++ NPLib
+-------
+  + General
+    Building NPLib is now easier. 
+    + The new 'scripts' directory holds bash scripts called by the main
+      Makefile at the NPLib level.
+    + The main Makefile calls several scripts:
+      + All headers files are moved to the 'include' directory.
+      + Each Makefile found in any subdirectory is called.
+      + All libraries are moved to the 'library' directory.
+      + Symbolic links to *.dylib files are done if on a macosx platform.
+      + The 'liblist' file at NPLib level is created.
+
+  + NPOptionManager facility
+    + This singleton class allows to pass arguments on the command line when
+      executing NPSimulation and NPAnalysis.
+    + Execute ./Simulation --help or ./Analysis --help to know the available 
+      options.
+
+  + RootInput facility
+    + Support for adding TFriend object
+
+  + NPTagManager facility
