Chunked @file{FILE} produces @file{FILE.nncp.meta},
@file{FILE.nncp.chunk0}, @file{FILE.nncp.chunk1}, ... files. All
@file{.nncp.chunkXXX} can be concatenated together to produce original
-@file{FILE}. @file{.nncp.meta} contains information about file/chunk
-size and their hash checksums:
+@file{FILE}.

+@file{.nncp.meta} contains information about file/chunk
+size and their hash checksums. This is
+@url{https://tools.ietf.org/html/rfc4506, XDR}-encoded structure:
@verbatim
+------------------------------+---------------------+
Whole reassembled file's size
@item Chunk size @tab
unsigned hyper integer @tab
- Size of each chunks (except for the last one, that could be smaller).
+ Size of each chunk (except for the last one, that could be smaller)
@item Checksums @tab
variable length array of 32 byte fixed length opaque data @tab
BLAKE2b-256 checksum of each chunk
