<p>
Assume that you have a file, <span class="c013">a.tex</span>, written in L<sup>A</sup>T<sub>E</sub>X, using the
<span class="c013">article</span>, <span class="c013">book</span> or <span class="c013">report</span> style. Then,
translation
is achieved by issuing the command:
</p><pre class="verbatim"># hevea a.tex
</pre><p>Probably, you will get some warnings. If
H<span class="c015"><sup>E</sup></span>V<span class="c015"><sup>E</sup></span>A does not crash, just ignore them for the moment
(Section <a href="manual006.html#trouble">4</a> explains how to correct errors).</p><p>If everything goes fine, this will produce a new file,
<span class="c013">a.html</span>, which you can visualise through a html browser.</p><p>If you wish to experiment H<span class="c015"><sup>E</sup></span>V<span class="c015"><sup>E</sup></span>A on small L<sup>A</sup>T<sub>E</sub>X source fragments,
then launch H<span class="c015"><sup>E</sup></span>V<span class="c015"><sup>E</sup></span>A without arguments. H<span class="c015"><sup>E</sup></span>V<span class="c015"><sup>E</sup></span>A will read its
standard input and print the translation on its standard output.
For instance:
</p><pre class="verbatim"># hevea
$x \in \mathcal{E}$
^D
<span style="font-style:italic">x</span> &#X2208; <span style="color:red"><span style="font-style:italic">E</span></span>
</pre><p>Incidentally, notice that the symbol “∈” translates to the
appropriate numerical character reference and that the calligraphic
letter “<span style="font-style:italic;color:red">E</span>” renders as a red “<span class="c018">E</span>”. You can find some
more elaborate <a href="http://hevea.inria.fr/examples/index.html">examples</a> in
the on-line documentation.</p>
