%description
The Chinese Lunar Calendar is mostly based on the motion of the Moon. It
is said due to the complicate interaction, mostly from the Sun and the
Earth, the motion of Moon is very hard to predict, especially on the long
run. Luckily Hong Kong Observatory has published a conversion table for
the period from 1901 to 2100. It is the most trustworthy Lunar Calendar
on the web so far.

Lunar calendar beyond 1901-2100 range is generated by finding solar terms
and moon phases uses VSOP87 planetary theory and LEA-406 lunar theory.

The full version of LEA-406 and VSOP87 are used by default.
This package skips the Python version and just installs C version.
