    /*description:
    {
        It takes in charge of translating any \CodeWorker\ script to HTML.

        The source file is highlighted and keywords plus particular symbols of the
        language are linked to the online-documentation.

        Note that \samp{this.docURL} designates the URL or the directory where both the CSS
        and the    HTML documentation of \CodeWorker\ are stored. If not populated, it will resolve
        links from the directory where is the target HTML file. Don't forget to end the URL or
        directory with a trailing slash.

        If \samp{this.includeCSS} is set to a path, the styles are included into the HTML file from the path,
        rather that being linked to a file while browsing.

        To highlight any script, type:\\
        \texttt{CodeWorker \textbf{-translate} CWscript2HTML.cwp \textit{<CW-script.cw>} \textit{<CW-script.html>}}\\
        to consider that the documentation and the CSS are in the same directory, and:\\
        \texttt{CodeWorker \textbf{-translate} CWscript2HTML.cwp \textit{<CW-script.cw>} \textit{<CW-script.html>} \textbf{-insert} docURL \textit{HTML-doc-URL}}\\
        otherwise.
