%description
'Int64' values can be created and accessed via the 'bit64' package and its
'integer64' class which package the 'int64' representation cleverly into a
'double'. The 'nanotime' packages builds on this to support
nanosecond-resolution timestamps. This packages helps conversions between
'R' and 'C++' via several helper functions provided via a single header
file.  A complete example client package is included as an illustration.
