This service enables quick generation of new val with specified [jsr](https://jsr.io) package.

Package authors can provide custom examples by setting either:

- `valtownExample` property of [`jsr.json`](https://jsr.io/docs/package-configuration)/[`deno.json`](https://docs.deno.com/runtime/manual/getting_started/configuration_file) to contain example js/ts code

- `valtownExampleFilename` property of [`jsr.json`](https://jsr.io/docs/package-configuration)/[`deno.json`](https://docs.deno.com/runtime/manual/getting_started/configuration_file) to point to the file with example js/ts code
