Recursively map a YAML value with a Ruby snippet.

Also included in the aggregate gem:

gem install dorian

yaml-deep-map [file ...] "ruby code"

Run yaml-deep-map -h for generated option details and yaml-deep-map -v for the installed version.

• Mutate or replace it in the snippet; the final YAML is printed.
