     Ideally, QML modules have a \c{plugins.qmltypes} file in the same directory
     as the \c qmldir file. The \c qmltypes file contains a description of the
     components exported by the module's plugins and is loaded by \QC when the
     module is imported.
 
-    For Qt 4.8 and later, one or more \c qmltypes files can be listed in the
-    \c qmldir file under the \c typeinfo header. These files will be read in
-    addition to \c{plugins.qmltypes}. For more information, see
-    \l{Writing a qmltypes File}.
-
-    You can create and edit \c qmltypes files manually, but you are recommended
-    to use the \c qmlplugindump tool shipped with Qt 4.8 and later to generate
-    them automatically.
-
-    Once you have obtained \c qmlplugindump for the Qt version the QML module's
-    plugins were compiled with, run the following command to load My.Module
-    version 1.0 from \c{/import/path/my/module} including all its plugins and
-    output a description of the plugins' components to
-    \c{/import/path/my/module/plugins.qmltypes}:
-
-    \code
-    qmlplugindump -nonrelocatable My.Module 1.0 /import/path > /import/path/my/module/plugins.qmltypes

-    For Qt 4.7.x, you can compile a version of the tool called \c qmldump from
-    the sources in \c{<QtCreator>/share/qtcreator/qml/qmldump} if the Qt version
-    contains private headers.
