+Installation
+============
+
+Installing `barracuda` for TeX Live
+-----------------------------------
+
+If you have TeX Live installed from CTAN or from DVD TeX Collection, before
+any modification to your system check if the package is already installed
+looking for `installed` key in the output of the command:
+
+ $ tlmgr show barracuda
+
+If `barracuda` is not present, run the command:
+
+ $ tlmgr install barracuda
+
+If you have installed TeX Live via Linux OS repository try your distribution's
+package management system.
+
+It's also possible a manual installation:
+
+ a. Grab the sources from CTAN or https://github.com/robitex/barracuda .
+ b. Unzip it at the root of one or your TDS trees.
+ c. You may need to update some filename database after this running `texhash`,
+    see your TeX distribution's manual for details.
+
+Any TeX Live documentation files can be easily opened on screen with the
+`texdoc` command line utility (this way is very handy).
+
+ $ texdoc pkgname
+
+Installing for Lua
+------------------
+
+Manually copy the `src` folder content to a suitable directory of your system
+that is reachable to a Lua interpreter.

+GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                          675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	Appendix: How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+# `barracuda` project
+
+This Lua library is for drawing barcode symbols. The project delivers modules
+to typeset barcode from within a LuaTeX document. Therefore is also possible
+to use `barracuda` with a Lua standalone interpreter to draw barcodes with
+different graphic format such as `SVG` (see an example below).
+This package does not have dependences.
+
+![a SVG formatted Code39 symbol](/test/test-ga-svg/test-code39.svg)
+
+Internal modules is structured to ensure good performance and to allow a
+complete user control over barcode symbol parameters :thumbsup: .
+
+Although development is in beta stage, `barracuda` has a good level of
+stability.
+
+## Current version information
+
+Version: v0.0.9.1
+Date: 2019-12-04
+
+## Barcode symbologies list
+
+So far, are supported
+
+- Code 39
+- Code 128
+- Interleaved 2 of 5
+- EAN family (EAN8, EAN13, and the add-ons EAN5 and EAN2)
+
+Other 1D encoding symbology will be added to the project, then it will be the
+turn of 2D barcode types like Datamatrix, QRCode or PDF417.
+
+## A very simple LaTeX example
+
+The LaTeX package `barracuda.sty` under the cover uses Lua code so you need to
+compile your source files with LuaTeX or LuajitTeX with the LaTeX format.
+
+For instance, here there is a minimal example for LuaLaTeX:
+
+```latex
+% !TeX program = LuaLaTeX
+\documentclass{article}
+\usepackage{barracuda}
+\begin{document}
+\barracuda{code39}{123ABC}
+\end{document}
+```
+
+## Documentation
+
+Details and package reference can be found in the manual delivered in the `doc`
+project directory, even if it is very minimal at the moment.
+
+Directory `test` contains files useful also for code examples.
+
+## Installation
+
+The `barracuda` package can be used with pure Lua interpreter or from within a
+TeX source file for Lua-powered typesetting engine like LuaTeX. In the first
+case you can manually copy `src` folder content to a suitable directory of
+your system. Otherwise, you can install the package via `tlmgr` for your TeX
+Live distribution.
+
+If you have installed TeX Live with the `full` schema, `barracuda` is just
+available and no further action is required. Please, take into account that
+only the tagged version (in the `git` sense) of the package will be sent to
+CTAN. This means that intermediate development version between consecutive
+releases can be found only at https://github.com/robitex/barracuda .
+
+TeX Live distribution or Lua interpreter executable are available for a very
+large number of Operating Systems so it is also for `barracuda`.
+
+Step by step istruction can be found in the INSTALL.txt file.
+
+## Contribute
+
+Contributes are welcome in any form and for any topics. You can contact me
+directly via email at giaconet.mailbox@gmail.com or via a pull request on the
+repository https://github.com/robitex/barracuda or writing a public message
+via the web page https://github.com/robitex/barracuda/issues for todos, bugs,
+feature requests, and more (press the bottom `New issue`).
+
+Anyway, as a starting point take a look of TODO.txt file for the next
+scheduled development tasks.

+Welcome to the \brcd{} software project devoted to barcodes printing.
+
+This manual shows you how to print barcodes in your \TeX{} documents and how to
+export such graphic content to an external file, using \brcd{}.
+
+\brcd{} is written in Lua programming language and is free software released
+under the GPL 2 License.%

