The difference is that you can do the following: r-base-core Provides: r-base-api-3 and all cran depends on r-base-api-3. When the API changes incompatibly, and an entire rebuild is required, you change the api, so that r-base-core now Provides r-base-api-4. Now, all cran packages have to be upgraded in lockstep with R, and you cannot have R packages installed which are incompatible with the R interpreter. The version number attached to the API only increments when the API changes incompatibly. If the API changes in a complex way, you could also conceivably provide multiple versions of the API in the base package. Don Armstrong -- Tell me something interesting about yourself.
