/* This is the numeric version of the libcurl version number, meant for easier
parsing and comparions by programs. The LIBCURL_VERSION_NUM define will
always follow this syntax:
0xXXYYZZ
Where XX, YY and ZZ are the main version, release and patch numbers in
hexadecimal. All three numbers are always represented using two digits. 1.2
would appear as "0x010200" while version 9.11.7 appears as "0x090b07".
This 6-digit 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.
