+5.19 2011-03-12 Gregory Nutt <gnutt@nuttx.org>
+
+	* Initial version of the apps/ directory was released as contributed by
+	  Uros Platise.
+
+6.0 2011-03-21 Gregory Nutt <gnutt@nuttx.org>
+
+	* README.txt -- README cosmetics
+	* hello/ -- hello world minor changes
+	* Makefile -- Makefile cosmetics (I am slowly adding the Darjeeling JVM)
+	* Make.defs -- New file adds common make definitions for applications.
+	* hello/Makefile -- Now uses new Make.defs definitions.  Added README.txt.
+	* apps/poweroff -- New application to turn off board power.
+	* Moved NSH library, netutils, and examples from the nuttx/ directory to
+	  the apps/ directory
+	* Moved exec_nuttapp machinery into the nuttapp/ directory.
+
+6.1 2011-04-10 Gregory Nutt <gnutt@nuttx.org>
+
+	* Creation of auto-generated header files now occurs during the context
+	  build phase.
+	* Added sdcard insert and eject, nsh command '?' and some code remarks
+	* Renamed nuttapp to namedapp
+	* namedapp/binfs.c -- Create a tiny filesystem that can be used
+	  to show the internal named apps under /bin.
+	* Numerous fixes to build system required to support building with native
+	  Windows toolchain.
+
+6.2 2011-05-06 Gregory Nutt <gnutt@nuttx.org>
+
+	* apps/examples/nxffs:  Add a test a a configuration that will be used to
+	  verify NXFFS.
+
+6.3 2011-05-15 Gregory Nutt <gnutt@nuttx.org>
+
+    * apps/interpreter: Add a directory to hold interpreters.  The Pascal add-
+	  on module now installs and builds under this directory.
+	* apps/interpreter/ficl: Added logic to build Ficl (the "Forth Inspired
+	  Command Language").  See http://ficl.sourceforge.net/.
+	* apps/netutils/dhcpc, dhcpcd, and tftp.  If these directories are included
+	  in the configuration but CONFIG_NET_UDP is disable (which is not very wise),
+	  then a make error occurs because tools/mkdep.sh is called with no files.
+	* system/free: Move Uros' custom free command from vsn/free
+	* system/install: Add a new install command submitted by Uros Platise.
+	* examples/rgmp.  Add a placeholder for an RGMP build example.
+	  RGMP is a project for running GPOS and RTOS simultaneously on
+	  multi-processor platforms. See http://rgmp.sourceforge.net/wiki/index.php/Main_Page
+	  for further information about RGMP.  NOTE:  This is an empty example
+	  on initial check-in.
+
+6.4 2011-06-06 Gregory Nutt <gnutt@nuttx.org>
+
+	* nshlib/nsh_netcmds.c: If a network device name and IP address are provided
+	  with the ifconfig command, then this command will now set the network address.
+	  (Contributed by Yu Qiang).
+	* netutils/ftpc: A library to support client-side FTP.
+	* examples/ftpc: A simple add-on to the NSH.  From NSH, you can start
+	  this simple FTP shell to transfer files to/from a remote FTP server.
+
+6.5 2011-06-21 Gregory Nutt <gnutt@nuttx.org>
+
+	* netutils/ftpc:  Simpflication and size reduction.
+
+6.6 2011-07-11 Gregory Nutt <gnutt@nuttx.org>
+
+	* Make.defs, namedapp/namedapp.c: Several structural changes made to get a
+	  clean compile under the ez80 ZDS-II toolchain (no design changes).
+	* apps/examples/buttons: Add a test for the new standardized button interfaces
+	* apps/examples/nxtext: Add another NX graphics test.  This one focus on
+	  placing text on the background while pop-up windows occur.  Text should
+	  continue to update normally with or without the popup windows present.
+
+6.7 2011-08-02 Gregory Nutt <gnutt@nuttx.org>
+
+	* apps/examples/nx and nxtext:  These examples can now be built as NSH
+	  "built-in" commands.
+	* apps/examples/nxhello:  The simplest graphics example:  It just says
+	  "Hello, World!" in the center of the display. This example can also be
+	  built as an NSH "built-in" command.
+	* apps/examples/nx, ntext, and nxhello:  All updated to use the new
+	  NuttX font interfaces.
+	* apps/examples/nximage:  Another super simple  graphics example:  It just puts
+	  the NuttX logo in the center of the display. This example can also be
+	  built as an NSH "built-in" command.
+	* apps/examples/usbstorage: Can now be built as two NSH "built-in" commands:
+	  'msconn' will connect the USB mass storage device; 'msdis' will disconnect
+	  the USB storage device.
