    """FlatBuffers C Compiler (flatcc), a memory-efficient serialization
    library, is implemented as a standalone tool instead of extending Googles
    flatc compiler in order to have a pure portable C library implementation of
    the schema compiler that is designed to fail graciously on abusive input in
    long running processes. It is also believed a C version may help provide
    schema parsing to other language interfaces that find interfacing with C
    easier than C++."""
