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
