parent}\marg{Child}.  It has no
% special options, but the usual |\PSTricks| options for lines are
% valid.  The most important option is |armB|: the length of the
% segment between the parent node and the sib line.  Note that to make
% the sib line straight the actual direction of the |\ncangle| used by
% |\pstRelationship| internally is \emph{reversed}: from \marg{Child}
% to \marg{Parent}. Examples of this command are shown in
% Table~\ref{tab:pstDescent}.  Note the option |linestyle=dashed| used
% to show social parentage in the first example.

%\label{sec:pstTwins}
%
%
%
% \DescribeMacro{\pstTwins} A special care is needed when we talk
% about twins.  First, the user must define a \emph{twin node}: the
% node which is used as a nexus for twin lines.  Then the following
% command draws all the necessary
% lines: \\
% |\pstTwins|\oarg{options}\marg{Parent}\marg{TwinNode}\marg{LeftTwin}\marg{RightTwin}.
%
% \DescribeOptions{monozygotic,qzygotic,mzlinepos,addtwins}
% The options for this command are listed in
% Table~\ref{tab:twin_opts}.  The option |monozygotic| allows to show
% that the twins are monozygotic.  The actual position of the
% horizontal line is determined by the option |mzlinepos|.  If it is
% unknown, whether the twins are monozygotic or not, |qzygotic|
% options draws a question mark, as recommended
% by~\cite{PedigreeNomenclature95}.  Note that |mzlinepos| in this
% situation helps to position the question mark properly.  The option
% |addtwin| allows to draw pedigrees with more than two twins.  It can
% be repeated several times if necessary.  Examples of the usage of
% this command are shown in Table~\ref{tab:pstTwins}.

%\subsection{Making Trees}
%\label{sec:trees}
%
% As discussed above (Section~\ref{sec:intro}), the medical pedigrees
% are not necessary trees.  Even if they are, they are usually not
% simple layered trees.  Nevertheless sometimes pedigree can be
% represented as a layered tree.  For such cases we provide tree
% drawing commands.  See the discussion in~\cite{pedigree-perl} for
% more details.
%
% \DescribeMacro{\TpstPerson}
% \DescribeMacro{\TpstAbortion}
% \DescribeMacro{\TpstChildless}
% The macros |\TpstPerson|, |\TpstAbortion| and |\TpstChildless| have
% the same options and arguments as their ``normal'' counterparts.  You
% probably need to use command like
% \begin{verbatim}
% \def\psedge{\pstDescent}
% \psset{armB=1}
% \end{verbatim}
% in your code.  An example of us of such commands is shown on
% Figure~\ref{fig:example_tree}.  Note that the resulting figure is
% \emph{not} a tree!  The corresponding code is shown on
% Figure~\ref{fig:example_tree_code}.

%\section{Implementation}
%\label{sec:implementation}
%
%
%
%\subsection{Identification and Setting Up}
%\label{sec:identification}
%
%
%Traditionally |PSTricks| works in two regimes:  the \LaTeX one and
%the plain one.  Probably it is a good idea to keep this
%tradition. Therefore we will use a \TeX{} file \path{pst-pdgr.tex}
%and a \LaTeX file \path{pst-pdgr.sty}.  They have different means of
%preserving from loading twice and identification.  
%
% \begin{macro}{\PSTPedigreeLoaded}
% A \TeX{} guard |\PSTPedigreeLoaded| prevents the double loading
% of the file:
%    \begin{macrocode}
%<*tex>
\csname PSTPedigreeLoaded\endcsname
\let\PSTPedigreeLoaded\endinput
%</tex>
%    \end{macrocode}
% \end{macro}
%
%Now we can start real identification.  Note the difference between
%the ways a \LaTeX{} style, a \LaTeX{} configuration file and a \TeX{}
%file announce itself
%    \begin{macrocode}
%<latex>\NeedsTeXFormat{LaTeX2e}
%<latex>\ProvidesPackage{pst-pdgr}
%<cfg>\ProvidesFile{pst-pdgr.cfg}
%<tex>\message{
[2006/04/18 v0.2a Medical Pedigree with PSTricks]
%<tex>}
%    \end{macrocode}
%
% The \LaTeX{} style is in fact just a wrapper: it calls the
% configuration file, and then the \TeX file, which does the real
% work:
%    \begin{macrocode}
%<*latex>
\InputIfFileExists{pst-pdgr.cfg}{%
  \typeout{Loading configuration file pst-pdgr.cfg}}{%
  \typeout{Configuration file pst-pdgr.cfg is not found}}
\input{pst-pdgr.tex}
%</latex>
%    \end{macrocode}
%
% Now we are dealing (almost) exclusively with \TeX.
%    \begin{macrocode}
%<*tex>
%    \end{macrocode}
%
% Check the packages we use  are loaded:
%    \begin{macrocode}
\ifx\PSTricksLoaded\endinput\else\input pstricks.tex\fi
\ifx\PSTnodesLoaded\endinput\else\input pst-node.tex\fi
\ifx\PSTreeLoaded\endinput\else\input pst-tree.tex\fi
\ifx\PSTXKeyLoaded\endinput\else\input pst-xkey.tex\fi
%    \end{macrocode}
%
% We set up that |@| symbol:
%    \begin{macrocode}
\catcode`\@=11\relax
%    \end{macrocode}
% and set up keys for our package
%    \begin{macrocode}
\pst@addfams{pst-pdgr}
%    \end{macrocode}
%
%\subsection{Global Parameters}
%\label{sec:impl_globals}
%
% These macros define the way affected individuals are drawn
% \begin{macro}{\affectedbgcolor}
% The background color:

%    \end{macrocode}
% \end{macro}
% \begin{macro}{\affectedfgcolor}
% The foreground color for the text:
%    \begin{macrocode}
\def\affectedfgcolor{white}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\affectedstyle}
%   And the style:
%    \begin{macrocode}
\def\affectedstyle{fillstyle=solid, fillcolor=\affectedbgcolor}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\pst@pdgr@intxtcolor}
% Normally the color of the inside text for normal persons is the
% current color:
%    \begin{macrocode}
