+Qbs
+---
+
+Generates Qbs project files.
+
+Project files for Qbs will be created in the top directory and
+in every subdirectory which features a CMakeLists.txt file containing
+a PROJECT() call.  Additionally a hierarchy of makefiles is generated
+into the build tree.  The appropriate make program can build the
+project through the default make target.  A "make install" target is
+also provided.
+
+This "extra" generator may be specified as:
+
+``Qbs - MinGW Makefiles``
+ Generate with :generator:`MinGW Makefiles`.
+
+``Qbs - NMake Makefiles``
+ Generate with :generator:`NMake Makefiles`.
+
+``Qbs - Ninja``
+ Generate with :generator:`Ninja`.
+
+``Qbs - Unix Makefiles``
+ Generate with :generator:`Unix Makefiles`.

+----------------------
+
+* It is now possible to generate :generator:`Qbs` project files
+  for use with QtCreator IDE, matching make tool must be used
+  to build the project through the generated makefiles.
