%\section{Introduction}
% The \textsf{philokalia} package has been designed to ease the use of the Philokalia-Regular (henceforward
% it will specified simply as the font)
% OpenType font with \XeLaTeX. The package provides two options: \texttt{global} and \texttt{local}.
% When the package is used with the \texttt{global} option the font is made the main font of the entire 
% document. Also, this option provides support to typeset titling capitals. 
% When the package is used with the \texttt{local} option, which is the default option,
% it provides the commands \verb=\textphlk= and \verb=\phkl= to enable typesetting of short passages. 
% The first command takes one argument which is typeset using the font. The second command makes the font 
% the main font of the current (local) scope. The complete package provides the 
% following \XeLaTeX\ files:
%\begin{center}
% \begin{tabular}{ll}
%   driver     &amp; produce the documentation \\
%   philokalia &amp; the package itself \\
%   TUpkl     &amp; The Philokalia font shapes\\
% \end{tabular}
% \end{center}
% 
% \section{About The Font}
%  
% The font started as a project to digitize the typeface that was
% used to typeset the Philokalia books. For information regarding these books, the reader
% should visit either the following URL:
%\begin{center}
% \verb=http://orthodoxwiki.org/Philokalia=
%\end{center}
% or enter the word {\em philokalia} in the Amazon.com search box, for information about various
% editions of the books. The project was carried out by 
% Apostolos Syropoulos and Ioannis Gamvets. Initially, the project was part
% of Ioannis Gamvetas's diploma thesis, but the resulting OpenType font is not part of this
% thesis work and it was developed by this author. The goal of the original thesis work was to develop Type~1 
% fonts and tools to typeset portions of the Philokalia books with Omega. Since, the original thesis work 
% has not been completed yet (!), the idea of releasing an OpenType font emerged quite naturally.
% The font contains only Greek letters and it can be used to typeset any Greek text. However, since the 
% shapes of the letters are not that obvious, here is a ``translation''-table:
% \begin{center}
% \begin{tabular}{cccccccccc}
% \textphlk{ﾎｱ} &amp; \texttt{ﾎｱ} &amp; \textphlk{ﾎｲ} &amp; \texttt{ﾎｲ} &amp; \textphlk{ﾎｳ} &amp; \texttt{ﾎｳ} &amp;

% \textphlk{ﾏ�} &amp; \texttt{ﾏ�} &amp; \textphlk{ﾏ厭 &amp; \texttt{ﾏ厭 
% \end{tabular}
% \end{center}
% One interesting feature of this font is that accents are placed {\em after} capital
% letters (see the sample below). Another interesting feature of the font is the great number of 
% ligatures it includes. In fact, it includes more than 40 {\em historical} ligatures plus two 
% {\em contextual} ligatures. When typing \texttt{ﾎｺﾎｹ} and these letters are not part of a word, then
% one gets the contextual ligature \textphlk{ﾎｺﾎｹ}, which is the Greek ampersand. The same ligature can be
% obtained if we substitute {\em iota} with {\em iota with varia}. The table below shows all the historical
% ligatures included in the font:

%  
% \end{tabular}
% \end{center}
% Notice that in order to get the symbols \textphlk{ﾎ�-} and \textphlk{ﾎ�1}
% one has to type a tonos and then a
% hyphen or the digit one, respectively. The symbols \textphlk{ﾎ�-} and  \textphlk{ﾎ�1}
% have been used by the ancient Greek mathematician Diophantus to denote the subtraction 
% operator\footnote{Diophantus did not explicitly specified negative numbers in his writings, although
% he was aware of them.}  and
% an unknown quantity (similar to the $x$ we use today in simple equations like $x+x^2=3$). Also, the
% symbols \textphlk{1ﾎ慚ｿ} and \textphlk{1ﾎｼﾎｿ} have been used by Diophantus to denote the unit (i.e., the
% number one). These symbol were not in the original Philokalia font, but they have been
% included here for reasons of completeness. The followin commands are provided for people who only
% want to typeset these symbols: \verb=\dsubop=, \verb=\dUnit=, \verb=\dunit=, and \verb=\dunknown=.  
%
%  The font includes titling capitals that are accessible through the titling OpenType feature,
% which, however, is implicitly available. In particular, the command \verb|\textinit|, which has two 
% arguments, the first being the first letter of a word and the second being the rest of the word,
% can be used to typeset a drop capital. The following short passage from Aristotle's treatise 
% {\em The Poetics} was typeset with the font so as to demonstrate the various features of it.

