+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.
+
+Features:
+ - Access to serialized data without parsing/unpacking
+ - Memory efficiency and speed. The only memory needed to
+   access your data is that of the buffer.
+ - Flexible. Optional fields provides forwards and backwards
+   compatibility.
+ - Tiny code footprint. Small amounts of generated code, and
+   just a single small header as the minimum dependency.
+ - Strongly typed. Errors happen at compile time.
+ - Convenient to use. Generated C++ code allows for terse
+   access & construction code.
+ - Cross platform code with no dependencies.
+
+Protocol Buffers is indeed relatively similar to FlatBuffers,
+with the primary difference being that FlatBuffers does not
+need a parsing/unpacking step to a secondary representation
+before you can access data, often coupled with per-object
+memory allocation. The code is an order of magnitude bigger,
+too. Protocol Buffers has neither optional text import/export
+nor schema language features like unions.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
