% \begin{abstract}
%    This style file contains a set of definitions that allow keywords
%    to be defined and printed in several convenient ways.
%    For each keyword two definitions may be provided. This is to
%    allow the use of keywords in two contexts (for instance
%    English/French translation of the keywords).
%    At the same time, keyword can be printed in roman, teletype,
%    boldfaced or underlined.
%    The user can define other styles for printing keywords.
%    A set of keywords is provided by default. Of course a user can
%    define new keywords or redefine existing ones without modifying
%    the style file.

%
% When typing programs or algorithms, it often happens for a same
% text to appear as an algoritm (pseudo-code) or as a program. In such
% cases different fonts are used. For instance, algorithms may appear
% with keywords italicised or underlined, while the same keywords
% appear boldfaced in the program text.
% Moreover algorithms are often typed with keywords belonging to the
% native language of the writer while program keywords appear usually
% to be english ones.
%
% The file {\em{}keywords.sty\/} provides simple solutions to both of
% these problems by giving the user capability to define each keyword
% in two simultaneaous different manners and by providing different
% printing styles.
%
% Keywords are commands to be issued in text. Hence this style file is
% origimally intended to be used in conjunction with the features
% provided by the {\em{}programs.sty\/} style file~\cite{alabau95-d}.
% However, it can be used independently.
%
% \ifnoprogsfile \relax\else
%
% For instance, let be the following piece of program:
%
% \begin{verbatim}
%     \BEGIN
%         statements
%     \END
% \end{verbatim}
%
% \vspace{-\baselineskip}
% \noindent%
% where \verb+\BEGIN+ and \verb+\END+ are two predefined commands in
% this style file. 
% If we issue the command \verb+\ProgKeywords+, then we get:
%
% \ProgKeywords
% \begin{programf}*
%     \BEGIN
%         statements
%     \END
% \end{programf}
%
% \vspace{-\baselineskip}
% \noindent%
% If we prefer to use the second language, we can issue the
% \verb+\FProgKeywords+:
%
% \FProgKeywords
% \begin{programf}*
%     \BEGIN
%         statements
%     \END
% \end{programf}
%
% \vspace{-\baselineskip}
% \noindent%
% We can also use other typesetting rules, like underlined emphasized
% fonts (\verb+UAlgoKeywords+):
%
% \UAlgoKeywords
% \begin{programf}*
%     \BEGIN
%         statements
%     \END
% \end{programf}
%
% \vspace{-\baselineskip}
% \noindent%
% It is also possible to define new keywords or to redefine existing
% ones, by issuing a command like:
%
% \begin{verbatim}
% \NewKeyword{\BEGIN}{this is the beginning}
% \NewKeyword{\END}{this is the end}
% \end{verbatim}
%
% \vspace{-\baselineskip}
% \noindent%
% which leads to the following piece of code (default typesetting used
% is the last one specified, i.e. \verb+UAlgoKeywords+):
%
% \NewKeyword{\BEGIN}{this is the beginning}
% \NewKeyword{\END}{this is the end}
% \begin{programf}*
%     \BEGIN
%         statements
%     \END
% \end{programf}

% \section{User's Manual}
%
% A set of default keywords is provided in this file (see
% section~\ref{default-keywords}). For each keyword, two definitions
% are provided: the first one in english, and the second one in french
% (because I am French).
% The switch between the two languages is performed by global commands
% wich serve also to define the font used for printing.

