+- Make it easier to change modules from builtin to externally loaded.
+
+    have: MODULE_INFO(name, init, destroy, { require} ) in each module.
+    Maintain the list of builtin modules and search these first (or 
+    optionally last). Add the lib prefix if needed to avoid having to
+    specify libbatchAnalysis instead of batchAnalysis.
+
+- Define formally traceset/trace in the GUI for the user and decide how
+   trace/traceset sharing goes in the application.
+
+- Use appropriately the new functions in time.h
+
+- remove the separate tracefiles (control/per cpu) arrays/loops in context.
+
+- split processTrace into context.c and processTrace.c
+
+- check spelling conventions.
+
+- get all the copyright notices.
+
+- remove all the warnings.
+
+- get all the .h files properly doxygen commented to produce useful documents.
+
+- have an intro/architecture document.
+
+- write a tutorial */
