  $tit Write html pages with a programmability extension: substitution of

      variables, conditional branching, etc.$titend

      This wims programmability extension to html does not require any

      addon or plugin at the browser side, as all the wims commands are treated

      by the wims server before sending the result to the browser, which will

      be a standard html page. <br/>

      For example, this allows you to define style macros which can be

      dynamically changed. <br/>

      And this extension can cohabit with all the current (and hopefully

      future) html standards, including java applets, javascripts, embedded

      objects,

      dhtml... This is because the wims extension follows a strict line

      discipline (i.e. a wims command must start at the first word of a line),

      while html standard is not line-oriented. <br/>

      This means that you can even embed wims extensions into javascripts,

      applets, dhtml...

  </li>

  $tit Dynamic insertions of paints, plots and TeX formatted mathematical

      formulas into html pages. $titend

      For example, you may insert the following line into your wims-extended html

      page. At the browser side, the visitor will see a TeX formatted matrix

      whose content varies with the value of the variable $emph $$matrix$emphend:

      <pre>

     $ !instex $$$$ \left( $$matrix \right) $$$$</pre>

      Moreover, this implementation of dynamic insertions makes future updates

      possible without modification at module's level. (For example when a

      better way to render mathematical formula is available, a simple

      modification at server's level will immediately let all $emph!instex

      $emphend lines take benefit of the new standard.)

  </li>

  $tit Insplot is now animated!$titend

      Exemple: the tool

      !href module=tool/geometry/animtrace.$lang&cmd=intro Tracés Animés

      .

  </li>

  $tit Direct interfaces to powerful external software packages.$titend

      For example, you may define a variable `factor' by the following line:

      <pre>

      factor=!exec pari print(factor($$number))</pre>

      Upon execution of this line, the variable $number will be replaced by

      its current value, then the software package `PARI' will be called

      with the string `print(factor(<value of $$number>))' as command to

      execute. The output of the program, with the overheads stripped, will

      be placed as the value of the variable `factor'. <br/>

      Interfaces provided in version $wims_version of wims: PARI, Maxima, MuPAD,

      Coq, Povray, gnuplot, PostgreSQL, Fly (gif drawing), CALC (by Keith Matthew).

  $tit Simple and versatile language.$titend

      The language used for wims modules is an extension of the existing and

      popular html language. This extension is designed to be simple,

      easy to use and close to natural language. Synonymes are accepted

      whenever necessary. For example, to include the content of another

      file, you don't have to remember whether the command is

      $emph include$emphend as in C, or $emph input$emphend as in TeX,

      because both are valid.

  </li>

  $tit Convenient directives for string manipulations:$titend

      replace with regular

      expression capability, extraction of a subset from a list of items,

      shuffle, evaluation of mathematical expressions, etc.

  </li>

  $tit Easy inline mathematical symbols:$titend

      simply type <span class="tt">$$m_pi</span> for $m_pi, <span class="tt">$$m_RR</span> for

      $m_RR, <span class="tt">$$m_le</span> for

      $m_le, <span class="tt">$$m_Rightarrow</span> for $m_Rightarrow, etc.

  </li>

  $tit Intelligent treatment of mathematical expressions:$titend

      built-in translation routines to allow error-tolerant expressions

      like <span class="tt">2y</span> (instead of <span class="tt">2*y</span>) or <span class="tt">(x+1)(x-1)</span>

      (instead of <span class="tt">(x+1)*(x-1)</span>), and translations of raw mathematical

      expressions into beautified html sources (<span class="tt">x^3-3*x^2+1*x-5</span>

      will become $emph

      !htmlmath x^3-3*x^2+1*x-5

      $emphend,

      etc.), or TeX sources, etc.

  </li>

  $tit Powerful random capabilities:$titend

      random permutation (shuffle), random

      record from a datafile, random filename, etc.

  </li>