%
% \DescribeMacro{\ProgKeywords}
% \DescribeMacro{\FProgKeywords}

%
% The following printing styles are provided:
%
% \begin{center}
% \begin{tabular}{lll}
%     \hline
%     \multicolumn{1}{c}{style}
%     & \multicolumn{1}{c}{definition~1}
%     & \multicolumn{1}{c}{definition~2}\\
%     \hline\hline
%     \verb+\bf+            & \verb+\ProgKeywords+   & \verb+\FProgKeywords+\\
%     \verb+\tt+            & \verb+\ttKeywords+     & \verb+\FttKeywords+\\
%     \verb+\em+            & \verb+\AlgoKeywords+   & \verb+\FAlgoKeywords+\\
%     \verb+\rm+            & \verb+\NormalKeywords+ & \verb+\FNormalKeywords+\\
%     \hline
% \end{tabular}
% \end{center}
%
% \DescribeMacro{\UAlgoKeywords}
% \DescribeMacro{\UFAlgoKeywords}
% \DescribeMacro{\FUAlgoKeywords}
% There are also two underlined styles:
%
% \begin{center}
% \begin{tabular}{lll}
%     \hline
%     \multicolumn{1}{c}{style}
%     & \multicolumn{1}{c}{definition~1}
%     & \multicolumn{1}{c}{definition~2}\\
%     \hline\hline
%     underlined \verb+\em+ & \verb+\UAlgoKeywords+  & \verb+\FUAlgoKeywords+\\
%     \hline
% \end{tabular}
% \end{center}
%
% For compatability with previous versions of keywords.sty, the
% command \verb+\UFAlgoKeywords+ has been defined as a synonym for
% \verb+\FUAlgoKeywords+.
%
% \subsection{Defining and Re-defining keywords}
% \label{user:program-keywords}
%
% \DescribeMacro{\NewKeyword}
% The command
%
% \begin{verbatim}
%     \NewKeyword{\WORD}{SENTENCE1}[SENTENCE2]
% \end{verbatim}
%
% \vspace{-\baselineskip}
% defines the command \verb+\WORD+ to issue the text in
% \verb+SENTENCE1+ or in \verb+SENTENCE2+ when it is typed, according
% to the style currently in use.
%
% For instance, one could use \verb+SENTENCE1+ for defining english
% keywords and \verb+SENTENCE2+ for defining their french translation.
%
% If ``\verb+[SENTENCE2]+'' is omitted, all happens as if the
% following command had been issued: 
%
% \begin{verbatim}
%     \NewKeyword{\WORD}{SENTENCE1}[SENTENCE1]
% \end{verbatim}
%
% \vspace{-\baselineskip}
% The command \verb+\NewKeyword+ serves also to redefine existing
% keywords. 
%
% \subsection{Defining a printing style}
% \label{user:defining-printing-styles}
%
% \DescribeMacro{\DefineKeywordsStyles}
% The command 
%
% \begin{verbatim}
%     \DefineKeywordsStyles{MODE}{\STYLE}
% \end{verbatim}
%
% \vspace{-\baselineskip}
% allows for the user to define particular printing modes.
% Its main effect is to define the commands \verb+\MODEs+ and
% \verb+\FMODEs+ that will lead to print respectively the
% \verb+SENTENCE1+ part or the \verb+SENTENCE2+ part of the
% \verb+\NewKeyword+ definitions.
% For instance, the commands \verb+\ProgKeywords+ and
% \verb+\FProgKeywords+ have been automatically defined from a
% \verb+\DefineKeywordsStyles{ProgKeyword}{\bf}+ command.
%
% \DescribeMacro{\DefineUnderlinedKeywordsStyles}
% \ \\
% For \verb+SENTENCE+$_i$ to be underlined, it is necessary to issue a 
%
% \begin{verbatim}
%     \DefineUnderlinedKeywordsStyles{MODE}{\STYLE}
% \end{verbatim}
%
% \vspace{-\baselineskip}
% command, instead of the ``\verb+\DefineKeywordsStyles+'' described
% above. 
% This is how the \verb+\UAlgoKeywords+ and \verb+\FUAlgoKeywords+
% commands have been defined, by issuing a
% \verb+\DefineUnderlinedKeywordsStyles{UAlgoKeyword}{\em}+ command.
%
% \subsection{The Index File}
%
% In order for the processing of this file to be complete, an index
% format file is required. Let us assume that it is named
% \verb+keywords.ist+, then the following command must be run and then
% another compilation of the current file:
%
%    \begin{macrocode}
%<index>
%<index>%% -----------------------------------------------------------
%<index>%% Assuming this file is named "keywords.ist" (after being
%<index>%% generated from "keywords.dtx" by running "latex docstrip"),
%<index>%% the following command will produce a well formated index:
%<index>%% 
%<index>%%                  makeindex -s keywords.ist keywords.idx
%<index>%% -----------------------------------------------------------
%<index>
%    \end{macrocode}
%
% Another possibility is to set the environment variable
% \verb+INDEXSTYLE+ to a directory name where the ``.ist'' files
% (index format files) may be found.
%
% A possible index file is given below\footnote{It can be generated by
% invoquing the compilation of ``docstrip'' with the ``index''
% option.}: 
%
%    \begin{macrocode}
%<index>actual '='
%<index>quote '!'
%<index>level '>'
%<index>preamble
%<index>"\n \\begin{theindex} \n \\makeatletter\\scan@allowedfalse\n"
%<index>postamble
%<index>"\n\n \\end{theindex}\n"
%<index>item_x1   "\\efill \n \\subitem "
%<index>item_x2   "\\efill \n \\subsubitem "
%<index>delim_0   "\\pfill "
%<index>delim_1   "\\pfill "
%<index>delim_2   "\\pfill "
%<index>% The next lines will produce some warnings when
%<index>% running Makeindex as they try to cover two different
%<index>% versions of the program:
%<index>lethead_prefix   "{\\bf\\hfil "
%<index>lethead_suffix   "\\hfil}\\nopagebreak\n"
%<index>lethead_flag       1
%<index>heading_prefix   "{\\bf\\hfil "
%<index>heading_suffix   "\\hfil}\\nopagebreak\n"
%<index>headings_flag       1
%    \end{macrocode}
%
% \subsection{The Driver File}
%
% There is also a driver file, called {\em{}programs.drv\/}, that is
% included in the distribution. 
% It is devoted to control the latex compilation of the documentation.
% Its code is given below.
%

