It's been a while, but IIRC, basically you create binaries of each version, then XOR them against each other to create the binary delta file. Make sure to compress the delta before storing it, or you won't realize much (if any) space savings.
To go back to a version, you just XOR a binary of the current version against each decompressed delta in succession all the way back to the version you want. Hope this helps.
