+ \class QtSingleCoreApplication qtsinglecoreapplication.h
+ \brief A variant of the QtSingleApplication class for non-GUI applications.
+
+ This class is a variant of QtSingleApplication suited for use in
+ console (non-GUI) applications. It is an extension of
+ QCoreApplication (instead of QApplication). It does not require
+ the QtGui library.
+
+ The API and usage is identical to QtSingleApplication, except that
+ functions relating to the "activation window" are not present, for
+ obvious reasons. Please refer to the QtSingleApplication
+ documentation for explanation of the usage.
+
+ A QtSingleCoreApplication instance can communicate to a
+ QtSingleApplication instance if they share the same application
+ id. Hence, this class can be used to create a light-weight
+ command-line tool that sends commands to a GUI application.
