Composer & Swagger CodeGen

For PHP generation set gitUserId, gitRepoId and artifactVersion configs and, just add a

{
    type: "path",
    url: "path/to/gen/code"
}

repository to your composer.json and et voilá:
$ composer require [gitUserId]/[gitRepoId]

Wow!

(Do not forget artifactVersion, without that Composer won't find your package!)
