strange example

[Jonathan003]

You give this as example ocgdb -create -pgn big1.png -pgn big2.png -db :memory: -elo 2100 -o moves,moves1,discardsites

Is this a typo, or douse it makes sense to list the options moves,moves1 ?

It is correct and the example is in purpose. The database can have zero, one, or two columns for moves. In the case of having two columns, the first one must be Moves for moves in text format (human-readable), the other column could be either Moves1 or Moves2 for moves in binary formats.

Thanks for the explanation.
