+nt_namespace driver utilities
+==================================
+
+[nt_namespace] driver usage examples.
+
+[nt_namespace]: ../../../../km/src/special/nt_namespace
+
+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
+
+[WinObj]: https://technet.microsoft.com/en-us/library/bb896657.aspx
