%   History: 
%
%   - October 27 2003  - revision 2.51 - Revision submitted to CTAN archive
%                        * correction of a minor which make caption in procedure
%                          and function to be blanck with pdfscreen package
%                          (thanks to Joel Gossens for the notification)
%                        * add two internal definition to avoid some errors when
%                          used with Hyperref package (Hyperref package need to
%                          define new counter macro from existing ones, and
%                          don't do it for algorithm2e package, so we do it)
%
%   - October 17 2003  - revision 2.50 - first revision for CTAN archive
%
%                        * add \AlFnt and \SetAlFnt{font} macros:
%                          \AlFnt is used at the beginning of the caption and the
%                          body of algorithm in order to define the fonts used
%                          for typesetting algorithms. You can use it elsewhere
%                          you want to typeset text as algorithm. For example
%                          you can do \SetAlFnt{\small\sf} to have algorithms
%                          typeset in small sf font. Default is nothing so
%                          algorithm is typeset as the text of the document.
%                        * add \AlTitleFnt{text} and \SetAlTitleFnt{font} macros:
%                          The {Algorithm: } in the caption is typeset with
%                          \AlTitleFnt{Algorithm:}. You can use it to have text
%                          typeset as {Algorithm:} of captions. Default is
%                          textbf.
%                          Default can be redefined by \SetAlTitleFnt{font}.
%                        * add CommentSty typo for text comment.
%                        * add some compatibility with hyperref package (still
%                          an error on multiply defined refs but pdf correctly
%                          generated)
%                        * flush text to left in order to have correct
%                          indentation even with class as amsart which center
%                          all figures
%                        * add german, portugues and czech options for title of
%                          algorithms and typo.
%                        * add portuguese translation of predefined keywords
%                        * add czech translation of some predefined keywords
%
%   - December 23 2002 - revision 2.40
%                        * add some french keyword missing
%                        * add function* and procedure* environment like
%                          algorithme* environment: print in one column even
%                          if twocolumn option is specified for the document.
%                        * add a new macro \SetKwComment to define macro which
%                          writes comments in the text. First argument is the
%                          name of the macro, second is the text put before the
%                          comment, third is the text put at the end of the
%                          comment.Default are \tcc and \tcp
%                        * add new options to change the way algo are numbered:
%                          [algopart] algo are numbered within part (counter must exist)
%                          [algochapter] algo are numbered within chapter
%                          [algosection] algo are numbered within section
%
%   - March 27 2002   - revision 2.39
%                      Gilles Geeraerts: added the \SetKwIfElseIf to manage
%                      if (c)
%                           i;
%                      else if (c)
%                           i;
%                      ...
%                      else
%                           i;
%                      end
%                      Also added \gIf \gElsIf \gElse.
%
%   - January 02 2001 - revision 2.38
%                      bugs related to the caption in procedure and function
%                      environment are corrected.
%                      bug related to option noend (extra vertical space added
%                      after block command as If or For) is corrected.
%                      czech option language added (thanks to Libor Bus: l.bus@sh.cvut.cz).
%  
%   - October 16 2000 - revision 2.37
%                      option algo2e added: change the name of environment
%                      algorithm into algorithm2e. So allow to use the package
%                      with some journal style which already define an algorithm
%                      environment.
%  
%   - September 13 2000 - revision 2.36
%                      option slide added: require package color
%                      Hack for slide class in order to have correct
%                      margins
%  
%   - November 25 1999 - revision 2.35
%                      revision number match RCS number
%                      Thanks to David A. Bader, a new option is added:
%                      noend: no end keywords are printed.
%  
%   - November 19 1999 - revision 2.32
%                      minor bug on longend option corrected.
%  
%   - August 26 1999 - revision 2.31
%                    add an option : figure
%                    this option treats algorithms as figure and so are numbered
%                    as figures and putted in the \listoffigures
%  
%   - January 21 1999 - revision 2.3 beta
%                    add 2 new environments: procedure and function.
%                    These environments works like algorithm environment but:
%                    - the ruled (or algoruled) style is imperative.
%                    - the caption now writes Procedure name....
%                    - the syntax of the \caption command is restricted as
%                      follow: you MUST put a name followed by 2 braces like
%                      this ``()''. You can put arguments inside the braces and
%                      text after. If no argument is given, the braces will be
%                      removed in the title. 
%                    - label now puts the name (the text before the braces in the
%                      caption) of the procedure or function as reference (not
%                      the number like a classic algorithm environment).
%                    There are also two new styles : ProcNameSty and
%                    ProcArgSty. These style are by default the same as FuncSty
%                    and ArgSty but are used in the caption of a procedure or a
%                    function.
%                    
%   - November 28 1996 - revision 2.22
%                    add a new macro \SetKwInParam{arg1}{arg2}{arg3}:
%                    it defines a macro \arg1{name}{arg} which prints name in keyword
%                    style followed byt arg surrounded by arg2 and arg3. The main
%                    application is to a function working as \SetKwInput to be used
%                    in the head of the algorithm. For example
%                    \SetKwInParam{Func}{(}{)} allows
%                    \Func{functionname}{list of arguments} which prints:
%                    \KwSty{functioname(}list of arguments\KwSty{)}
%       
%
%   - November 27 1996 - revision 2.21 :
%                    minor bug in length of InOut boxes fixed.
%                    add algorithm* environment.
%
%   - July 12 1996 - revision 2.2 : \SetArg and \SetKwArg macros removed.
%                        
%                    \SetArg has been removed since it never has been
%                    documented.
%                    \SetKwArg has been removed since \SetKw can now
%                    take an argument in order to be consistent with
%                    \SetKwData and \SetKwFunction macros.
%
%   - July 04 1996 - revision 2.1 : still more LaTeX2e! Minor compatibility break
%
%                    Macros use now \newcommand instead of \def, use of \setlength, 
%                    \newsavebox, ... and other LaTeX2e specific stuff.
%                    The compatibility break:
%                    - \SetData becomes \SetKwData to be more consistent. So the old 
%                      \SetKwData becomes \SetKwInput
%                    - old macros \titleofalgo, \Freetitleofalgo and \freetitleofalgo
%                      from LaTeX209 version which did print a warning message and call 
%                      \Titleofalgo in version 2.0 are now removed!
%
%   - March 13 1996 - revision 2.0: first official major revision.