+	* apps/examples/nx*:  All NX header files moved from nuttx/include/nuttx to 
+	  nuttx/include/nuttx/nx.
+	* apps/examples/usbstorage: Added instrumentation to monitor memory usage
+	  to check for memory leaks in the USB storage driver.
+	* apps/examples/nxhello/nxhello_bkgd.c:  Fix handling of allocated glyph
+	  memory.
+
+6.8 2011-08-11 Gregory Nutt <gnutt@nuttx.org>
+
+	* apps/examples/nxlines:  Added a test for NX line drawing capabilities.
+
+6.9 2011-09-11 Gregory Nutt <gnutt@nuttx.org>
+
+	* apps/examples/nxlines:  Extend the line drawing text to include drawing
+	  of circles.
+	* apps/system/i2c:  Add an I2C test tool that should help to bring up I2C
+	  devices (when it is fully functional).
+	* apps/nshlib/nsh_timcmds.c:  Add the date command that can be used to
+	  show or set the time (only if CONFIG_RTC is set).
+
+6.10 2011-10-06 Gregory Nutt <gnutt@nuttx.org>
+
+	* apps/system/i2c:  Add repitition and address auto-incrementing so that
+	  and command can be executed numerous times.  Add a new verify command
+	  that will write to a register, read from register, and verify that
+	  returned value.
+	* apps/graphics/tiff:  Add a library that can be used to create TIFF files.
+	* apps/examples/tiff:  Add a unit test for the TIFF file creation logic
+	* apps/examples/lcdrw:  Add a test to verify if you can or can or read
+	  data from an LCD correctly.
+	* apps/examples/usbterm:  A USB terminal example.. more of a USB chat or
+	  serial bridge:  Data received on local console echoed via USB serial; 
+	  data received on USB serial is echoed on the local console.
+	* apps/examples/touchscreen:  Add a simple, generic test for any
+	  touschscreen driver.
+	* Makefile:  The apps/ Makefile now checks for an apps/external directory
+	  or symbolic link.  If such a directory/link exists (and has a Makefile),
+	  it will be added to the apps/ build.  This allows external directories
+	  to be included into the apps/ build by simply creating a symbolic link.
+
+6.11 2011-11-12 Gregory Nutt <gnutt@nuttx.org>
+
+	(No major changes from 6.10)
+
+6.12 2011-12-06 Gregory Nutt <gnutt@nuttx.org>
+
+	* apps/examples/buttons:  The button test can now be executed as an NSH
+	  built in command.
+
+6.13 2012-12-26 Gregory Nutt <gnutt@nuttx.org>
+
+	* apps/examples/dhcpd: May now be built as an NSH built-in application
+	  by setting CONFIG_NSH_BUILTIN_APPS.
+	* apps/netutils/dhcpd/dhcpd.c: Fix several problems using host order address
+	  where network addresses expected (and vice versa).
+	* apps/examples/nettest: May now be built as an NSH built-in application
+	  by setting CONFIG_NSH_BUILTIN_APPS.
+	* apps/examples/nettest: Correct some build issues with the nettest is
+	  built for performance evaluation.
+	* apps/examples/adc:  Add a very simple test to drive and test an ADC
+	  driver.
+	* apps/examples/pwm:  Add an NSH PWM command to drive and test a PWM
+	  driver.
+	* apps/examples/can:  Add an NSH CAN command to drive and test a CAN
+	  driver in loopback mode.
+
+6.14 2012-01-15 Gregory Nutt <gnutt@nuttx.org>
+
+	* apps/examples/buttons/main.c:  The test needs to call up_buttoninit() to
+	  properly configure the button interrupt GPIOs.
+	* apps/examples/pwm:  Add support to test the pulse count option recently
+	  added to the PWM interface.
+
+6.15 2012-02-12 Gregory Nutt <gnutt@nuttx.org>
+
+	* apps/nshlib/nsh_serial.c and nsh_usbdev.c:  If NuttX is configured to use
+	  a USB serial console, then NSH needs to wait until the USB console is
+	  connected and available.
+	* apps/examples/composite:  Add a test of the USB composite device.
+	* apps/examples/Telnetd:  Move the tiny uIP shell example from
+	  netutils/Telnetd to examples/Telnetd.  Enhanced the Telnetd daemon so that
+	  it supports Telnetd via a TTY device driver: A new TTY device driver is
+	  created when each new Telnet connection is created.  The shell thread
+	  is started with stdin, stdout, and stderr mapped to the TTY device.
+	* netutils/Telnetd:  The old uIP Telnet demo is gone.  In its place is a new
+	  Telnet infrastructure. The new Telnet daemon creates sessions that are
+	  "wrapped" as character devices and mapped to stdin, stdout, and stderr.
