+Changes in version 1.1 (released 2004-05-22)
+--------------------------------------------
+
+The installation library itself is now installed as a scsh package
+called "install-lib". The "scsh-install-pkg" script is just a wrapper
+around this library.
+
+As a consequence, the meaning of the "--prefix" option passed to the
+installation script changed: it is now the prefix to use to install
+the "install-lib" package. All the files but the wrapper script are
+installed below this prefix, according to the chosen layout. The
+wrapper script itself is put in the directory specified by the
+"--bindir" option.
+
+To comply with the packaging policy, some files were also renamed.
+Most importantly, the name of the documentation changed from
+"proposal.pdf" to "install-lib.pdf".

+;;
+;; 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.
