1This directory contains the classes that form the data model of Kyua. 2 3The classes in this directory are intended to be pure data types without 4any complex logic. As such, they are simple containers and support the 5common operations you would expect from them: in particular, comparisons 6and formatting for debugging purposes. 7 8All the classes in the data model have to have an on-disk representation 9provided by the store module; if they don't, they don't belong in the 10model. Some of these classes may also have special behavior at run-time, 11and this is provided by the engine module. 12
