% \section{Introduction}
% As the abstract stated this package exists to provide a simple user
% interface to the character protruding feature of
% pdf\TeX\footnote{You'll find pdf\TeX{} on
% |CTAN:/sytems/pdftex|.}. This is a special way to do a margin
% kerning. By that it is possible to achieve a visual more ``smooth''
% margin. When not doing a margin kerning, the margins seems to be flattered a bit, especially at
% hyphens and punctuation. Character Protruding is a simple but nevertheless effective
% way to achieve a margin kerning.  For more information
% about margin kerning and especially character protruding see the
% thesis of H\`{a}n Th\'{\^{e}}
% Th\`{a}nh~\cite{hanthethanh:thesis}\footnote{It could be found on the
% web, but I don't remember where I got it.}.
%
% \subsection{A bit of History}
% Why did I write this package, so you can use it now? Well, it all
% started with my diploma thesis. I used \LaTeXe{} on a regular basis
% before that, but here I still had to increase my knowledge, esp. in
% typography. So I read somewhere in a book something about margin
% kerning (some book of Jan Tschichold). So I wanted to test, how
% it would look like.
%
% But my first questions in |de.comp.text.tex| where a bit
% unsuccessful. The only answers where, that it could be achieved with
% \TeX{}, but that it is not without problem. As an example the
% \LaTeX{}-Companion was mentioned, at least the German
% edition\cite{begleiter} was put with a kind of hanging
% punctuation. But in the preface Frank Mittelbach stated, that there
% doesn't exist a ready to use package for \LaTeXe{} and one would have
% to wait for \LaTeX3 very likely. And as you can easily see, only the
% hyphens and the punctuation signs were protruded. That was the
% situation of November 1994.
%
% But the situation seemed to be the same in 2000. I found
% \emph{nothing} really usable with \LaTeXe{} to put a longer text with
% (longer than some paragraphs). Then someone pointed out,
% that character protruding is a feature provided by the new
% pdf\TeX. At first I was a bit sceptical because I didn't want to
% switch, needing the possibility to use |EPS| input (I heavily
% used |psfrag|). But soon it was pointed out, that pdf\TeX{} supports
% |DVI| output and that in this mode pdf\TeX{} has no limitations
% compared to \LaTeX. Shortly after getting this information I found
% |protcode.tex| provided by H\`{a}n Th\'{\^{e}} Th\`{a}nh.
%
% That I transfered to a packaged for my own use and as some people
% showed interests on |de.comp.text.tex| I posted it
% there.\footnote{The first version was named |optrandausgleich.sty|
% and a second |pdftexfeats.sty|.} But it was never what I expected
% by a package to submit it to |CTAN|. It lacked documentation and
% the support of setting the character protruding depending on the
% used font.
%
% First I wanted to write a package adjusting some of the additional
% features of pdf\TeX{} (for instance the security features). But in
% discussions with Heiko Oberdiek he convinced me, that it is better
% to have some smaller packages instead of putting all into
% one. Additionally the resulting |pdfcprot| package grew more complex
% than expected at first. So the code is complex enough for me to
% maintain and Heiko does a really good job with |pdfsec.sty| (he
% supports more than pdf\TeX).
%
% \subsection{Provided Features}
% This package provides a very simple interface to support a font
% dependent selection of the adjustment of the character
% protrusion. You can easily choose, which fonts will be protruded
% depending on high level \LaTeXe{} font selection not knowing which
% font actually will be used. Further on it is very simple to adjust
% the character protrusion for fonts not ``supported''  directly (only
% for Palatino character protrusion adjustment set (|CPA|) is provided and
% that will be used for \emph{all} fonts, not having a special |CPA|).
%
% Further on an option to switch the pdf\TeX{} output to |DVI| and a
% command testing, whether you use |PDF| output or not are
% provided.\footnote{That was originally from \KOMAScript.}
%
% \section{Using this package.}
%
% First you have to invoke it with a |\usepackage{pdfcprot}| in
% the preamble of your document. Of course you have to use pdf\TeX{} to
% get any effect, but the package just gives a warning if you don't.
%
% \subsection{Requirements}
%
% This package need just two packages, which should be part of every
% \LaTeXe{} distribution not too old: |keyval.sty| (part of the
% |graphicx| bundle) and |ifthen.sty|). If they're not installed, get
% them from |CTAN|.
%
% \subsection{Character Protruding}
%
% For using the character protruding two user interfaces are
% implemented. If you just want to activate it for the most common
% used fonts, not thinking much about internals just use the
% \emph{simple} interface.
%
% When you don't like the preselection of the fonts being adjusted for
% character protruding, you may want to use the \emph{advanced} user
% interface. As the usage of many fonts for character protruding is
% very memory consuming, there may be some cases you want to choose
% non-ambiguous the fonts getting character protruding sparing any useless
% font.
%
% \subsubsection{The \emph{Simple} User Interface}
%
% For the ``normal'' \LaTeXe{} user, who just wants to activate the
% character protruding one option is provided. 
% \DescribeOption{activate}{\Option{activate [=none, normal]}}If you
% just want to activate character
% protruding for the most used fonts just say |activate| or
% |activate=normal| (these two forms are synonyms). For which fonts the
% character protrusion will be enabled is shown in
% table~\ref{tab:activate}. 
%
% By default character protruding won't be enabled, but if you want the
% options to reflect it say |activate=none|. 
%
% \begin{table}
% \centering%
% \begin{tabular}{l l l}\hline\hline
% family & series & shape\\\hline
% |\rmfamily| & |\mdseries| & |\upshape|\\
% & & |\itshape|\\
% & |\bfseries| & |\upshape|\\
% |\sffamily| & |\mdseries| & |\upshape|\\
% & & |\itshape| \\
% & & |\slshape| \\
% |\sffamily| & |\bfseries| & |\upshape|\\
% \hline\hline
% \end{tabular}\\[2mm]
% sizes for all fonts: |\footnotesize|, |\small|,
% |\normalsize| and |\large|
% \caption{Fonts for which character protrusion will be enabled
% using the package option
% \texttt{avtivate=normal}.}\label{tab:activate}
% \end{table}
%
% \emph{Some comments:} You may wonder why character protruding is
% activated for so many font types and not just for |\rmfamily||\mdseries||\upshape|
% and maybe |\sffamily| |\mdseries||\upshape| using |activate| or
% |activate=normal| as package option. That is done
% because I don't want to bother the ``normal'' \LaTeXe-user with more
% than passing the one option to the package but I still want to
% catch the fonts, most likely to be used in cases ``needing''
% character protrusion (this means justified text). As this may appear
% not only for the text type (but e.g. also for captions), though the
% two fonts mentioned above are not sufficient.
%
% \subsubsection{The \emph{Advanced} User Interface}
%
% In some cases it may be favourable to have a bit more control over the font
% selection for the character protruding. With the commands described
% in this section a very fine selection is possible.
%
% The first command to be mentioned has a very simple syntax. It
% allows the user to select a specific font encoding to be set up. It
% will perform the same setup for the given fontencodings as the
% |activate=normal| package option does without selection of font
% encoding. As for now |pdfcprot| has no opportunity to automagically
% detect the loaded font encodings, it will be necessary for setting
% up character protuding in cases where more than one font encodings
% are used.

