<!--l. 1226--><p class="noindent"><a 
   name="features"></a>The translation of a LaTeX source file into HTML consists of loading the style package <span 
class="cmtt-10">tex4ht.sty </span>into the
source file, choosing the desirable options for the translation, compiling the source into <span 
class="cmtt-10">dvi </span>code with
the native LaTeX engine, and postprocessing the outcome with the <span 
class="cmtt-10">tex4ht </span>and <span 
class="cmtt-10">t4ht </span>programs (see
<a

</p><!--l. 1235--><p class="indent">    <a

transtional 4.0 code. </dd><dt><span

<!--l. 1435--><p class="noindent"><a

</p><!--l. 1440--><p class="indent">    TeX4ht doesn&#8217;t offer a built-in parser to verify the correctness of the outcome. However, external validator(s)

</p>
    <h3 class="SubSectionHead"><a 
   name="QQ1-3-9"></a>Recommendations</h3>
<!--l. 1451--><p class="noindent">Most applications might require the knowledge of just a few additional simple features of TeX4ht, if any. Hence, it is
strongly advised to check the output obtained from the default configuration, before trying to work with other
settings.
</p><!--l. 1456--><p class="indent">    The remainder of this document provides much more than that, with an eye directed toward users that want to
customize their outcome. Therefore, the reader is encouraged to skim the information provided below for acquiring
a general understanding of the system, leaving the tedious learning of the details to when the need
arises.
</p><!--l. 1463--><p class="indent">    To keep with the spirit of LaTeX and hypertext, in which style is assumed to be separated from content, the
users are encouraged to avoid inserting TeX4ht code into their source files. Instead, they should place their
modifications, to the default settings, within private configuration files to be loaded by htlatex-like
commands.

<!--l. 3874--><p class="noindent"><a 
   name="index3-24001"></a>Literate programming is a discipline that promotes the writing of programs the way one explains them to human
beings. ProTeX is a literate programming system fully implemented in terms of TeX, and it is compatible with
LaTeX and other TeX-base systems. TeX4ht, and ProTeX itself, are examples of applications written in
ProTeX.
