- 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
