+            This intent serves two purposes: Swapping apps between devices and adding a
+            repo from a website (e.g. https://guardianproject.info/fdroid/repo).
+            We intercept both of these situations in the FDroid activity, and then redirect
+            to the appropriate handler (swap handling, manage repos respectively) from there.
+
+            The reason for this is that the only differentiating factor is the presence
+            of a "swap=1" in the query string, and intent-filter is unable to deal with
+            query parameters. An alternative would be to do something like fdroidswap:// as
+            a scheme, but then we. Need to copy/paste all of this intent-filter stuff and
+            keep it up to date when it changes or a bug is found.
