+  - If the provided package name does not result in a valid PR link, it raises an excepion.
+  - If the package name discovered in the `composer.json` does not result in a valid PR link, it then
+  - Probes the git remotes to find the first that results in a valid package link.
+  In each case, it performs a `HEAD` request on the generated link to determine if it is
+  valid, following redirects as encountered.
