-'''VARBLOCK file support
-
-The VARBLOCK file format is as follows, where || denotes byte concatenation:
-
-    FILE := VERSION || BLOCK || BLOCK ...
-
-    BLOCK := LENGTH || DATA
-
-    LENGTH := varint-encoded length of the subsequent data. Varint comes from
-    Google Protobuf, and encodes an integer into a variable number of bytes.
-    Each byte uses the 7 lowest bits to encode the value. The highest bit set
-    to 1 indicates the next byte is also part of the varint. The last byte will
-    have this bit set to 0.
-
-This file format is called the VARBLOCK format, in line with the varint format
-used to denote the block sizes.
