+  - read in file .sst .ssi .ssm
+  - loop twice
+    - first
+      - check for and skip code blocks
+      - use unique code marker for endnote markers in text and give an endnote
+        number ★1, increment
+      - extract all endnotes in array
+    - second
+      - check that the footnote marker number count matches the number of notes
+        in the array
+        - if they match either:
+            - substitute each endnote marker with the array footnote[number-1]
+            - substitute each endnote marker with footnote
+              as inlined footnote markup (footnote number not needed)
+        - if they do not match exit
+  - check whether changes have been made
+    - if so write file with inline footnotes in sub-directory converted_output_/
+      using the same name as the original file
+    - else, exit
