+All the documentation, whether it targets users or developers, is made
+of architecture-independent files. More it needs some rather special
+tools to be built (db2html, dblatex, Docbook stylesheets, and so on).
+So we want distribute it.
+
+There are so in the Makefiles some hacks so that:
+a) the built objects are distributed
+b) the distributed objects are installed without requiring to be
+   rebuilt.
