+// This class fixes the sizing bugs in MFC that calculates the
+// size of toolbars incorrectly for modern toobars (comctl32 version >= 4.71)
+// It also contains a number of wrappers for function that CToolBar doesn't
+// have (so you don't have to use GetToolBarCtrl).
+//
+// Generally, you should use CFlatToolBar instead of CFixMFCToolBar (even
+// if you're not using the flat style), but you can use CFixMFCToolBar if
+// all you want is the sizing fix for MFC tooblars.
