+"""Upload results tarballs to a Pbench Server
+
+This utility supports bulk migration of results tarballs to a Pbench Server.
+
+It's a standalone utility (with no dependency on any Pbench packages) that can
+be used to send a specific tarball or a potentially large set of tarballs to a
+server. It supports filtering by file modification date, and checkpointing to
+allow restarting in case of a failure. It can be run in a "preview" mode to
+identify the selected tarballs without uploading.
+
+`pbench-upload-results.py https://<server> /srv/pbench/backup` will upload all
+result tarballs nested under the directory `/srv/pbench/backup`. You can use
+the `--since` and `--before` timestamp selectors to include only results files
+modified "since" (>=) and/or "before" (<) the specified datetimes. Specify a
+checkpoint file with `--checkpoint <file>` to record all results successfully
+uploaded; after unexpected termination (e.g., crash or ^C), rerunning the same
+command will skip the already uploaded files.
+
+Uploaded files are marked with metadata consistent with the behavior of the
+0.69-11 passthrough server. If the script is run on a Pbench server, metadata
+will record the version string and SHA1 of the Pbench installation. We also
+record the hostname, and a marker that it was "migrated" by this utility.
