6 | Version - Versioning system.. |
7 | ||
8 | The versioning system represents how versions are compared, represented | |
9 | and how dependencies are evaluated. As a general rule versioning | |
10 | systems are not compatible unless specifically allowed by the | |
11 | TestCompatibility query. | |

13 | The versions are stored in a global list of versions, but that is just |
14 | so that they can be queried when someone does 'apt-get -v'. | |
15 | pkgSystem provides the proper means to access the VS for the active | |
16 | system. | |
