-/**
- * Native {@link Directory} implementation for Microsoft Windows.
- * <p>
- * Steps:
- * <ol> 
- *   <li>Compile the source code to create WindowsDirectory.dll:
- *       <blockquote>
- * c:\mingw\bin\g++ -Wall -D_JNI_IMPLEMENTATION_ -Wl,--kill-at 
- * -I"%JAVA_HOME%\include" -I"%JAVA_HOME%\include\win32" -static-libgcc 
- * -static-libstdc++ -shared WindowsDirectory.cpp -o WindowsDirectory.dll
- *       </blockquote> 
- *       For 64-bit JREs, use mingw64, with the -m64 option. 
- *   <li>Put WindowsDirectory.dll into some directory in your windows PATH
- *   <li>Open indexes with WindowsDirectory and use it.
- * </p>
