6# Convenience script for running run_on_app.py finding minimum memory need for
7# compiling a given app back in time. This utilizes the prebuilt r8 jars on
8# cloud storage.
9# The script find all commits that exists on cloud storage in the given range.
10# It will then run the oldest and newest such commit, and gradually fill in
11# the commits in between.
