 /* modules.h
- * Definition for build-in and plug-ins module handler.
  *
- * The following definitions are to be used for modularization. Currently,
- * the code is NOT complete. I am just adding pieces to it as I
- * go along in designing the interface.

+ * Definition for build-in and plug-ins module handler. This file is the base
+ * for all dynamically loadable module support. In theory, in v3 all modules
+ * are dynamically loaded, in practice we currently do have a few build-in
+ * once. This may become removed.
  *
+ * The loader keeps track of what is loaded. For library modules, it is also
+ * used to find objects (libraries) and to obtain the queryInterface function
+ * for them. A reference count is maintened for libraries, so that they are
+ * unloaded only when nobody still accesses them.
