Better to write this as:

  let rec main () =
    ...

  and open_source ... =
    ...

  and amend_source ... =
    ...

  and inspect_source ... =
    ...

so it's consistent with how all the other sub-functions are
done in the same file.

'let rec .. and ..' defines mutually recursive functions that can call
each other.

Rich.
