+#    - Or skip this step if you want to archive an existing directory tree
+# 2. Get name of directory to use as the top-level archive directory
+# 3. Pause to let user to update directory tree as needed
+# 4. Clean out unnecessary artifacts 
+#    - MacOS ".DS_Store" or "._" files
+#    - Arduino "installed.json" file
+# 5. Tar and compress (bz2) directory
+# 6. Calculate and save filesize and sha-256 checksum in file "size-and-checksum.txt"
