# == Usage
#
# Active Record supports optimistic locking if the +lock_version+ field is present. Each update to the
# record increments the +lock_version+ column and the locking facilities ensure that records instantiated twice
# record increments the integer column +lock_version+ and the locking facilities ensure that records instantiated twice
# will let the last one saved raise a +StaleObjectError+ if the first was also updated. Example:
#
# p1 = Person.find(1)