%    \end{macrocode}
%
% \subsection{Extracting the documents included in the file keywords.dtx}
%
% There are three documents included in the {\em{}keywords.dtx\/} file:
% the style file ({\em{}keywords.sty}),
% the index style file for printing a cross-referenced document
% ({\em{}keywords.ist}),
% and the driver file for printing the document: {\em{}keywords.drv\/}.
%
% For file extraction it is necessary to use the \verb"docstrip"
% utility, which is part of the \verb"doc"
% distribution~\cite{art:doc}. 
% Normally, a file \verb"docstrip.tex" should exist on the \LaTeX\
% style files directory.
% Extraction is performed by typing:
%
% \begin{verbatim}
%    latex docstrip
% \end{verbatim}
%
% \vspace{-\baselineskip}
% This is an interactive program, and the dialogue for generating the
% style file should be:
%
% \begin{verbatim}
%    **********************************************************
%    * This program converts documented macro-files into fast *
%    * loadable files by stripping off (nearly) all comments! *
%    **********************************************************
%    
%    ****************************************************
%    * First type the extension of your input file(s):  *
%    \infileext=doc
%    ****************************************************
%    
%    ****************************************************
%    * Now type the extension of your output file(s)  : *
%    \outfileext=sty
%    ****************************************************
%    
%    ****************************************************
%    * Now type the name(s) of option(s) to include   : *
%    \Options=style
%    ****************************************************
%    
%    ****************************************************
%    * Finally give the list of input file(s) without   *
%    * extension seperated by commas if necessary     : *
%    \filelist=Programs
%    ****************************************************
% \end{verbatim}
%
% \vspace{-\baselineskip}
% For generating the index file it suffices to rerun the
% \verb"docstrip" utility and to answer ``ist/index'' instead of
% ``sty/style'' int the above steps~2 and~3.
%
% \medskip
%
% The three files may be produced in a single pass, by simply latexing
% the file {\em{}keywords.ins\/} which goes along with the file
% {\em{}keywords.dtx\/}. 
%
% \medskip
%
% Generation of the documentation is then simply performed as follows
% (the {\em{}keywords.dtx\/} file includes its own driver):
%
% \begin{verbatim}
%    latex keywords.dtx
%    latex keywords.dtx
%    latex keywords.dtx
%    makeindex  -s keywords.ist keywords.idx
%    latex keywords.dtx

%
% \begin{macro}{\AlreadyDefined@@Keywords}
%    This macro can be tested by any style file to know if the file
%    ``{\sf{}keywords.sty}'' has been input. But it allows a modular
%    programming style similar to the one used with the C~header
%    files. 
%    Hence, the first time the ``{\sf{}keywords.sty}'' style file is
%    included all of its body will be included; the second time, the
%    body will not be included.
%    \begin{macrocode}
\expandafter\ifx\csname AlreadyDefined@@Keywords\endcsname\relax%
\expandafter\def\csname AlreadyDefined@@Keywords\endcsname{}%
\else\endinput\fi
%    \end{macrocode}
% \end{macro}%
%
%    A test for the existence of this macro is performed for
%    compatability with ancient versions of \LaTeX.

