-Block format doesn't deal with header information,

-This is the purpose of the Frame format.
-Interoperable versions of LZ4 should use the same frame format,

+Compressing an arbitrarily long file or data stream requires multiple blocks.
+Organizing these blocks and providing a common header format to handle their content
+is the purpose of the Frame format, defined into [lz4_Frame_format].
+Interoperable versions of LZ4 must respect this frame format too.
