+nt_path_converter driver utilities
+==================================
+
+[nt_path_converter] driver usage examples.
+
+[nt_path_converter]: ../../../../km/src/special/nt_path_converter
+
+Usage
+-----
+
+### convert_nt_path.exe
+
+    Usage: convert_nt_path.exe [NT_PATH...]
+
+Converts a NT-style path to a DOS-style path.
+The NT namespace can be explored using the [WinObj] utility.
+For example:
+
+    > convert_nt_path.exe \Device\HarddiskVolume2\Windows
+    C:\Windows