%
%   Known bugs: 
%   -----------
%   - [H] option of algorithm environment doesn't work with * environments
%     (ie. algorithm*). This is due to floats defined with float package (as
%     algorithms are) and so can't be
%     adressed here.
%   - [figure] option is not compatible with floatflt package, in fact
%     \texttt{caption} of floatingfigure are not compatible. \Optfigure restyle
%     algo as figure, so caption of figure uses \texttt{float} package
%     caption. \texttt{floatflt} package is declare as a figure but doesn't call
%     some \texttt{figure} macro as in the original and so some stuffs are not
%     defined correctly which makes a bug. If someone find a solution to this
%     problem, I will be glad to include its contribution and thanks him.
%
%%%%%%%%%%%%%%
%
%   Package options: 
%   ---------------
%   - french, english               : for the name of the algorithm, e.g.
%   - boxe, ruled, algoruled, plain : layout of the algorithm
%   - noline,lined,vlined           : how block are designed.
%   - titlenumbered,titlenotnumbered: numbering of title set by \Titleofalgo
%   - resetcount, noresetcount      : start value of line numbers.
%   - algonl                        : line numbers preceded by algo number
%   - shortend, longend             : short or long end keyword as endif for e.g.
%  
%   defaults are; english,plain,resetcount,titlenotnumbered

%
%   Short summary  
%   -------------
%  
%   algorithm is an environment for writing algorithm in LaTeX2e
%   It provide macros that allow you to create differents
%   sorts of key words, therefore a set of predefined key word
%   is gived.
%
%   IT should be used as follows
%
%   \begin{algorithm}
%       ...
%       ...
%   \end{algorithm}
%
%
%   IMPORTANT : each line MUST end with \;
%
%   Note that if you define macros outside algorithm environment they
%   are avaible in all the document and particulary you can use then
%   inside all algorithms without re-define them.
%  
%   an example:
%
%   \begin{algorithm}[H]
%     \SetLine
%     \AlgData{this text}
%     \AlgResult{how to write algorithm with \LaTeX2e }
%

%     \While{not at end of this document}{
%       read current section\;
%       \eIf{understand}{
%         go to next section\;
%         current section becomes this one\;
%         }{
%         go back to the beginning of current section\;
