+%description
+This package consists of a C library and a Perl module (which uses the C library,
+internally) for all kinds of date calculations based on the Gregorian calendar
+(the one used in all western countries today), thereby complying with all
+relevant norms and standards: ISO/R 2015-1971, DIN 1355 and, to some extent,
+ISO 8601 (where applicable).
