Hello

A simple web server with some configuration knobs, for use in practicing configuration.

The server emits a page that contains its version, followed by a greeting, followed by the value specified in request path.

A request path of /quit exits the server.

Configuration Knobs

• Integer port flag, default 8080.

• A hard-coded version const set to zero, change it to make ambiguous differences between binaries.

• Boolean flag enableRiskyFeature, default false. If enabled, the greeting is italicized.

• Environment variable ALT_GREETING. If set, the value overrides the default greeting Hello.
