Coming from q?

Most familiar q concepts carry over. Begin with the differences, particularly file-format inference, storage support and launch options. The inherited q reference describes q; it is not a guarantee that every feature is implemented in PeachQ. The dedicated PeachQ section explains additions, intentional differences and known limits.
