+Dotconf use a two numbers X.Y versioning. The Y part is incremented by one on
+each release. The X part is used as API compatibility indicator and will be
+incremented each time the API is broken. When this part is incremented, the Y
+part is *not* reseted, but also incremented. So if the current version is
+1.12, and the API broken, the next release will be 2.13.
+This particular versioning allow to backport features and bugfix with old API
+(eg: 1.12 have same features than 2.12, modulo the API changes).
