#!/usr/bin/env python3
#
# Requirements:
# - Install dependencies: `pip3 install pybuildkite requests`
# - Get a Buildkite API token with read_agents and write_agents permissions
#   and put it into the BUILDKITE_TOKEN environment variable.
# - Optional: Modify "FILTER" below to restart different groups of agents.
#   For example, you can put "windows" there to restart Windows agents.
