+  <tmdoc-title|The <abbr|Dr.> Geo system>
+
+  <hlink|<name|<abbr|Dr.> Geo>|http://www.ofset.org/drgeo> is a <name|Gnome>
+  free software created both for the interactive study of Euclidean geometry
+  and for a mild introduction to <name|Guile>/<name|Scheme> programming.
+
+  Using <name|<abbr|Dr.> Geo>, you can draw many classical geometric
+  contructions and explore their propperties either from the metric point of
+  view (measuring angles and length) or from the transformation one (via
+  plane trasformations). Each <name|<abbr|Dr.> Geo> figure comes with a logic
+  tree which shows all steps towards its construction. The basic geometric
+  constructions provided by the software can be extended by the user adding
+  macro-constructions.
+
+  <name|<abbr|Dr.> Geo> also offers the possibility to learn
+  <name|Guile>/<name|Scheme> programming at a very introductory level. With
+  <name|Guile> scripts it is easy to interact with the geometric apparatus by
+  implementing, for example, several formulas. In the latest releases,
+  <name|<abbr|Dr.> Geo> has been improved on the programming side since it
+  can evaluate entire files written in <name|Scheme>. In this way the user
+  can take advantage from the typical structures of a high level language,
+  like recursive ones for example, to create new kinds of figures.
+
+  In <name|<abbr|Dr.> Geo> there are many utilities available to the teacher:
+  customization and locking of the user interface, integration in
+  <name|<abbr|Dr.> Geo> of a simple text editor, possibility to export
+  figures (<LaTeX>, <name|Postscript> and PNG), etc.
+
+  Currently, a project is in progress to have a <TeXmacs> plugin for
+  <name|<abbr|Dr.> Geo>. In this way it will be possible to use <TeXmacs> as
+  front-end interface for <name|<abbr|Dr.> Geo> and integrate directly all
+  the geometric figures into scientific documents.

+    Some hints about output
+  </expand>
+
+  Among the tools packages supported by <TeXmacs> environment here, some
+  experiences have to be kept in mind:
+
+  <\expand|enumerate-roman>
+    <item>Maxima and Yacas are the powerful softwares for symbolic
+    calculation;
+
+    <item>Gnuplot and other CAS's can used to plot the graphs in 2D, 3D and
+    scientific data plots. But the Gnuplot is the best recommended software
+    since the graph that it generates can be directly embedded into the
+    worksheet in <TeXmacs>.
+
+    <item>Also there are many powerful softwares with numerical abilities in
+    Linux world, for example: Octave, Lab, Scilab and R (check your "session
+    options" or the <TeXmacs>_INSTALL/lib exec). But Scilab owns its
+    "terminal session" which is not easily embedded into the <TeXmacs>,
+    Octave is the best choice due to its full accessibility.
+
+    <item>Output format: Postscript format is the best choice as above
