+
+   Where XX, YY and ZZ are the main version, release and patch numbers in
+   hexadecimal (using 8 bits each). All three numbers are always represented

+   appears as "0x090b07".
+
+   This 6-digit (24 bits) hexadecimal number does not show pre-release number,
+   and it is always a greater number in a more recent release. It makes
+   comparisons with greater than and less than work.