+
+
+\section{Introduction}
+
+Barcode symbols are usually a sequence of vertical lines representing encoded
+data that can be retrived with special laser scanner or more simpler with a
+smartphone running dedicated apps. Almost every store item has a label with a
+printed barcode for automatic identification purpose.
+
+So far, \brcd{} supported symbologies are as the following:
+\begin{itemize}
+	\item Code 39,
+	\item Code 128,
+	\item EAN family (EAN 8, EAN 13, and the add-ons EAN 2 and EAN 5),
+	\item ITF 2of5, interleaved Two of Five.
+\end{itemize}
+
+The package provides drivers for different graphic format, at the moment are:
+\begin{itemize}
+	\item PDF Portable Document Format (require a modern \TeX{} engine),
+	\item SVG Scalable Vector Graphic.
+\end{itemize}
+
+The name \brcd{} is an assonance with the name Barcode. I started the project
+back in 2016 for getting barcode in my \TeX{} generated PDF documents, studying
+the Lua\TeX{} technology.
+
+
+\subsection{Manual Content}
+
+The manual is divided into three parts. At section~\ref{secEnter} the first look
+gives to the user a proof of concept to how to use and how works the package
+while the next parts present details like how to change the \emph{module} width
+of a EAN-13 barcode or how to implement a barcode symbology not already included
+in the package.
+
+The plan of the manual is (but some sections are not completed yet):
+\begin{description}
+\item[Part 1:] Get started
+\begin{itemize}
+	\item print your first barcode \( \to \) \ref{secEnter}
+	\item installing \brcd{} on your system \( \to \) \ref{secInstall}
+	\item \brcd{} \LaTeX{} package \( \to \) \ref{secLaTeXPkg}
+\end{itemize}
+\item[Part 2:] Advanced Work with \brcd{}
+\begin{itemize}
+	\item Lua framework description \( \to \) \ref{secFramework}
+	\item working example and use cases \( \to \) \ref{secExample}
+\end{itemize}
+\item[Part 3:] Reference and parameters
+\begin{itemize}
+	\item barcode symbology reference \( \to \) \ref{secBcRef}
+	\item \code{ga} specification
+	\item API reference \( \to \) \ref{secAPI}
+\end{itemize}
+\end{description}
+
+\subsection{Required knowledge and useful resources}
+
+The \brcd{} is a Lua package that can be executed by any Lua interpreter. To use
+it, it's necessary some knowledge of Lua programming language and a certain
+ability with the terminal of your computer system in order to accomplish command
+tasks or software installations.
+
+It's also possible to run \brcd{} directly from within a \TeX{} source file,
+compiled with a suitable typesetting engine like Lua\TeX{}. To do so a minimal
+\TeX{} system knowledge is required. As an example of this workflow you simply
+can look to this manual because itself is typesetted with LuaLa\TeX{}, running
+\brcd{} to include barcodes as a vector graphic object.
+
+Here is a collection of useful learning resources\dots

