204 \brief The QLibraryInfo class provides information about the Qt library.-
205-
206 Many pieces of information are established when Qt is configured and built.-
207 This class provides an abstraction for accessing that information.-
208 By using the static functions of this class, an application can obtain-
209 information about the instance of the Qt library which the application-
210 is using at run-time.-
211-
212 You can also use a \c qt.conf file to override the hard-coded paths-
213 that are compiled into the Qt library. For more information, see-
214 the \l {Using qt.conf} documentation.-
