In the README, the option is listed as:
-e|--edge-attributes: Sets attributes applied to all edges.
-e|--dirty-attributes: Sets attributes applied to dirty nodes only.
The dirty attributes option should be '-d|--dirty-attributes' to match the actual flag usage.
Quick fix:
-e|--edge-attributes: Sets attributes applied to all edges.
-d|--dirty-attributes: Sets attributes applied to dirty nodes only.
Fantastic tooling. Great work!
