// A tester designed to work on the Lempel-Ziv-Oberhumer
// compression/decompression algorithm.  Note that we've chosen to use
// the LZO1f variant--according to the results provided by Oberhumer,
// that variant does best with short compression sources.



// Prevent multiple inclusion by surrounding the header file with
