class_docstr: The main top-level class that you instantiate once, or once per module.
  
  Example usage:
  
      ffi = FFI()
      ffi.cdef("""
          int printf(const char *, ...);
      """)
  
      C = ffi.dlopen(None)   # standard library
      -or-
      C = ffi.verify()  # use a C compiler: verify the decl above is right
  
      C.printf("hello, %s!\n", ffi.new("char[]", "world"))
