  56      "Gcal is a program to calculate and print calendars on the
  57 command-line.  Calendars can be printed in 1-month, 3-month or whole-year
  58 views.  In addition, eternal holiday lists can be generated for many
  59 countries, which can be complemented by user-made lists of fixed dates to
  60 make an agenda.  Gcal can also calculate astronomical data, such as the
  61 phases of the moon, and supports alternative calendar formats: Julian,
  62 Gregorian, Islamic, Chinese and more.")
