This package provides traditional Hindu calendars (solar and lunar) using
analytic equations (Meeus-style) based on astronomical motions of the Sun and
Moon.  It calculates tithi and nakshatra.  It provides both tropical (sayana)
and sidereal (nirayana/Chitrapaksha) variants.  Lunar calendar can be chosen
between amanta or purnimanta.  Default location is Ujjain, which can be
customized via `calendar-latitude', `calendar-longitude' and
`calendar-time-zone'

Usage:
    All of the functions can be called interactively or programmatically.
