     * @param out The output stream
     * @param value The integer to write
     * @throws IOException if an IO error occurs

        //Based on the .NET implementation.  See http://referencesource.microsoft.com/#mscorlib/system/io/binarywriter.cs,407

        //Write out an int 7 bits at a time.  The high bit of the byte, when on, tells reader to continue reading more bytes.
        int v = value;

        while (v >= 0x80) {
