+          To accommodate this, we do our best to fit the first three version components into a single integer that increases with each release.
+          We'll bit-shift the major version to the most significant byte of a 4-byte integer.
+          We'll bit-shift the minor version to the next most significant byte.
+          We'll use the least 2 significant bytes for the build number.
+          The major version must not exceed 124 to guarantee that the overall integer never exceeds 2100000000 even with the other numbers added.
+          Other components are also limited since they must fit within the 8 or 16 bits allowed for them.
