* Gcal: (gcal).              The GNU calendar program.
END-INFO-DIR-ENTRY

  This file documents Gcal, a program for printing calendars.  Gcal
displays a calendar for a month or a year, eternal holiday lists and
fixed date warning lists, in many ways.  The program correctly omits
the dates that were skipped when the current Gregorian calendar
replaced the earlier Julian calendar.
