r212032:

    Use basename(3) to determine the name of the program.

    Submitted by:   Alexander Best <arundel@>

r205427:

    Replace -b with -C and -B (as proposed by Alexander).
    Add -3, -A and -B to the usage.
    Update regression test for the new parameters.

r205071:

    - With the introduction of -A, -B and -3, not all combinations of
      arguments makes sense anymore. For example, what would a combination
      of -3 (show three months) and -y (show the whole year) do?
      We will abort on these cases.
    - Move the debug option -d to -H (from highlight), while -d is now
      used for setting the day of "today" so that -y and friends can
      be tested.

r204908:

    - Fix the highlighting for non-terminals when the last week is not
      7 days long.
    - "-m <N> <YYYY>" now prints only the month, not the whole year.

r204849:

    - document the -3, -A and -B properly in Synopsis.
    - add highlight of current date for non-terminals.
    - fix -J option.
    - code cleanup.

r204706:

Remove no-op of WARNS?=

    Submitted by:   Ulrich Sp??rlein <uqs@spoerlein.net>

r204697:

    - Implement -3 option (show previous, this and next month) option.
    - Add -A option (months after this month).
    - Add -B option (months before this month).
    - Fix highlighting of today in year overview.
    - Fix aligning of "foreign" characters.
