ARROW-1 - Initial Arrow Code Commit
ARROW-2 - Post Simple Website
ARROW-3 - This patch includes a WIP draft specification document for the physical Arrow memory layout produced over a series of discussions amongst the to-be Arrow committers during late 2015. There are also a few small PNG diagrams that illustrate some of the Arrow layout concepts.