+	  Now the Telnet session can be inherited by spawned tasks.
+	* examples/Telnetd:  Add a test for the new Telnet daemon.
+	* examples/Telnetd/telnetd_driver.c: Move the internal socket structure from
+	  the daemon's socket array into the driver's state data so that it will be
+	  independent from the the Telnetd daemon.
+	* apps/system/readline:  Moved the old nuttx/lib/stdio/lib_fgets.c here
+	  and renamed it as readline().  The old fgets was simplied and the overloaded
+	  readline functionality was removed.
+	* apps/netutils/ftpd:  Add an FTPD server (does not even compile on initial
+	  checkin).
+	* apps/examples/ftpd:  Add a test for the FTPD server (untest on initial
+	  check-in).
+	* apps/nshlib/nsh_fscmds.c:  Add support for a 'dmesg' command that will
+	  dump the system log if CONFIG_SYSLOG is selected.
+
+6.16 2012-03-10 Gregory Nutt <gnutt@nuttx.org>
+
+	* apps/examples/qencoder:  Add a quadrature driver test.
+	* apps/examples/ostest/fpu.c:  Add a test to verify that FPU registers
+	  are properly saved and restored on context switches.
+	* apps/system/readline/readline.c:  readline() will now treat either a
+	  backspace or a DEL character as a backspace (i.e., deleting the character
+	  to the left of the cursor).  This makes NSH less dependent on particular
+	  keyboard mappings of the Backspace key.  Submitted by Mike Smith.
+	* apps/examples/cdcacm:  An example that illustrates how the CDC/ACM driver
+	  may to connected and disconnected through software control.
+	* apps/examples/nsh/nsh_main.c:  If available, call up_cxxinitialize() to
+	  initialize all statically defined C++ classes.
+	* apps/nshlib:  Now supports a USB serial device for NSH console I/O.  This
+	  allows NSH to be used on boards that have USB but no serial connectors.
+
+6.17 2012-04-14 Gregory Nutt <gnutt@nuttx.org>
+
+	* apps/examples/can:  Add conditional compilation so that the test can be
+	  configured to only send messages or to only receive messages.  This will
+	  let the test work in other modes than simple loopback testing.
+	* apps/examples/hello and apps/examples/ostest:  Can now be built as NSH
+	  built-int functions.
+	* vsn/hello:  Removed.  The modified apps/examples/hello is enough "Hello,
+	  World!"
+	* apps/examples/nxconsole:  Add a test of the NX console device.
+	* apps/examples/nxconsole:  The NX console example now supports running
+	  the NuttShell (NSH) within an NX window.
+	* apps/system/readline:  Now uses standard definitions from
+	  include/nuttx/ascii.h and vt100.h
+	* Kconfig, */Kconfig:  Added skeleton Kconfig files to all directories that
+	  may need them.
+
+6.18 2012-05-19 Gregory Nutt <gnutt@nuttx.org>
+
+	* Kconfig:  Continued Kconfig file updates (no longer tracking on a per-file
+	  basis in the ChangeLog)
+	* apps/examples/watchdog:  Add a watchdog timer example.
+	* apps/examples/tiff:  Fix wrong path used for temporary file.
+	* apps/examples/touchscreen:  Standardize the board-specific, touchscreen
+	  initialization interfaces.
+
+6.19 2012-06-15 Gregory Nutt <gnutt@nuttx.org>
+
+	* apps/nshlib/nsh_usbdev.c:  Add the capability to use an arbitrary USB
+	  device as the console (not necessarily /dev/console).  This is a useful
+	  option because then you can still use the serial console to debug with.
+	* apps/nshlib/nsh_usbdev.c:  User now has to press ENTER 3 times before
+	  USB console will start.  Otherwise, the USB console starts before there
+	  is anyone at the other end to listen.
+	* apps/nshlib/nsh_usbdev.c and nsh_consolemain.c:  Add support for the USB
+	  capability when a USB console is used.
+	* apps/nshlib/nsh_fscmds.c:  Add the 'mv' command
+
+6.20 2012-07-12 Gregory Nutt <gnutt@nuttx.org>
+
+	* namedapp/exec_namedapp.c - Correct an error when round robin scheduling
+	  is enabled.  The priority of the new, named application was erroneously
+	  being set to the priority of the parent thread; losing its configured
+	  priority.  Reported by Mike Smith.
+
+6.21 2012-08-25 Gregory Nutt <gnutt@nuttx.org>
+
+	* apps/include/: Stylistic clean-up of all header files.
+	* apps/modbus and apps/include/modbus:  A port of freemodbus-v1.5.0
+	  has been added to the NuttX apps/ source tree.
