 synopsis:       Dockerfile parser, pretty-printer and embedded DSL
 description:    All functions for parsing and pretty-printing Dockerfiles are exported through @Language.Docker@. For more fine-grained operations look for specific modules that implement a certain functionality.
                 See the <https://github.com/hadolint/language-docker GitHub project> for the source-code and examples.