% \end{quote}
%
% will set up character protruding for both |T1| and
% |T2A| font encodings. This might be nessessary for example, if you
% want to use both German  and Russian text in one document.
% \end{description}
%
% The second command to be mentioned has a high level syntax. For that
% it's possible to choose the font by high level \LaTeXe{} font
% selection commands but only \emph{one} font at a time is
% selectable. To setup the character protruding for more than one
% font, this command has to be called more than once.

% \begin{tabularx}{\linewidth}{@{}p{\myT} X@{}}

% \end{tabularx}
% \begin{tabularx}{\linewidth}{@{}p{\myT} X@{}}
% |size| & This tag is to select the wanted font sizes. Valid values
% are also the \LaTeXe{} high level font size selection commands
% without trailing backslash, that are: |Huge|, |huge|, |LARGE|,
% |Large|, |large|, |normalsize|, |small|, |footnotesize|,
% |scriptsize|, and |tiny|. \emph{This tag is mandatory.}\\
% \end{tabularx}
% \begin{tabularx}{\linewidth}{@{}p{\myT} X@{}}
% |textcomp| & This is a boolean switch for choosing whether to
% activate character protruding for TS1 encoded fonts also or
% not. Values are |true| (|on|, |yes|, |1|), or |false| (|off|, |no|,
% |0|). \emph{This tag is optional. If this tag is not specified it
% defaults to \emph{|false|}.}\\
% \end{tabularx}
%
% \paragraph{The low level font selection.} The ``normal'' parameters
% for font selection are the high level \LaTeXe{} font selection
% commands without trailing backslash. Using any option other than
% that for the tags |family|, |series|, and |shape|, a low level font
% selection command will be suggested. By that it is possible
% to setup the character protruding for a font with a user defined font
% selection command but without struggling with internal commands of

%
% A low level selection of the font size is not possible with

% high level \LaTeXe{} ones, the usage of internal |pdfcprot| commands
% is needed.
%
% To setup more than two or three fonts with the command above
% described would be a bit long-winded. So there's another command
% provided with which it is possible to select more than one font at a
% time (with some limitations).

