36<p> By modifying the configured <tt>qconfig.h</tt> file from src/tools, you
37can define a subset of the full Qt functionality that you wish to
38be available in your installation. The -qconfig option to
39configure is used to select the configuration.
40<p> Note that such modification is only supported on Qt/Embedded
41platforms, where reducing the size of Qt is
42important and the application set is often fixed.
43<p> The <tt>qconfig.h</tt> definition file simply defines macros to disable
44features. Some features are dependent on other features and these
45dependencies are expressed in <tt>qfeatures.h</tt>.
46<p> The available options are:
