"""Script for determining whether per-patch perf test votes -1.

This script assumes there exist two text files with processed BMRR results,
located at hardcoded relative paths (subdirs thereof), having several lines
of json-parseable lists of float values, corresponding to testcase results.
This script then uses jumpavg library to determine whether there was
a regression, progression or no change for each testcase.
If number of tests does not match, or there was a regression,
this script votes -1 (by exiting with code 1), otherwise it votes +1 (exit 0).
