 Enlightenment 0.17.0 - IN DEVELOPMENT... not a RELEASE.
+
+NOTE: Users of DR16 will need to rename the $prefix/bin/enlightenment
+file prior to installing DR17 or it will be overwritten.
+
+You can also use the configure --prefix option to put e17 in a separate tree
+of its own (recommended) like:
+
+  ./configure --prefix=/usr/local/e17
+
+You will, as usual need to add the subsequent bin dir to your $PATH etc.
