Some workflows require coordinated development between repositories on
machines that can never be connected. This utility creates a bundle
containing a pack of objects and associated references (heads or tags)
that can be independently transferred to another machine, effectively
supporting git-push like operations between disconnected systems.

+#!/bin/sh
+# Create a bundle to carry from one git repo to another (e.g., "sneaker-net" based push)
+# git-bundle <git-rev-list args>
+# git-bundle --bare <git-rev-list args>
+# creates bundle.zip in current directory (can rename of course)
+#
+# The bundle includes all refs given (--all selects every ref in the repo).
+# and all of the commit objects needed subject to the list given.
+#
+# Objects to be packed are limited by specifying one or more of
+# ^commit-ish - indicated commits already at the target (can have more than one ^commit-ish)
+# --since=xxx - Assume target repo has all relevant commits earlier than xxx
