DepCache - Dependency Extension data for the cache
This structure is important to support the readonly status of the cache
file. When the data is saved the cache will be refereshed from our
- internal rep and written to disk. Then the actual persistant data
+ internal rep and written to disk. Then the actual persistent data
files will be put on the disk.
Each dependency is compared against 3 target versions to produce to
