Uniqueness of Rev. Hex Id.s

[Pietro Moras]

I
read that in a Revision identifier, such as:  “3:1ff43bfdd8a2”,
the integer No. is Working Directory unique, whereas the hexadecimal
Identifier is global unique, that is unique for all cloned copies.
Fine. Any idea what is the mathematical algorithm used to
generate such global unique codes within distinct clones of a
versioned Project? Thanks.
