<h2>Summary</h2>
<!-- XXX: Should mention other possibilities in Apache: mod_header -->
Emulate the CERN HTTPD Meta file semantics. Meta files are HTTP
headers that can be output in addition to the normal range of
headers for each file accessed. They appear rather like the
Apache .asis files, and are able to provide a crude way of
influencing the Expires: header, as well as providing other
curiosities. There are many ways to manage meta information,
this one was chosen because there is already a large number of
CERN users who can exploit this module.
<p>More information on the <a
href="http://www.w3.org/Daemon/User/Config/General.html#MetaDir">
CERN metafile semantics</a> is available.</p>

<p>Specifies the name of the directory in which Apache can find
meta information files. The directory is usually a 'hidden'
subdirectory of the directory that contains the file being
accessed. Set to "<code>.</code>" to look in the same directory
as the file.</p>

<p>Specifies the file name suffix for the file containing the
meta information. For example, the default values for the two
directives will cause a request to
<code>DOCUMENT_ROOT/somedir/index.html</code> to look in
<code>DOCUMENT_ROOT/somedir/.web/index.html.meta</code> and
will use its contents to generate additional MIME header
information.</p>
