# This script downloads information about changes landed in the Fuchsia tree
# and computes the dates at which those changes receive Code, API, and
# Testability reviews. It produces four fields into a CSV file:
# * Change-ID
# * Time at which the change first received Code-Review+2 and API-Review+1.
# If a change never received API-Review+1, the time the change first received
# Code-Review+2 is used. This is an approximation of when the change is first
# eligible to receive a Testability Review.
# * Time at which the change first received a Testability-Review vote, either
# +1 or -1.
# * Email of the first reviewer to set Testability-Review
# It caches information from Gerrit into //local/change_id_cache/.
