`Best code here' with constraints

The preceding model can be completed with some additional limits, usually to get a wider gap of saleability of the code. The most common limit is the `delayed availability', where the author of the code imposes some artificial limit that decays with time or with successive releases of the software product. An example is Alladin with their GhostScript Postscript-compatible printing engine.
