labels.yml

# Define labels, description, color
# Support ‘previous’ for label changes over time / changes in ownership
# Apply/remove label based on condition and/or slash command
# Apply labels based on file path
# Treat labels as namespaced based on “path” (slash separated) 


labels:
- name: foo
  color: 00ff00
  description: foo stuff
  previously:
  - name: bar
- name: baz
  color: 0000ff
  description: baz stuff


# each rule should be evaluated to determine what the labels should look like
# and ONLY apply them if there is a difference. This will prevent removal of 
# labels in between steps (e.g. ensure there is only one namespaced one present)