+\section{Get Started with Barracuda}
+\label{secEnter}
+
+The starting point to work with \brcd{} is always a plain text file with some
+code, late processed by a command line program with a Lua interpreter.
+
+As a practical example producing an EAN-13 barcode, in a text editor of your
+choice on a empty file called \code{first-run.lua}, type the following two lines
+of code:
+\medskip
+\begin{Verbatim}[label=\footnotesize\code{first-run.lua}]
+local barracuda = require "barracuda"
+barracuda:save("ean-13", "8006194056290", "my_barcode", "svg")
+\end{Verbatim}
+
+What you have done is to write a \emph{script}. If you have installed a Lua
+interpreter and \brcd{}, open a terminal and run the command:
+\begin{Verbatim}
+$ lua first-run.lua
+\end{Verbatim}
+
+You will see in the same directory of your script, appearing the new file
+\code{my\_barcode.svg} with the drawing:
+\begin{center}
+\includegraphics{image/8006194056290}
+\end{center}
+
+Coming back to the script \code{first-run.lua}, first of all, it's necessary to
+load the library with the standard statement \code{require()}. What that Lua
+function returns is an object---more precisely a table reference---where are
+stored every package features.
+
+We can now produce the EAN-13 barcode using the method \code{save()} of the
+\brcd{} object. The \code{save()} method takes in order the barcode symbology
+identifier, the data to be encoded as a string or also a whole number, the
+output file name and the optional output format.
+
+
+\subsection{Running Lua\TeX}
+
+Barracuda can also running inside Lua\TeX{} and the others Lua powered \TeX{}
+engine. The text source file is a bit difference respect to a Lua script: Lua
+code have to bring place as the argument of directlua primitive... we must use
+a box register of type horizontal...
+
+\begin{Verbatim}
+% !TeX program = LuaTeX
+\nopagenumbers
+\newbox\mybox
+\directlua{
+	local require "barracuda"
+	barracuda:hbox("ean-13", "8006194056290", "mybox")
+}\box\mybox
+\bye
+\end{Verbatim}
+
+The method \code{hbox()} works only with Lua\TeX{}.
+
+
+\subsection{A more deep look}
+
+Barracuda is designed to be modular and flexible. For example it is possible
+to draw different barcodes on the same canvas or tune barcode parameters. 
+
+The main workflow to draw a barcode object reveals more details on internal
+structure. In fact, to draw an EAN-13 barcode we must do at least the following
+steps:
+\begin{enumerate}
+\item load the library,
+\item get a reference to the \code{Barcode} class,
+\item build an EAN encoder,
+\item build an EAN symbol passing data to a costructor,
+\item get a reference to a new canvas object,
+\item draw barcode on canvas,
+\item get a reference of driver object,
+\item address canvas toward a driver.
+\end{enumerate}
+
+Follow that step by step procedure the corresponding code is in the next
+listing:
+\begin{Verbatim}
+local barracuda = require "barracuda"
+local barcode = barracuda:get_barcode_class()
+
+local ean13, err_enc = barcode:new_encoder("ean-13")
+assert(ean13, err_enc)
+
+local symb, err_symb = ean13:from_string("8006194056290")
+assert(symb, err_symb)
+
+local canvas = barracuda:new_canvas()
+symb:append_ga(canvas)
+
+local driver = barracuda:get_driver()
+local ok, err_out = driver:save("svg", canvas, "my_barcode", "svg")
+assert(ok, err_out)
+\end{Verbatim}
+
+
+\section{Installing}
+\label{secInstall}
+
+\subsection{Installing `barracuda` for TeX Live}
+
+If you have TeX Live installed from CTAN or from DVD TeX Collection, check
+before any modification to your system if the package is already installed
+looking for \emph{installed} key in the output of the command:
+\begin{Verbatim}
+$ tlmgr show barracuda
+\end{Verbatim}
+
+If `barracuda` is not present, run the command:
+\begin{Verbatim}
+$ tlmgr install barracuda
+\end{Verbatim}
+
+If you have installed TeX Live via Linux OS repository try your distribution's
+package management system.
+
+It's also possible a manual installation:
+\begin{enumerate}
+\item Grab the sources from CTAN or \url{https://github.com/robitex/barracuda}.
+\item Unzip it at the root of one or your TDS trees.
+\item You may need to update some filename database after this, see your \TeX{}
+distribution's manual for details.
+\end{enumerate}
+
+\subsection{Installing for Lua}
+
+Manually copy \code{src} folder content to a suitable directory of your system
+that is reachable to Lua interpreter.
+
+
+\section{Barracuda \LaTeX{} Package}
+\label{secLaTeXPkg}
+
+The \LaTeX{} package delivered with \brcd{} is still under an early stage of
+development. The only macro available is \verb=\barracuda{encoder}{data}=.
+A simple example is the following source file for Lua\LaTeX{}:
+\begin{Verbatim}
+% !TeX program = LuaLaTeX
+\documentclass{article}
+\usepackage{barracuda}
+\begin{document}
+\leavevmode
+\barracuda{code39}{123ABC}\\
+\barracuda{code128}{123ABC}
+\end{document}
+\end{Verbatim}
+
+Every macro \verb=\barracuda= typesets a barcode symbol represented with the
+encoder defined in the first argument, the information defined by the second.
+
+
+\section{The Barracuda Framework}
+\label{secFramework}
+
+The \brcd{} package framework consists in indipendet modules: a barcode class
+hierarchy encoding a text into a barcode symbology; a geometrical library called
+\code{libgeo} representing several graphic object; an encoding library for the
+\code{ga} format (graphic assembler) several driver to "print" a ga stream
+into a file or a \TeX{} hbox register.
+
+To implement a barcode encoder you need to write a component called
+\emph{encoder} defining every parameters and producing the encoder class, while
+a driver must understand ga opcode stream and print the corresponding graphic
+object.
+
+Every barcode encoder come with a set of parameters, some of them can be
+reserved and can be setting up by the user only through the encoder.
+
+So, you can create many instances of the same encoder for a single barcode
+type, with its own parameter set.
+
+The basic idea is getting faster encoder, for which the user may set up
+paramenters at any level: barcode abstract class, encoder, down to a single
+symbol.
+
+Barcode class is completely indipendent from the ouput driver and viceversa.

