A handy way to push the current branch to the same name on the

-`git push origin master:satellite/master dev:satellite/dev`::
+`git push mothership master:satellite/master dev:satellite/dev`::
Use the source ref that matches `master` (e.g. `refs/heads/master`)
to update the ref that matches `satellite/master` (most probably
- `refs/remotes/satellite/master`) in the `origin` repository, then
+ `refs/remotes/satellite/master`) in the `mothership` repository;
do the same for `dev` and `satellite/dev`.

+This is to emulate `git fetch` run on the `mothership` using `git

+the work done on `satellite`, and is often necessary when you can
+only make connection in one way (i.e. satellite can ssh into
+mothership but mothership cannot initiate connection to satellite
+because the latter is behind a firewall or does not run sshd).
++
+After running this `git push` on the `satellite` machine, you would
+ssh into the `mothership` and run `git merge` there to complete the
+emulation of `git pull` that were run on `mothership` to pull changes
+made on `satellite`.

Push the current branch to the remote ref matching `master` in the