% \item[Example 1:] For |\rmfamily||\mdseries| the character
% protruding is to be adjusted for |\upshape| and |\itshape| for the
% sizes |\large|, |\normalsize| and |\footnotesize|. Further for the
% font |\rmfamily||\bfseries||\upshape| with the same font sizes, but
% in T2A encoding,
% character protruding is wanted. To achieve that, one would have to call:
% 
% \begin{quote}
% |\usepackage[activate=none]{pdfcprot}|\\
% |\setupcharprotrudingnumeral{family=2,series=2,shape=12,size=52}|\\
% |\setupcharprotrudingnumeral{encoding=T2A,family=2,series=1,shape=8,size=52}|\\
% |\activatecharprotruding|
% \end{quote}
%
% Explanation: |family| and |series| are directly readable from
% table~\ref{tab:scpnum}, as is |shape| for the second call of
% |\setupcharprotrudingnumeral|. To get the value of |shape| for the
% first command, the values for |shape=upshape| and |shape=itshape| (8
% and 4) must be added. Similar it's for |size|, one has to add the values
% for |size=footnotesize| (4), |size=normalsize| (16), and
% |size=large| (32).
% \end{description}
%
% The setup of character protruding using
% |\setupcharprotrudingnumeral| is just possible for fonts accessed by
% high level \LaTeXe{} font selection commands.
%
% \paragraph{Remarks.} Both commands to select the fonts for which
% character protrusion will be adjusted are \emph{only} usable in the preamble
% of the document.
%
% The attentive reader may have noticed another command needed to
% activate the character protrusion when calling the package with the
% option |activate=none|. That is due to the fact, that the
% |\setupcharprotruding| commands just create a command to call at the
% start of the document to adjust the amount of the character
% protruding for a special font (on a character basis), but does not
% activate the using of character protruding itself.
% \DescribeMacro{\activatecharprotruding}{\Macro{activatecharprotruding}\OParameter{\emph{activate}}}Valid 
% values for \texttt{\emph{activate}} are |true| (|yes|, |on|, |1|),
% false (|no|, |off|, |0|), or |compatible| (|compatibility|). Calling
% |\activatecharprotruding| without any parameter means |true|. With
% |true| and |false| the character protruding is switched on and off
% respectively. Why the parameter |compatible|? As the character
% protrusion moves some character into the margins, the word spaces on a
% line may change. When using |activate=true|, |pdflatex| will take this
% additional space into account and by that the line breaks may
% change compared to the use of ``normal'' |latex|. If the line breaks
% are wanted as got by using |latex| but with a active character
% protruding, you'll have to call |\activatecharprotruding| with the
% parameter |compatible|.
%
% The activation of the character protruding is group specific. So it
% is possible to activate and deactivate the character protrusion for
% some parts of a text (but not the \emph{amount} of the character
% protrusion of a special font).
%
% The package output is very informative when looking at the |log| file,
% but the output to |stdout| is normally not. To change that, there's
% one option
% \DescribeOption{quiet}{\Option{quiet=\emph{qt}}} Possible values for
% this parameter are the booleans used in this package (|true|, |on|,
% |yes|, |1|, |false|, |off|, |no|, and |0|). When saying |quiet=no|
% many of the package info will be warnings instead. That is a good
% method to see, which font character protrusion adjustment actually
% will be used (and for which font).
%
% \subsection{The Character Protruding Adjustment -- Creating and
% Using a New One for a Specific Font}
%
% \emph{This section is a bit technical and a study of the source code
% may be very helpful (and is recommended).}\\
%
% To understand what the purpose of this section is, a description of
% the strategy of the package is needed. So what does the package do?
% The command |\setupcharprotruding| and its numerical equivalent will
% create a command with the fitting font selection commands and a
% command |\CPROT@setprotcodes@font|. The whole command will be called at the
% start of the document. Then the font selection takes place and
% |\CPROT@setprotcodes@font| looks, what font was requested
% actually.\footnote{The commands used to determine which font is loaded
% (\texttt{\string\f@family}, \texttt{\string\f@series},
% \texttt{\string\f@shape}, \texttt{\string\f@encoding}) return the
% font requested to \TeX{} \emph{not} the font actually used, so it
% seems. That means for instance if you request a bold Palatino font
% with \texttt{\string\bfseries}, \TeX{} will try to load \texttt{ppl/bx/n} but will only
% find and use \texttt{ppl/b/n} (at least on my system). So as series the
% actual font will be \texttt{b} and not \texttt{bx} which will be reported by the
% use of \texttt{\string\f@series}. Though one could think it would be needed to
% adjust the character protruding in a \texttt{CPA} for
% \texttt{pplbn}, it will be looked for \texttt{pplbxn} instead.} Then it
% looks if a command named |\f@family| |\f@series||\f@shape\f@encoding| is
% defined (the concatenate values of the commands). If it is, this command will be
% used to setup the character protruding, if not |pdfcrpot| will try
% to load a file named |fontname.cpa| containing this command. If that
% fails as well, a fallback font will be used (by default it will be
% |pplmn| with the appropriate font encoding).
%
% To define the command to set up the character protruding, an
% external file was chosen to get an easier maintenance. Defining it
% in the package would enlarge the package noticeably and the package
% would soon become overcrowded.
%
% So if a special character protruding setting for a
% font is wanted, copy the file |pplmnT1.cpa| (for T1 encoding) to the
% required fontname|.cpa| and change the definition of the command
% accordingly.
%
% \begin{description}
% \item[Example: ] A special character protruding setup for the bold version of Palatino in
% T1 encoding is wanted. As the \LaTeXe{} command
% |\bfseries| selects an bold expanded version (|bx|), the font name would be |pplbxnT1.cpa| and
% the command to define |\pplbxnT1|. That means to copy |pplmnT1.cpa|
% to |pplbxnT1.cpa| and change the definition of |\csname pplmnT1\endcsname|
% to |\csname pplbxnT1\endcsname| and further on to adjust the wanted
