-;; Version of the installation library
-;;
-;; The versioning scheme is as follows: a version is composed of three
-;; integers called (from left to right) "major", "minor" and
-;; "revision".
-;;
-;; Two versions which share a "major" and "minor" number must be fully
-;; compatible in that one should be exchangeable for the other without
-;; (important) change in behaviour.
-;;
-;; Two versions which share a "major" number must be compatible in an
-;; ascendent fashion: the features offered by the version with the
-;; greatest "minor" number must be a superset of those offered by the
-;; other.
-;;
-;; Two versions which do not even share a "major" number can be
-;; mutually incompatible.
-;;
-;; Clients using the installation library must specify which "major"
-;; and "minor" number they need --- if the above scheme is respected,
-;; the "revision" should not matter. This need is satisfied if the
-;; requested "major" number matches the one of the library, and the
-;; requested "minor" is smaller or equal to the one of the library.
