-If the `-i|--info` flag is passed, six additional endpoints are registered.

-If `--page-length` is also set, these can be viewed in paginated form by appending `/n`, e.g. `/html/5` for the fifth page.

-## Refresh

-If a positive-value `refresh=<integer><unit>` query parameter is provided, the page will reload after that interval.

-This can be used to generate a sort of slideshow of files.

-Minimum accepted value is 500ms, as anything lower seems to cause inconsistent behavior. This might be changed in a future release.

-If the `--russian` flag is passed, everything functions exactly as you would expect.
