+  Initialization phases:
+
+      - Load Lualibs from package
+      - Set up the logger routines
+      - Load Fontloader
+          - as package specified in configuration
+          - from Context install
+          - (optional: from raw unpackaged files distributed with
+            Luaotfload)
+
+  The initialization of the Lualibs may be made configurable in the
+  future as well allowing to load both the files and the merged package
+  depending on a configuration setting. However, this would require
+  separating out the configuration parser into a self-contained
+  package, which might be problematic due to its current dependency on
+  the Lualibs itself.

+    The logger needs to be in place prior to loading the fontloader due
+    to order of initialization being crucial for the logger functions