% |\rpcode| and |\lpcode| values.
% \end{description}
%
% For the meaning of the commands and values in the |CPA| see the documentation of the code
% below and H\`{a}n Th\'{\^{e}} Th\`{a}nh's
% thesis~\cite{hanthethanh:thesis}. There he writes:
% \begin{quote}
% ``\dots A set of common character protruding factors gave quite reasonable
% results in most cases. Non-typical type faces may require further
% adjustments, which can be done easily.''
% \end{quote}
% So for the most fonts the default values may be acceptable, even
% though they are adjusted for Palatino. By using the |CPA| files and
% defining an extra command per font it is very easy to add setups
% for ``non-typical'' type faces without bothering a ``normal''
% \LaTeXe{} user of choosing the right setup because it gets
% automatically selected.
%
% \subsection{Customising the Package}
%
% There's one command provided to customise the package.
% \DescribeMacro{\setfallbackfont}{\Macro{setfallbackfont}\Parameter{\textit{string}}}As
% described in the section before, this package will look for a
% character protrusion adjustment for a \emph{fallback} font, when not
% finding a |CPA| for the actual font. By default this is
% |pplmn|. That is changeable using |\setfallbackfont|, if a special
% |CPA| was created and suits better. The \emph{|string|} used in
% |\setfallbackfont| specifies the font \emph{without} the character
% encoding. That will be determined by the package.
%
% \subsubsection{System-wide customisation}
%
% For further customisation this package looks for a
% \DescribeOption{pdfcprot.cfg}{\Option{pdfcprot.cfg}}somewhere
% in your \TeX{} paths. If found it'll be included before any option is
% validated. So you can change some settings on a system-wide
% basis. This file is the best place to change some internal commands,
% if needed, for instance to change which fonts will be activated for
% character protruding when using the option |activate=normal| (by
% redefining |\CPROT@setupcharprotruding@normal|).
%
% \subsection{Other Commands and Options}
%
% Belonging not really to character protrusion this package provides
% two other commands and one additional option, that may be useful in
% dealing with pdf\TeX.
%
% First there's is an option to get a |DVI| output using pdf\TeX.
% \DescribeOption{DVIoutput}{\Option{DVIoutput}}This may be useful
% if one can't switch completely to pdf\TeX, because in this mode all
% the additional features of pdf\TeX\footnote{That's not completely
% true though. The supported type of images is in |DVI| mode the same
% as using |latex|.} (as character protruding) are
% available but besides there're no compatibility problems and it
% behaves the same as ``normal'' \LaTeX. So it is for instance possible to include
% |EPS| (and use |psfrag|!). Principally it is not needed to supply
% such an option, because by redefining |\pdfoutput| to |0| you'll get
% |DVI|. The only problem is, that some packages only look if
% |\pdfoutput| is defined to decide, if |PDF| output is
% wanted. So
% this option does an additional
% |\let\pdfoutput\undefined|.\footnote{Most actual versions of packages
% having had problems may treat it correctly by now. But who has all
% packages installed in most recent versions?}
%
% Further on there are two \LaTeXe{}-commands to decide, if pdf\TeX{}
% is used and if |PDF| as output is wanted.
% \DescribeMacro{\ifpdftex}{\Macro{ifpdftex}\Parameter{\emph{\texttt{true}}}\Parameter{\emph{\texttt{false}}}} and
% \DescribeMacro{\ifpdfoutput}{\Macro{ifpdfoutput}\Parameter{\emph{\texttt{true}}}\Parameter{\emph{\texttt{false}}}} 
% The latter one was originally 
% taken from the \KOMAScript{} package. So you can use
% the same |\ifpdfoutput| command with or without \KOMAScript. The
% meaning shouldn't change neither in \KOMAScript{} nor in this
% package and the actual definition is not cruel for using this
% command\footnote{If you want a \TeX{} \texttt{\bslash if} switch, look for \texttt{ifpdf.sty} on
% CTAN written by Heiko Oberdiek.}.
%
% The command |\ifpdftex| is very similar but leads to a decision
% depending on the usage of pdf\TeX{} or not. This is useful for the
% activation of special features of pdf\TeX{} not being special to the
% production of |PDF| itself (as character protruding is).
%
% \section{Bugs and Caveats}
%
% Hopefully there're no bugs left, but only features |;->|. But one
% thing: right now this package contains just character protruding
% settings for OT1 and T1 encoded fonts (and one character of TS1). Further there
% are some (small) problems (two).
%
% First, the creating of the code to do the adjustment of the character
% protruding at the |\begin{document}| is a bit time consuming. The
% more fonts you want to use with character protruding, the longer is the
% time needed. Also the needed memory by pdf\TeX{} can not be
% neglected. Here it's also especially a problem when using many fonts
% (in companion with character expansion it's just increasing). But
% that's not a big problem, because the standard amount of memory for
% pdf\TeX{} is for computer systems of today just a bit small
% adjusted (65535 bytes!). Though you may want to change (or set) the
% parameter |pdf_mem_size| in your |texmf.cnf|.\footnote{That is a
% suggestion of myself. I don't know what the authors of pdf\TeX{} say
% to that!.}
%
% \section{Contributing}
%
% Almost any contribution is welcome. Really needed is the
% contribution of |CPA|'s for other encodings than T1 and OT1. But T1
% and OT1 |CPA|'s may not be perfect. The glyphs are complete for
% German (I hope so) but I don't know for other languages.
%
% Also |CPA| for fonts not looking good with the distributed
% ``default'' values would be nice, even if these fonts are not widely
% used.
%
% Any bug hunting is welcome. Also changes to improve the performance
% are likely to be included, if the performance increase is
% significant and the readability of the package is not distorted too
% much (a good readability was a main focus when writing this package;
% that's one reason why almost on all places where possible \LaTeXe{}
% commands are used.).
%
% If you have some changes, requests, ideas or any other things
% regarding this package feel free to mail to Tobias Schlemmer:
% |keinstein_junior@gmx.net|.

