# Used to find dependencies not strictly set
# Use-case:
#   - We used to have our own package_constraints.txt to handle upstream HA-core dependencies (but never amended it)
#   - We have a couple of local 'commit' and 'test' requirements in common (e.g. we let HA-core prevail)
#   - For everything *not* in use by HA-core we still would want dependabot to kick in appropriately
#   - This script will exit with error if it finds 'unversioned' dependencies (as such should be part of our CI)
