 `hype` wraps `hono` with useful features for fast prototyping:
 
 - HTTP logging to the console (disable with `NO_HTTP_LOG` env variable)
+- Auto-port selection in dev mode: if the port is busy, tries the next one (disable with `NO_AUTOPORT` env variable)
 - Static files served from `pub/`
 - Page-based routing to `.tsx` files that export a `JSX` function in `./src/pages`
 - Transpile `.ts` files in `src/client/blah.ts` via `website.com/client/blah.ts`
