[ -- ] [ input
command links inline elements to DFN elements with the same content.
It adds ID attributes where necessary. If the content of a DFN or
other element isn't suitable, the TITLE attribute may be used to
provide the term to use for comparisons.
Here is an example:
<p>A <dfn>b-box</dfn> is defined to be...
<p>For every b there is a <em>b-box</em>...
The output of
will be similar to this:
<p>A <dfn id="b-box">b-box</dfn> is defined to be...
<p>For every b there is a <a href="#b-box"><em>b-box</em></a>...
The following options are supported:
Use XML conventions: empty elements are written with a slash at the
end: <IMG />
- -b base
Sets the prefix for the generated URLs. By default
is empty, which generates URLs like "#b-box" above. If
is set to, e.g., "http://xyz/", the URLs will look like

to read terms from a database file before looking for them in the
document and afterwards store the terms that were found in the same
file. DFN element in the document override terms found in
to be run multiple times on different files, to make the files refer
to each other. It may be necessary to run the commands twice, to
resolve all cross-references.
Try to use language-specific information to match instances to their
definitions. Currently, only English is supported and the only rules
applied are to search without a final "s" ("trees" matches "tree"),
without a final "es" ("bosses" matches "boss") and with a "y"
replacing a final "ies" ("bounties" matches "bounty").

The following operands are supported:
The name of an HTML file. If absent, standard input is read instead.
The special name "-" also indicates standard input. The
may be an URL.
The file to write to. If absent, standard output is used. This may
be a URL.
The following exit values are returned:

An error occurred in the parsing of the HTML file.
will try to correct the error and produce output anyway.
The error recovery for incorrect HTML is primitive.
The program generates ID attributes, but doesn't generate <a name=...>
tags, so the links only work in browsers that recognize ID attributes.
The rules for matching English plurals are primitif. No dictionary is
used. E.g., "bees" will be considered a plural of "be".
There is currently no way to set the default language for a document
for when the root element has no "lang" or "xml:lang" attribute.
tries first to generate "readable" ID attributes, by forming the ID
out of the letters and digits found in the content of the element and
falls back to generating arbitrary IDs if it doesn't find
enough. However, the algorithm in this version is primitive and only
gives reasonable results for ASCII letters and digits.
