---------------------------------------
Hi Owen,
- Thanks for the help/great comments.
- I am trying to convince Hong to have vint stuff decoupled to a
sepearate JIRA and make it easier for TFile to get through. We can push
for it a bit more inside this JIRA, later we could give some grounds or
make bargaining chip out of it.
- Any action item for "# number of columns included in header"?
We don't have such a thing now ;)
Meta Blocks which contain Metadata show up later in the file. Header
is just a Magic Number ...
Thanks
Amir
