\title The Feature Definition File
The file \c src/tools/qfeatures.h includes the file \c
src/tools/qconfig.h. By modifying \c qconfig.h, you can define a
subset of the full Qt functionality that you wish to have available
on your installation.
Note that such modification is only supported on Qt/Embedded
platforms, where reducing the size of Qt is
important and the application-set is often fixed.
The \c config.h definition file simply defines macros to disable
features. Some features are dependent on other features and these
dependencies are expressed in \c qfeatures.h.
The available options are:
\table