+Code 128 encoder test.
+
+Test 1: one simple barcode with default parameter:
+
+\directlua{
+barracuda = require "barracuda"
+}
+
+\directlua{
+local barcode = barracuda:get_barcode_class()
+
+local c128, err = barcode:new_encoder("code128")
+assert(not err, err)
+
+local symbo, err = c128:from_string("5465468132546812")
+assert(not err, err)
+
+local canvas = barracuda:new_canvas()
+symbo:append_ga(canvas)
+
+local drv = barracuda:get_driver()
+drv:ga_to_hbox(canvas, "mybox")
+}
+\vrule A\vrule\box\mybox \vrule A\vrule
+
+Test 2: two symbols, different anchor. The first symbol (more longer than the
+second one) takes the anchor parameters from the super class Barcode, while
+the second one takes anchors from itself:
+
+\directlua{
+local barcode = barracuda:get_barcode_class()
+local ok, err = barcode:set_param{ax = 1, ay = 1} % super class set up
+assert(ok, err)
+assert(barcode.ax == 1, "barcode ax is "..tostring(barcode.ax))
+
+local c128, err = barcode:enc_by_name("code128")
+assert(c128.ax == 1, "c128 ax is "..tostring(c128.ax))
+
+local s1, err = c128:from_string("12345678901234567890"); assert(s1, err)
+local s2, err = c128:from_string("0987654321", {ax = 0, ay = 0}); assert(s2, err)
+
+local s1_ax = s1:get_param("ax")
+assert(s1.ax == 1, "1 ax is "..tostring(s1.ax))
+local s2_ax = s2:get_param("ax")
+assert(s2.ax == 0, "0 ax is "..tostring(s2.ax))
+
+local canvas = barracuda:new_canvas()
+s1:append_ga(canvas)
+s2:append_ga(canvas)
+
+local drv = barracuda:get_driver()
+drv:ga_to_hbox(canvas, "mybox")
+}\box\mybox
+
+Test 3: play with the barcodes height (ydim parameter). The vertical anchor ay
+will take to super class Barcode, previously set to 1.0. So, the symbols will
+be aligned to the top:
+
+\directlua{
+local c128, err = barracuda:get_barcode_class()
+                           :enc_by_name "code128"; assert(c128, err)
+
+local s, err = c128:from_string("123456"); assert(s, err)
+local canvas = barracuda:new_canvas()
+s:append_ga(canvas)
+
+local ok, err = s:set_param("ydim", tex.sp "30mm")
+s:append_ga(canvas, tex.sp "20mm")
+
+local ok, err = s:set_param("ydim", tex.sp "60mm")
+s:append_ga(canvas, tex.sp "40mm")
+
+local drv = barracuda:get_driver()
+drv:ga_to_hbox(canvas, "mybox")
+}\box\mybox
+
+Test 4: set up vertical anchor globally to 0.0, locally to the encoder to 0.5
+and locally to 1.0:
+
+\directlua{
+local barcode = barracuda:get_barcode_class()
+% set ay globally to 0.0
+local ok, err = barcode:set_param("ay", 0); assert(ok, err)
+
+local c128, err = barcode:enc_by_name "code128"; assert(c128, err)
+local s, err = c128:from_string("ABCDEFGHI"); assert(s, err)
+
+local canvas = barracuda:new_canvas()
+local _, err = s:append_ga(canvas); assert(not err, err)
+
+% set ay to 0.5 for the encoder
+local ok, err = c128:set_param("ay", 0.5); assert(ok, err)
+local _, err = s:append_ga(canvas, tex.sp "30mm"); assert(not err, err)
+% set locally to the symbol ay to 1.0
+local ok, err = s:set_param("ay", 1)
+local _, err = s:append_ga(canvas, tex.sp "60mm"); assert(not err, err)
+
+local drv = barracuda:get_driver()
+drv:ga_to_hbox(canvas, "mybox")
+}\box\mybox
+
+Test 5: uint() costructor and save a file with PDF literal code:
+
+\directlua{
+local barcode = barracuda:get_barcode_class()
+local c128, err = barcode:enc_by_name("code128"); assert(c128, err)
+local s, e = c128:from_uint(1234567890); assert(s, e)
+local canvas = barracuda:new_canvas()
+local _, errc = s:append_ga(canvas); assert(not errc, errc)
+local drv = barracuda:get_driver()
+drv:ga_to_hbox(canvas, "mybox")
+drv:save("native", canvas, "02-05-pdfliteral")
+}\box\mybox
+
+That's all folk!

+% test for ga-canvas pdfliteral driver

+
+---ga--- is a binary format as an istruction set similar to
+a sort of assembler language that describes simple graphic
+objects like lines and rectangles.
+This file contains tests aiming to check the pdfliteral
+driver capability to render such ga streams---usually a Lua
+array.
+
+The pdfliteral driver directly inserts PDF vector graphic
+primitives within the output and should be intented as the
+"native" driver of barracuda package.
+
+The complete reference of the ---ga--- format is available
+throgh out the content of the "ga-grammar.tex" file.
+
+Please note that all dimensions are in scaled point, the
+very small \TeX{} internal unit, in fact we have that
+65536sp = 1pt.
+
+Running the source file with luatex. The typesetting engine
+executes the directlua macro, so vector graphics appear in
+the PDF output file.

+Let's start drawing an horizontal line 100pt long:
+\directlua{

+or two different parallel lines 24pt long:
+\directlua{

+   driver:ga_to_hbox(ga, [[mybox]])

+
+and again two horizontal lines 10pt thick, touching a corner:
+\directlua{

+
+Several vertical lines with its horizontal limits:
