"""Tests building sqlite and optionally running a sql script.
Generates amalgamations, builds the sqlite shell, and optionally runs a sql
file in the sqlite shell. Designed to be passed to `git bisect run` to
determine a culprit in the sqlite repro for either an issue in the build or a
sqlite script.
Example usage:
git bisect start c12b0d5b7135 9e45bccab2b8
git bisect run ../scripts/repro_tool.py repro.sql --should_build
