Module `Irmin_pack.Version`Source

Management of disk-format versions.

`V2 introduced the *_v2 kinds and deprecated the *_v1 ones. The upgrade of a pack file to `V2 was done silently the first time a used pushed a *_v2 entry to the pack file.

`V3 introduced the control file. It centralizes all the metadata that used to be contained in the header of other files (e.g. the version of the store used to be stored in each files, it is now solely stored in the control file). The upgrade of a store to `V3 was done silently when opening a store in rw mode.

`V4 introduced the chunked suffix. Upgrade from `V3 happened on first write to the control file.

`V5 introduced the lower layer. Upgrade happened on first write to the control file.
