      Todoman is a simple, standards-based, cli todo (aka task) manager. Todos
      are stored into iCalendar files, which means you can sync them via CalDAV
      using, for example, vdirsyncer.

      Todos are read from individual ics files from the configured directory.
      This matches the vdir specification. There is support for the most common TODO
      features for now (summary, description, location, due date and priority) for
      now.
      Unsupported fields may not be shown but are never deleted or altered.
