## Usage
```
distro-url [test] [<distro> [<variant> [<arch> [<mirror>]]]]
```
- `test`: Optional verbatim prefix to check that the server responds with a
non-error code for the [URL][].
- `<distro>`, `<variant>`, `<arch>`: Optional [glob][]s to match against the
combinations `distro-url` knows about. All default to `*`, which matches
everything.
- `<mirror>`: Optional override of the default server. Probably only useful
when the above globs only match a single distro.
