 Source: flatbuffers
 Version: 1.12.0
+Port-Version: 1
 Description: Memory Efficient Serialization Library
  FlatBuffers is an efficient cross platform serialization library for games and other memory constrained apps. It allows you to directly access serialized data without unpacking/parsing it first, while still having great forwards/backwards compatibility.
