+
+    \internal
+    \class QSystemLibrary
+
+    The purpose of this class is to load only libraries that are located in
+    well-known and trusted locations on the filesystem. It does not suffer from
+    the security problem that QLibrary has, therefore it will never search in
+    the current directory.
+
+    The search order is the same as the order in DLL Safe search mode Windows,
+    except that we don't search:
+    * The current directory
+    * The 16-bit system directory. (normally c:\windows\system)
+    * The Windows directory.  (normally c:\windows)
+
+    This means that the effective search order is:
+    1. Application path.
+    2. System libraries path.
+    3. Trying all paths inside the PATH environment variable.
+
+    Note, when onlySystemDirectory is true it will skip 1) and 3).
+
+    DLL Safe search mode is documented in the "Dynamic-Link Library Search
+    Order" document on MSDN.
+
+    Since library loading code is sometimes shared between Windows and WinCE,
+    this class can also be used on WinCE. However, its implementation just
+    calls the LoadLibrary() function. This is ok since it is documented as not
+    loading from the current directory on WinCE. This behaviour is documented
+    in the documentation for LoadLibrary for Windows CE at MSDN.
+    (http://msdn.microsoft.com/en-us/library/ms886736.aspx)
