class Half(Package):
"""This is a C++ header-only library to provide an IEEE-754 conformant
half-precision floating point type along with corresponding
arithmetic operators, type conversions and common mathematical
functions. It aims for both efficiency and ease of use, trying to
accurately mimic the behaviour of the builtin floating point types
at the best performance possible. It automatically uses and
provides C++11 features when possible, but stays completely
C++98-compatible when neccessary."""
