Hi Andy,

Thanks! I never looked into this part of docs before so I naively expected that 
checksums can always be obtained / recalculated on demand. I guess I'll live 
without them for now :)

Out of curiosity, how do you store such meta information? It seems problematic 
for file-systems like hadoop?
