Pack file format
- Top level: <length><packed container>
+ Top level: <packed container>
We always apply data compression to the pack file - using the
SVN_DELTA_COMPRESSION_LEVEL_NONE level if compression is disabled.
- <length> is being encoded using the variable-length svndiff unsigned
- integer format (see svndiff.c): 7 bits / byte in little endian order
- with the MSB of each byte indicating whether there is a another byte
- to read.
+ (Note that compression at SVN_DELTA_COMPRESSION_LEVEL_NONE is not
+ a no-op stream transformation although most of the data will remain
+ human readable.)
