+# init - Initialize the repo with a base commit and changes:
+#   - Source will be an 'import' branch containing all current configs.
+#   - Create an empty 'BASE' branch from 'init-repo'.
+#   - Add Marlin config files, but reset all to defaults.
+#   - Commit this so changes will be clear in following commits.
+#   - Add changed Marlin config files and commit.
+#
+# manual - Manually import changes from the Marlin repo
+#   - Replace 'default' configs with those from the Marlin repo.
+#   - Wait for manual propagation to the rest of the configs.
+#   - Run init with the given 'source' and 'dest'
