+Produce set-theorhetic union of several Android manifests. Each project
+appearing in any manifest gets output once, and at most once, to the
+resulting manifest. Differences in checkout path/branch are ignored -
+values from a random occurance are output in result. The output is
+mostly intended for usage with "repo init --mirror", to produce mirror
+which contains all repositories used by a number of manifests.