\def\NewKeyword#1#2{\@ifnextchar[{\@@newkwrd{#1}{#2}}{\@@newkwrd{#1}{#2}[#2]}}
%    \end{macrocode}
% \end{macro}
%
%    The \verb+\@@newkwrd+ performs the real work. It calls the
%    command \verb+\@@KeywordsCurrentStyle+ whose effect is to define
%    the command \verb+\@@kwrd+ and then invokes this last command.
%    \begin{macrocode}
\def\@@newkwrd#1#2[#3]{\def#1{\@@KeywordsCurrentStyle{\@@kwrd}{#2}{#3}\@@kwrd}}
%    \end{macrocode}
% \end{macro}

% \subsection{Defining printing styles}
%
% \begin{macro}{\@@TypeStyle}
%     This command is expected to be called with a command name as
%     first parameter. Its effect is to define \verb+#1+ as the
%     command that print \verb+#3+ with style \verb+#2+~:
%    \begin{macrocode}
\def\@@TypeStyle#1#2#3{\def#1{\mbox{\reset@font#2{}#3\/}}}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\DefineKeywordsStyles}
%     The macro \verb+\DefineKeywordsStyles+ has two parameters, let
%     them be \verb+toto+ and \verb+bf+. Its effect is to define
%     two commands called \verb+\@@toto+ and \verb+\F@@toto+. Each of
%     these two new commands has three parameters: the first one must
%     be the name of a command (the keyword to be defined) and the
%     other two must be two texts associated to the keyword. The
%     \verb+\@@toto+ command will select the first text while the
%     \verb+\F@@toto+ command will select the second text.
%    \begin{macrocode}
\newif\if@@underline \@@underlinefalse
\def\DefineKeywordsStyles#1#2{
    \if@@underline
        \@namedef{@@#1}##1##2##3{\@@TypeStyle{##1}{#2}{\underline{##2}}}
        \@namedef{F@@#1}##1##2##3{\@@TypeStyle{##1}{#2}{\underline{##3}}}
    \else
        \@namedef{@@#1}##1##2##3{\@@TypeStyle{##1}{#2}{##2}}
        \@namedef{F@@#1}##1##2##3{\@@TypeStyle{##1}{#2}{##3}}
    \fi
%    \end{macrocode}
%    A boolean switch is used to select underlined fonts. By default
%    non underlined fonts are used, and a reset to non boolean fonts
%    is performed after every definition of keyword:
%    \begin{macrocode}
    \@@underlinefalse
%    \end{macrocode}
%    At last two commands are provided to the user: \verb+\totos+ and
%    \verb+\Ftotos+ whose effect is to set the command
%    \verb+\@@KeywordsCurrentStyle+ respectively to \verb+\@@toto+ or
%    \verb+\F@@toto+~:
%    \begin{macrocode}
    \@namedef{#1s}{\def\@@KeywordsCurrentStyle{\@nameuse{@@#1}}}
    \@namedef{F#1s}{\def\@@KeywordsCurrentStyle{\@nameuse{F@@#1}}}
}
%    \end{macrocode}
%     By this way when a command 
%
%     \begin{verbatim}
%         \NewKeyword{\WORD}{SENTENCE1}[SENTENCE2]
%     \end{verbatim}
%
%     \vspace{-\baselineskip}
%     is issued, then \verb+\WORD+ is defined to
%
%     \begin{verbatim}
%         \@@KeywordsCurrentStyle{\@@kwrd}{SENTENCE1}{SENTENCE2}\@@kwrd}
%     \end{verbatim}
%
%     \vspace{-\baselineskip}
%     Hence, every time the command \verb+\WORD+ is issued by the
%     user in the text of its programs, \verb+\@@kwrd+ is redefined
%     and invoked under the running definition of
%     \verb+\@@KeywordsCurrentStyle+. 
%     This complicated trick ensures that every keyword, even if it is
%     not defined in the style file (e.g. if it is defined in the text
%     typed by the user) will be typed with the correct font selection.
% \end{macro}

% \begin{macro}{\DefineUnderlinedKeywordsStyles}
%     This macro serves to switch to underlined fonts:
%    \begin{macrocode}
\def\DefineUnderlinedKeywordsStyles#1#2{
    \@@underlinetrue
    \DefineKeywordsStyles{#1}{#2}
}
%    \end{macrocode}
% \end{macro}

% \subsection{Predefined printing styles}

% section~\ref{user:selecting-printing-styles}) by issuing the
