multi-diff

analyzes multiple yaml files and prints out common sub-trees:

$ cat test/fixtures/simple/first.yml
common_high_level:
  common_key: common
  shared_a: shared_a
  different_value:
    nested: value
  first: first

different_high_level: first
$ cat test/fixtures/simple/second.yml
common_high_level:
  common_key: common
  shared_a: shared_a
  shared_b:
    key: value
  different_value: second
  second: second

different_high_level: second
$ cat test/fixtures/simple/third.yml
common_high_level:
  common_key: common
  different_value:
    nested: value
  shared_b:
