The HTML converter necessarily uses a post-processor, which re-parses the
output of the <code>yodl</code> program. The post-processor is necessary for a variety
of reasons: the HTML output is split into several files, a table of contents
is created, labels and references to labels are resolved.

The post-processor is a program <code>yodl2html-post</code> and is automatically
activated when the shellscript <code>yodl2html</code> is used. I therefore strongly urge
you to convert Yodl documents to HTML using this script.

The usage of the post-processor has one important drawback. The <code>yodl</code>
program <em>sec</em> places tags for the post-processor in its output. The
post-processor takes actions according to the tags.

The tags start with <code>.yodltagstart.</code> and end with <code>.yodltagend.</code> (though 
in upper case, guess why I typed them here in lowercase?).  Therefore, you
<strong>cannot</strong> put these strings in a Yodl document that should be converted to
HTML. The tags would however be harmless in other output formats. (If this 
setup that uses tags proves to be a problem, I'll implement a way around it. 
Besides, the tags can be configured in the top-level <code>Makefile</code> when 
installiong the Yodl package.)
