+# written to be easy to understand (and reason about) what it is
+# doing; this is why there are `for` loops around `scp` rather than
+# tarballing up a bunch of file and shipping them to remote machines,
+# unpacking them there. This is (mostly) why there are some
+# long_variable_names. I plan to keep it that way.
