+%description
+Package 'bit64' provides serializable S3 atomic 64bit (signed) integers. These
+are useful for handling database keys and exact counting in +-2^63. WARNING: do
+not use them as replacement for 32bit integers, integer64 are not supported for
+subscripting by R-core and they have different semantics when combined with
+double, e.g. integer64 + double => integer64. Class integer64 can be used in
+vectors, matrices, arrays and data.frames. Methods are available for coercion
+from and to logicals, integers, doubles, characters and factors as well as many
+elementwise and summary functions. Many fast algorithmic operations such as
+'match' and 'order' support interactive data exploration and manipulation and
+optionally leverage caching.
