        <title>Description</title>
        <para>
            <function>listfiles</function> can be used to list the files which match
            the patterns given by one of the paths entries.
            Patterns are given to the Unix <command>ls</command> or to the Windows
            <command>dir</command> commands in order to get information about files.
            Thus in order to write portable Scilab script valid wildcard patterns
            for both OS are to be given. Note that pathname conversion is
            performed and for example <literal>SCI/core/macros/*.sci</literal> is a valid
            pattern for both Unix and Windows.
        </para>
        <para>
            If <varname>flag</varname> is true the pathnames given by
            <varname>paths</varname> are converted according to the <code>getos() == 'Windows'</code>
            value (see also <link linkend="pathconvert">pathconvert</link>).
            Moreover, if <varname>flagexpand</varname> is true leading strings like
            <literal>SCIHOME</literal>, <literal>SCI</literal> or
            <literal>~</literal> are expanded using environment variables.
        </para>
        <para>
            If the input argument <varname>paths</varname> is the name of a directory, the returned <varname>files</varname>
            are the names relative to that directory.
        </para>
        <para>
            If the input argument <varname>paths</varname> contains more than one element, or if it contains
            a pattern (e.g. <literal>"/*"</literal>, <literal>"*.c"</literal>), the returned <varname>files</varname> are the absolute paths (i.e.
            file name prepended with the name of the directory).