%  ﾎｱ眇積�ｿ��\ldots}
% \end{center} 
% Notice that here we enable the \texttt{ancientgreek} hyphenation patterns to allows \XeTeX\ to correctly
% hyphenate the text.
%
% \section{The package \textsf{philokalia}}
%
% First of all, we have to load a number of packages that are necessary for the correct use of the font.
% In addition, we use the \textsf{lettrine} package to typeset the titling capitals. 
%    \begin{macrocode}
%&lt;*philokalia&gt;
\RequirePackage{xltxtra}
\RequirePackage{lettrine}
\newsavebox{\Pb@x}
%    \end{macrocode}
% Unfortunately, we cannot use the \textsf{lettrine} package as it stands. We need to sligthly modify
% two macros. In particular, the macro \verb=\Lettrine@height=, which computes the height of the 
% titling capital, has to compute the height of the letter \texttt{x} of a font in order to 
% carry out its computation. Since the font does not include this character, we had to modify the
% code so as to compﾎｽute the height of the letter \texttt{ﾎｱ} instead. Similarly, we had to modify the macro 
% \verb=\LettrineFont= because it was designed with the assumption that the main font of the document has 
% the \texttt{X} character, which, again, is not valid for our case.    
%    \begin{macrocode}
\def\Lettrine@height{%
   \@tempdima=\baselineskip
   \setlength{\L@height}{\theL@lines\@tempdima}%
   \ifnum\theL@lines&gt;1
     \addtolength{\L@height}{-\@tempdima}%
   \fi
   \sbox{\L@tbox}{\LettrineTextFont "03B1}%%%% Modified here
   \addtolength{\L@height}{\ht\L@tbox}%
   \addtolength{\L@height}{\L@oversize\L@height}}
\renewcommand*{\LettrineFont}{%
   \Lettrine@height
   \sbox{\L@tbox}{\LettrineFontHook\fontsize{\L@height}{\L@height}%
                  \selectfont "0391}%%%% Modified here
   \@tempcntb=\ht\L@tbox
   \@tempcnta=\L@height
   \multiply\@tempcnta by 100
   \divide\@tempcntb by 100
   \divide\@tempcnta by \@tempcntb
   \advance\@tempcnta by -9999
   \ifnum\@tempcnta&gt;0
     \def\@tempa{1.\the\@tempcnta}%
   \else
     \def\@tempa{1}%
   \fi
   \LettrineFontHook
   \fontsize{\@tempa\L@height}{\@tempa\L@height}%
   \selectfont
}
%    \end{macrocode}  
% Now, we have to define the two options: global and local (the default one). In the first case, we 
% define the command \verb|\textinit| that is used to typeset drop capitals from the titling
% capitals included in the font. By default, the \texttt{titl} feature of the font is not enabled
% as this would mean that all paragraphs would start with these really huge titling capitals.
% Also, the font is made the default font for the entire document. Notice that we use a box variable
% to store the letter that will appear as a drop capital. This is necessary in order to have in 
% the box the titling capital and not the ordinary capital letter, or else the \verb|\lettrine|
% command will fail to correctly compute the height and width of the letter.
%    \begin{macrocode}
\DeclareOption{global}{%
   \renewcommand{\rmdefault}{plk}%
   \DeclareFontFamily{TU}{plktitl}{}%
   \DeclareFontShape{TU}{plktitl}{m}{n}%
    {&lt;-&gt; "[Philokalia-Regular]/ICU:script=grek,+titl"}{}%
   \newcommand{\textinit}[2]{%
       \savebox{\Pb@x}{\usefont{TU}{plktitl}{m}{n} #1}%
       \lettrine[lines=3]{\usebox{\Pb@x}}{#2}}%
}
%    \end{macrocode}
% When the package is used with the default option, it provides two commands to typeset short
% passages of text. As is evident from the code that follows, the first macro is actually a
% definition and the second a command that can be used to typeset its argument with the font. Users
% should use the definition with care.
%    \begin{macrocode}
\DeclareOption{local}{%
   \def\phkl{\fontfamily{plk}\selectfont}%
   \newcommand{\textphlk}[1]{{\phkl #1}}%
}
\ExecuteOptions{local}
\ProcessOptions
%    \end{macrocode}
% The following commands are glyph access commands for the archaic mathematical symbols included in
% the font. They produce the symbols \dsubop, \dUnit, \dunit, and \dunknown, respectively.
%    \begin{macrocode}
\def\dsubop{{\fontfamily{plk}\selectfont\char"018B}}
\def\dUnit{{\fontfamily{plk}\selectfont\char"018C}}
\def\dunit{{\fontfamily{plk}\selectfont\char"018D}}
\def\dunknown{{\fontfamily{plk}\selectfont\char"018E}}
%&lt;/philokalia&gt;
%    \end{macrocode}
%
% \section{The Font Definition File}
% Since there is only one font shape, there is not much work to do: we just need to specify 
% the available font properties. We use the standard font encoding defined by package
% \textsf{fontspec}. In this version we use \texttt{TU} font encoding instead of \texttt{EU1}, which was
% predefined by the same package. 
%    \begin{macrocode}
%&lt;*TUplk&gt;
\DeclareFontFamily{TU}{plk}{}
\DeclareFontShape{TU}{plk}{m}{n}%
     {&lt;-&gt; "[Philokalia-Regular]/ICU:script=grek,+hlig,+clig:mapping=tex-text"}{
}
%    \end{macrocode}
% And then we define the various substitutions:
%    \begin{macrocode}
\DeclareFontShape{TU}{plk}{m}{sl}{&lt;-&gt; ssub * plk/m/n}{}
\DeclareFontShape{TU}{plk}{m}{it}{&lt;-&gt; ssub * plk/m/sl}{}