+    mentioned. For the Windows user and not heard about this format, HTML
+    format may be the suitable one. But for mathematical document, it is may
+    be a bad news that directly output the HTML from <TeXmacs> is generally
+    non-satisfied. If you want to generate HTML files, <LaTeX>2html maybe
+    have some help. Consider to export <LaTeX> format from <TeXmacs> and use
+    the following latex2html command to translate <TeX> file into HTML and
+    picture files:
+
+    <\code>
+      \<gtr\> latex2html -nonavigation -split 0 filename.tex
+    </code>
+
+    if you want only one HTML file with picture files without navigation
+    icons. Suppose that there are plenty of pictures generated by CAS's in
+    your <TeXmacs> file, some modifications have to be made by your hand. The
+    reason is that no PS Tricks implement yet in latex2html and this is just
+    the <TeX> package used by <TeXmacs> to make in-line Postscript graphs.
+    First capture the pictures by picture capture program, e.g. ksnapshot or
+    GIMP, by CAS's in another xterm and save it as eps format. Then edit the
+    <LaTeX> file, removing all lines including "cat code
+    <with|mode|math|\<cdots\>>" in presume part and adding the eps graphs as
+    follows : \ 
+
+    <\verbatim>
+      <with|mode|math|\<backslash\>>document[12pt]{article}
+
+      <with|mode|math|\<backslash\>>package[dvips]{graphics}
+
+      \ \ \ <with|mode|math|\<cdots\>>
+
+      % remove all the line beginning with "catcode"
+
+      \ \ \ <with|mode|math|\<cdots\>>\ 
+
+      <with|mode|math|\<backslash\>>begin{document}
+
+      \ \ \ <with|mode|math|\<cdots\>>
+
+      <with|mode|math|\<backslash\>>begin{center}
+
+      \ \ <with|mode|math|\<backslash\>>resizebox{150mm}{!}{<with|mode|math|\<backslash\>>includegraphics{picture.eps}}
+
+      <with|mode|math|\<backslash\>>end{center}
+
+      \ \ \ <with|mode|math|\<cdots\>>
+
+      <with|mode|math|\<backslash\>>end{document}
+    </verbatim>
+
+    Mainly, add the graphics package and use
+    <with|mode|math|\<backslash\>>include graphics{} to put the graph. And
+    use above latex2html commands to translate the contents. The directory
+    named by its filename will be created with HTML file, and png files.
+  </expand>
+
+  Of course, you can export the worksheet from <TeXmacs> into <LaTeX> format
+  and remake the file by <TeX> system, for example: te<TeX> or Mik<TeX>.
+  Don't forget to put TeXmacs.sty in the search tree of <TeX> and execute
+  <with|color|red|texhash>. This file can be found in the diretory of
+  $<TeXmacs><with|mode|math|\<backslash\>misc\<backslash\>latex.> Then it
+  will be no problem to <with|color|red|<LaTeX>> this tex file into
+  PostScript or PDF format.
+
+  If you are interested in <TeXmacs> and CAS, more tm files can be found at:

