From 8ee78c14af3b9974ad96cf85f6ea32c4e254f958 Mon Sep 17 00:00:00 2001

Subject: Add calcurse-dateutil
Add a script to iterate over a certain date range, performing operations
on each of the dates and printing the result. An additional string can
be appended to each of the printed lines.
The script can be used to create "extended recurrent events". For
example
./calcurse-dateutil.py --date 2017-01-01 --range 365 --unique \
--append ' [1] Test event' bom next-weekday 3 skip-days 14
can be used to print an event for each third Thursday of each month in
2017.
