 	* apps/system/readline and apps/nshlib:  Add support for an in-memory
 	  command line history that can be retrieved using the up and down
 	  arrows.  Contributed by Nghia Ho (2015-08-09).
+	* apps/Makefile:  No longer depends on hardcoded lists of directories.
+	  Instead, it does a wildcard search to find all appropriate
+	  directories.  This means that to install a new application, you
+	  simply have to copy the directory (or link it) into the apps/
+	  directory.  If the new directory includes a Makefile and Make.defs
+	  file, the it will automatically be included in the build (2015-08-11).
+	* apps/Makefile, Kconfig, */Kconfig, tools/mkkconfig.sh: Add the tool
+	  mkkconfig.sh that dynamically builds the apps/Kconfig file at
+	  configuration time.  The hardcoded configuration file has been removed
+	  and now the top-level Makefile executes tools/mkkconfig.sh to auto-
+	  generate the top-level Kconfig file.  A new apps/ make target call
+	  preconfig: was added to support this operation.  Now you do not have
+	  to modify the top-level Kconfig file to add a new directory into the
+	  configuration; the top-level subdirectory simply needs to include a
+	  Kconfig file and it will automatically be included in the
+	  configuration.  The native Windows build is temporarily broken until
+	  a new apps/tools/mkconfig.bat script is generated (2015-08-11).