+
+    <item>Short development cycle: <name|gTybalt> can interpret C++ and

+  who can write extensions to the editor, without going into the C++ code of
+  <TeXmacs>. In the future, we also wish to implement a port to
+  <name|Guile-gtk>. This extension of <name|Guile> implements a graphical

+
+<\body>
+  <doc-data|<doc-title|<TeXmacs>--maxima interface>>
+
+  In this tutorial, we shall discuss how to use the free Computer Algebra
+  System (CAS) maxima from <TeXmacs>. It should be valid for <TeXmacs>-1.0.5
+  and maxima-5.9.2.
+
+  Let's start <TeXmacs>. We shall use the package <tmpackage|varsession>:
+
+  <postscript|c0.png|*5/8|*5/8||||>
+
+  This is not strictly necessary, but interactive sessions look nicer with
+  it. We shall also use <menu|Automatically close brackets>:
+
+  <postscript|c1.png|*5/8|*5/8||||>
+
+  Now we shall start one of the versions of maxima installed:
+
+  <postscript|c2.png|*5/8|*5/8||||>
+
+  Also we shall tick <menu|Mathematical input>:
+
+  <postscript|c3.png|*5/8|*5/8||||>
+
+  If you click the icon looking like ``?'' on the toolbar, <TeXmacs> will
+  show the maxima manual:
+
+  <postscript|c4.png|*5/8|*5/8||||>
+
+  It is convenient to clone the window:
+
+  <postscript|c5.png|*5/8|*5/8||||>
+
+  Then, in one of the windows you return to the buffer which contains the
+  maxima session (in this case, this buffer is called <menu|no name>):
+
+  <postscript|c6.png|*5/8|*5/8||||>
+
+  In the other window, you can read the manual. Blue texts are hyperlink;
+  clicking them displays the corresponding sections of the manual.
+
+  Everything is ready for doing calculations. Usual methematical notations
+  can be used for input expressions to a large extent. Don't forget to use
+  <key|*> for multiplication; it is not visible, just produces a little
+  space. Powers are produced using the toolbar or <key|^>; fractions -- by
+  the toolbar or <shortcut|(make-fraction)>; square roots -- by the toolbar or <shortcut|(make-sqrt)>;
+  large (automatically resizable) brackets -- by <shortcut|(make-bracket-open "(" ")" #t)> (note that with
+  our settings this produces both the opening bracket and the closing one,
+  and the cursor is left between them). You can use greek letters. For
+  example, <with|mode|math|\<alpha\>> can be produced via the toolbar, by
+  <key|H-a> (see help for the meaning of the modifier hyper), or by <key|a
+  tab>. <with|mode|math|\<Gamma\>> means the
+  <with|mode|math|\<Gamma\>>-function; <with|mode|math|\<pi\>> means ... what
+  would you think? ... <with|mode|math|\<pi\>>; <with|mode|math|\<gamma\>>
+  means the Euler constant; <with|mode|math|\<zeta\>> means the Riemann
+  <with|mode|math|\<zeta\>>-function.
+
+  <postscript|c7.png|*5/8|*5/8||||>
+
+  The integral sign is produced via the toolbar or by <key|S-F5 I>. If it has
+  limits, it means a definite integral, otherwise indefinite. Then you write
+  your integrand, then a space, the differential sign (produced by <key|d tab
+  tab>), a space, and your integration variable. The form of the result often
+  depends on parameters; in such cases, maxima asks questions. If you don't
+  want such interactive queries, you can provide the relevant information
+  beforehand.
+
+  <postscript|c8.png|*5/8|*5/8||||>
+
+  You can select some (part of) an output field with the mouse:
+
+  <postscript|c9.png|*5/8|*5/8||||>
+
+  Then click on an input line, and click with the middle mouse button. The
+  selected expression is inserted. You can edit it and execute.
+
+  <postscript|c10.png|*5/8|*5/8||||>
+
+  It is also possible to go to an earlier input line, edit it and press
+  <key|enter>. The old output below this line will be replaced by the new
+  one. This is very useful during the first stage of your work, when you
+  investigate various possible approaches. Using this method too often leads
+  to a spaghetti-like set of input and output lines, which is difficult to
+  understand; it is even difficult to reproduce your calculation later.
+
+  Here are some definite integrals. The base of natural logarithms
+  <with|mode|math|\<mathe\>> is produced via the toolbar or by <key|e tab
