Long: `Starts the 'ponzu' HTTP server for the JSON API, Admin System, or both.
The segments, separated by a comma, describe which services to start, either
'admin' (Admin System / CMS backend) or 'api' (JSON API), and, optionally,
if the server should utilize TLS encryption - served over HTTPS, which is
automatically managed using Let's Encrypt (https://letsencrypt.org)
Defaults to 'run -port=8080 admin,api' (running Admin & API on port 8080, without TLS)
Note:
Admin and API cannot run on separate processes unless you use a copy of the
database, since the first process to open it receives a lock. If you intend
to run the Admin and API on separate processes, you must call them with the
'ponzu' command independently.`,
Example: `$ ponzu run
(or)
$ ponzu run --port=8080 --https admin,api
(or)
$ ponzu run admin
