# Check black compatibility and check for formatter instabilities and other
# errors.
#
# This script will first clone a diverse set of (mostly) black formatted
# repositories with fixed revisions to target/progress_projects. Each project
# gets formatted (without modifying the files on disk) to check how
# similar our style is to black. It also catches common issues such as
# unstable formatting, internal formatter errors and printing invalid syntax.
#
# The pinned revisions are the latest of this writing, update freely.
