package genswagger

import "github.com/goadesign/goa/goagen/gen_swagger"

Package genswagger provides a generator for the JSON swagger controller. The swagger controller responds to GET /swagger requests with the API JSON Hyper-swagger. This JSON swagger can be used to generate API documentation, ruby and Go API clients. See the blog post (https://blog.heroku.com/archives/2014/1/8/json_swagger_for_heroku_platform_api) describing how Heroku leverages the JSON Hyper-swagger standard (http://json-swagger.org/latest/json-swagger-hypermedia.html) for more information.