% \section{Acknowledgements}
%
% All of the people are already mentioned in the text above, but I
% have to emphasise some things.
%
% For these bundle I used many from \KOMAScript. Particularly the
% boring but needed things around the package (|README.txt|,
% |INSTALL.txt| and the preambles in |pdcprot.ins|) were designed
% using files from \KOMAScript. In some parts I just changed
% \KOMAScript{} to |pdfcprot| (were appropriate). So I owe much to
% Markus Kohm (or the users of this package, because these files would
% be much shorter and maybe indistinct). As already stated there's
% some code taken from \KOMAScript.
%
% Further on some important role played Heiko Oberdiek (I don't think
% he guesses so). As stated in the History I first wanted to create a
% package for many (all) special pdf\TeX{} features (character
% protruding, font expansion, |PDF| security options). But he
% convinced me to write a package just concerning character
% protruding -- luckily, because it's got to more code than I expected
% first.
%
% And last but not least the authors of pdf\TeX{} have to be
% mentioned. Some code comes directly from them.

% \section{The Code Itself}
% 
% First some remarks: the documentation may be inaccurate in some
% places, so look at the code and it'll be very likely that the
% documentation is incomplete.

% The main attention writing this code
% was turned on creating a good human readable code. So I decided to
% use as much \LaTeXe{} control sequences as possible and as less
% \TeX{} commands as needed. This may slow down the code, but I don't
% think that's really important.
