 To Build
 ======
-There are OS-specific makefiles for Windows and Linux, and it is assumed you know how to build on those platforms (linux does need LD_LIBRARY_PATH so it can find the .so).

-sgio_example.d is a sample program that sends a few inquiries (std inquiry, supported VPD, USN, and MNA) and reads the first 512-byte block of a device. I would like to extend this to do something more interesting.
+Use dub to build the library. See the examples directory for sample code.
