# Note that this schema.rb definition is the authoritative source for your

# from scratch. The latter is a flawed and unsustainable approach (the more migrations
# you'll amass, the slower it'll run and the greater likelihood for issues).

# It's strongly recommended that you check this file into your version control system.
