Version: $VERSION

Converts the AOB in Markdown format for a particular month to HTML and to text

Options:
  -h                    Print this help
  -D                    Select debug mode (works the same; more output)

Arguments (optional):
    date                Specifies the month to build the AOB for. The default
                        is the current month. The format can be YYYY-MM (e.g.
                        2022-05) or any date format that the 'date' command
                        can parse, so 2022-04-01 or 01-Apr-2022 and so on. If
                        the date cannot be parsed an error will be reported.

Examples
  ./${SCRIPT} -h
  ./${SCRIPT} -D 01-February-2021
  ./${SCRIPT} 2021-02