+  tab>, and the infinity symbol -- via the toolbar or by <key|@ @>.
+
+  <postscript|c11.png|*5/8|*5/8||||>
+
+  Sums are similar to integrals. In addition to sums with a lower limit and
+  an upper one, maxima understands sums with a lower limit like
+  <with|mode|math|n\<in\>[a,b,c]>, where the symbol <with|mode|math|\<in\>>
+  is produced by <key|\\ i n enter>. Products are also similar. Binomial
+  coefficients are produced by <key|\\ b i n o m enter>. They look like
+  matrices, but differ from them! Therefore, don't try to create them via the
+  toolbar menu for matrices and other kinds of tables.
+
+  <postscript|c12.png|*5/8|*5/8||||>
+
+  Note a subtle point: the integral sign (or the sum or product sign) is
+  considered as a kind of an ``opening bracket'', and there is the
+  corresponding ``closing bracket'', which is invisible, but it shows where
+  your integral ends. You can see it in the <menu|Document|View|Edit source
+  tree> mode as <explain-macro|big\|.>. With out setting of
+  <menu|Edit|Preferences|Keyboard|Automatically close brackets>, it is
+  automatically produced after the integral sign when you input it; if you
+  don't use this mode, you can produce it by <key|\\ b i g tab . enter>.
+
+  <postscript|c13.png|*5/8|*5/8||||>
+
+  Maxima understands matrices and determinants. They are produced via the
+  toolbar. New columns and rows are inserted by <shortcut|(structured-insert-right)>, <shortcut|(structured-insert-left)>,
+  <shortcut|(structured-insert-down)>, <shortcut|(structured-insert-up)>. The imaginary unit <with|mode|math|\<mathi\>> is
+  produced via the toolbar or by <key|i tab tab>.
+
+  <postscript|c14.png|*5/8|*5/8||||>
+
+  <postscript|c15.png|*5/8|*5/8||||>
+
+  You can inserted some text explaining an input line. To this end, placing
+  the cursor on this input line, select <menu|Insert text field> from the
+  toolbar menu:
+
+  <postscript|c16.png|*5/8|*5/8||||>
+
+  Naturally, this explanation text can be as long as you need, and it can
+  contain mathematical formulae.
+
+  <postscript|c17.png|*5/8|*5/8||||>
+
+  And here is a determinant.
+
+  <postscript|c18.png|*5/8|*5/8||||>
+
+  <postscript|c19.png|*5/8|*5/8||||>
+
+  Maxima can solve equations and systems of equations. It returns the list of
+  solutions.
+
+  <postscript|c20.png|*5/8|*5/8||||>
+
+  Here we define and plot the function <with|mode|math|f(x,y)=<frac|sin(r)|r>>
+  where <with|mode|math|r=<sqrt|x<rsup|2>+y<rsup|2>>>.
+
+  <postscript|c21.png|*5/8|*5/8||||>
+
+  The plot appears in a separate gnuplot window:
+
+  <postscript|c22.png|*5/8|*5/8||||>
+
+  Here we define a recursive function and trace its execution.
+
+  <postscript|c23.png|*5/8|*5/8||||>
+
+  You can create a ``sub-session'' within the maxima session. With the cursor
+  on an input line, select <menu|Fold input field> from the toolbar menu:
+
+  <postscript|c24.png|*5/8|*5/8||||>
+
+  A sub-session appears; you can edit its title:
+
+  <postscript|c25.png|*5/8|*5/8||||>
+
+  You can work within this sub-session; it has its own current input line.
+
+  <postscript|c26.png|*5/8|*5/8||||>
+
+  If you dowble-click on the left bar of the sub-session, it gets folded:
+
+  <postscript|c27.png|*5/8|*5/8||||>
+
+  Now only its title is visible. This is convenient for long sub-calculations
+  of your project: you can fold them all, and see only the skeleton of your
+  calculation. Sub-sessions can be nested. You can unfold them by
+  double-clicking once more.
+
+  Finally, we quit maxima:
+
+  <postscript|c28.png|*5/8|*5/8||||>
+
+  If you give a presentation, it is convenient to select <menu|Remove all
+  output fields> from the toolbar menu:\ 
+
+  <postscript|c29.png|*5/8|*5/8||||>
+
+  All output lines disappear.
+
+  <postscript|c30.png|*5/8|*5/8||||>
+
+  It suffices to press <key|enter> on an input line, and maxima will be
+  re-started. The results will be produced in the presence of your audience,
+  just by pressing <key|enter> many times.
+
+  <postscript|c31.png|*5/8|*5/8||||>
+
+  Of course, you can save your work as a .tm file. Next time you start
+  <TeXmacs> to edit this file, just press <key|enter> at the first input line
+  to re-start maxima.

