/**
* This doclet generates HTML-formatted documentation for the specified modules,
* packages and types.
*
* <h2><a id="user-defined-taglets">User-Defined Taglets</a></h2>
*
* The standard doclet supports user-defined {@link Taglet taglets},
* which can be used to generate customized output for user-defined tags
* in documentation comments.
*
* Taglets invoked by the standard doclet must return strings from
* {@link Taglet#toString(List,Element) Taglet.toString} as follows:
*
* <dl>
* <dt> <i>Inline Tags</i>
* <dd> The returned string must be
* <a href="https://www.w3.org/TR/html52/dom.html#flow-content">flow content</a>,
* or any valid fragment of HTML code that may appear in the body of a document.
* There may be additional constraints, depending on how the tag is to be
* used in a documentation comment: for example, if the tag may be used
* within an inline element such as {@code <b>} or {@code <i>}, the taglet
* must not return a string containing block tags, like {@code <h3>} or
* {@code <p>}.
* <dt> <i>Block Tags</i>
* <dd> The returned string must be suitable content for a definition list,
* or {@code <dl>} element. It will typically be a series of pairs
* of {@code <dt>} and {@code <dd>} elements.
* </dl>
*
