+- `test`: Optional verbatim prefix to check that the server responds with a |
|
| 16 |
+ non-error code for the [URL][]. |
|
| 17 |
+- `<distro>`, `<variant>`, `<arch>`: Optional [glob][]s to match against the |
|
| 18 |
+ combinations `distro-url` knows about. All default to `*`, which matches |
|
| 19 |
+ everything. |
|
| 20 |
+- `<mirror>`: Optional override of the default server. Probably only useful |
|
| 21 |
+ when the above globs only match a single distro. |