+
+  GNU <name|Octave> is a high-level language, primarily intended for
+  numerical computations. It provides a convenient command line interface for
+  solving linear and nonlinear problems numerically, and for performing other
+  numerical experiments using a language that is mostly compatible with
+  <name|Matlab>. It may also be used as a batch-oriented language.
+
+  <name|Octave> has extensive tools for solving common numerical linear
+  algebra problems, finding the roots of nonlinear equations, integrating
+  ordinary functions, manipulating polynomials, and integrating ordinary
+  differential and differential-algebraic equations. It is easily extensible
+  and customizable via user-defined functions written in <name|Octave>'s own
+  language, or using dynamically loaded modules written in C++, C, Fortran,
+  or other languages.
+
+  A first experimental interface between <TeXmacs> and GNU <name|Octave> has
+  been written by <name|Michael Graffam>. Unfortunately, we get little help
+  from the main <name|Octave> developers for the improvement of the interface
+  and the integration of patches into the mainline of <name|Octave>. So, if
+  you like the idea of using <name|Octave> from inside <TeXmacs>, then please
+  help advertising it.

+
+  <name|Qcl> è un linguaggio di programmazione di alto livello e indipendente
+  dall'architettura per i computer quantistici, con una sintassi derivata dai
+  linguaggi procedurali classici come il <name|C> o il <name|Pascal>. Questo
+  permette la completa implementazione e la simulazione di algoritmi
+  quantistici (includendo componenti classiche) in un formalismo consistente.
+  L'interfaccia di <TeXmacs> è utile soprattutto per visualizzare in modo
+  leggibile gli stati quantici. Per maggiori informazioni si veda
+
+  <\verbatim>
+    \ \ \ \ http://tph.tuwien.ac.at/~oemer/qcl.html
+  </verbatim>
+
+  Come consiglio, gli utilizzatori farebbero meglio ad installare la versione
+  binaria più recente, ora vi è la 0.5, poiché è difficile compilare dai
+  codici sorgenti. Inoltre, se si installa <name|Qcl> dalla versione binaria,
+  ci si assicuri che tutta la directory di libreria, <verbatim|lib>, sia
+  sotto la directory in cui sono posti i file binari <verbatim|qcl>.

+    Utilizzare le sessioni di GNU R in <TeXmacs>
+  </expand>
+
+  GNU <name|R> è un insieme integrato di strumenti software per la
+  manipolazione dei dati e la visualizzazione grafica. Molte persone
+  utilizzano R come un sistema statistico. Ma gli sviluppatori preferiscono
+  pensarlo come uno strumento in cui sono stati implementate molte tecniche
+  statistiche classiche e moderne. Si può scaricare <name|R> da
+
+  <\verbatim>
+    \ \ \ \ http://www.r-project.org
+  </verbatim>
+
+  Per poter lanciare una sessione di <name|R> in <TeXmacs>, si utilizza
+  <apply|menu|Insert|Session|R>. La funzione <verbatim|v()>può essere
+  utilizzata per includere il contenuto delle finestre grafiche di <name|R>
+  nel proprio foglio di lavoro.
+
+  <\session|r|default>
+    <\output>
+      \<gtr\> Welcome to the TeXmacs interface to R.
+
+      To put the current graph in the TeXmacs buffer as an eps use v().
+
+      The functions plotv(), linesv(), and pointsv() are provided as a
+      convenience.
+
+      They do the regular function, and then insert the graph.
+
+      \;
+
+      To change the size of the graph that is inserted to TeXmacs,just adjust
+      the size of the X11 window.

+  <expand|tmdoc-title|The GNU R system>
+
+  <hlink|R|http://www.r-project.org/> is a language and environment for
+  statistical computing and graphics. It is a GNU project which is similar to
+  the S language and environment which was developed at Bell Laboratories by
+  J<name|ohn Chambers> and colleagues. R can be considered as a different
+  implementation of S. There are some important differences, but much code
+  written for S runs unaltered under R.
+
+  R provides a wide variety of statistical (linear and nonlinear modelling,
+  classical statistical tests, time-series analysis, classification,
+  clustering, ...) and graphical techniques, and is highly extensible. The S
+  language is often the vehicle of choice for research in statistical
+  methodology, and R provides an Open Source route to participation in that
+  activity.
+
+  A first experimental interface with <TeXmacs> has been written by
+  <name|Michael Lackmann>. This allows you to use R interactively inside
+  <TeXmacs> and to easily include tables and the high quality plots from R
+  into your scientific papers.

+  <expand|tmdoc-title|The <TeX>/<LaTeX> system>
+
+  <TeX> (= tau epsilon chi, and pronounced as "tecch") is a computer language
+  for use in mathematical typesetting, developed by <abbr|D.E.> <name|Knuth>
+  from the late 1970s until the late 1980s. The main aim was to provide
+  output with a typesetting quality that you would expect in nicely printed
+  books. In the meantime, D.E. <name|Knuth> also developed <name|Metafont>, a
+  tool to automatically generate nice looking (mathematical) character fonts.
+  In the 1980s and 1990s <TeX> has been extended by many people, given rise
+  for instance to <LaTeX>, <name|Ams><TeX> and so on. Current <TeX>
+  distributions usually contain all these different programs.
+
+  In order to use <TeXmacs>, it is assumed that you have installed a <TeX>
+  system on your system, although <TeXmacs> really only uses the
+  <name|Metafont> program to generate its fonts. At the moment, <TeXmacs>
+  also needs the <name|Bib<TeX>> program for generating bibliographies.
