devel/py-flatbuffers/pkg-descr

+FlatBuffers is a cross platform serialization library architected for maximum
+memory efficiency. It allows you to directly access serialized data without
+parsing/unpacking it first, while still having great forwards/backwards
+compatibility.
+
 Python runtime library for use with the Flatbuffers serialization format.