+	* apps/examples/modbus:  A port of the freemodbus-v1.5.0 "demo"
+	  program that will be used to verify the FreeModBus port
+	* apps/modbus:  Don't use strerror().  It is just too big.
+	* apps/modbus:  Add CONFIG_MB_TERMIOS.  If the driver doesn't support
+	  termios ioctls, then don't bother trying to configure the baud, parity
+	  etc.
+	* apps/nshlib:  If waitpid() is supported, then NSH now catches the
+	  return value from spawned applications (provided by Mike Smith)
+	* apps/nshlib:  Lock the scheduler while starting built-in applications
+	  in order to eliminate race conditions (also from Mike Smith).
+	* apps/examples/adc, pwm, and qencoder:  Add support for testing
+	  devices with multiple ADC, PWM, and QE devices.
+	* apps/nshlib/nsh_mntcmds.c:  Separated mount-related commands out of
+	  nsh_fscmds.c.  Extended to the mount command so that if no arguments
+	  are provided, then the current mountpoints are enumerated.
+	* apps/nshlib/nsh_mntcmds.c:  Add an NSH df command to list the
+	  properties of mounted file systems.
+	* apps/nshlib/nsh_parse.c:  Extend help command options.  'help' with
+	  no arguments outputs a short list of commands.  With -v lists all
+	  command line details.  A command name can be added to just get
+	  help on one command.
+	* system/readline.c:  If character input/output is interrupted by a
+	  signal, then readline() will try the read/write again.
+	* apps/*/Make.defs:  Numerous fixes needed to use the automated
+	  configuration (from Richard Cochran).
+
+6.22 2012-xx-xx Gregory Nutt <gnutt@nuttx.org>
+
+	* apps/netutils/thttpd/thttpd_cgi.c:  Missing NULL in argv[]
+	  list (contributed by Kate).
+	* apps/nshlib/nsh_parse.c: CONFIG_NSH_DISABLE_WGET not CONFIG_NSH_DISABLE_GET
+	  in one location (found by Kate).
+	* apps/examples/ostest/prioinherit.c:  Limit the number of test
+	  threds to no more than 3 of each priority.  Bad things happen
+	  when the existing logic tried to created several hundred test
+	  treads!
+	* apps/nshlib/nsh.h:  Both CONFIG_LIBC_STRERROR and CONFIG_NSH_STRERROR
+	  must be defined to use strerror() with NSH.
+	* apps/examples/*/*_main.c, system/i2c/i2c_main.c, and others:  Added
+	  configuration variable CONFIG_USER_ENTRYPOINT that may be used to change
+	  the default entry from user_start to some other symbol.  Contributed by
+	  Kate.
+	* apps/netutils/webserver/httpd/c:  Fix a typo that as introduced in
+	  version r4402:  'lese' instead of 'else' (Noted by Max Holtzberg).
+	* tools/mkfsdata.pl: The uIP web server CGI image making perl script was
+	  moved from apps/netutils/webserver/makefsdata to nuttx/tools/mkfsdata.pl
+	  (Part of a larger change submitted by Max Holtzberg).
+	* apps/netutils/webserver, apps/examples/uip, and apps/include/netutils/httpd.h:
+	  The "canned" version of the uIP web servers content that was at 
+	  netutils/webserver/httpd_fsdata.c has been replaced with a dynamically
+	  built configuration located at apps/examples/uip (Contributed by
+	  Max Holtzberg).
+	* apps/netutils/webserver:  Several inenhancements from Kate including the
+	  ability to elide scripting and SERVER headers and the ability to map
+	  files into memory before transferring them.
+	* apps/netutils/webserver:  Add ability to map a URL to CGI function.
+	  Contributed by Kate.
+	* apps/nshlib/nsh_mntcmds.c: The changes of 6.21 introduced holes in the
+	  error handling:  Now the number of arguments to mount can be 0 or 4.
+	  Additional parameter checking is required to prevent mysterious errors
+	  (submiteed by Kate).
+	* apps/netutils/webserver/httpd_mmap.c:  Fix errors when the mmap()
+	  length is zero (submitted by Kate).
+	* apps/netutils/webserver/httpd_sendfile.c:  Add and option,
+	  CONFIG_NETUTILS_HTTPD_SENDFILE to transfer files using the NuttX
+	  sendfile() interface.
+	* apps/netutils/discover:  A UDP network discovery utility contributed
+	  by Max Holtzberg.
+	* apps/examples/discover:  A test example for the UDP network discovery
+	  utility (also contribed by Max Holtzberg).
+	* apps/examples/*/main.c:  Too many files called main.c.  Each renamed
+	  to something unique so that they will not collide in the archive.
+	* apps/netutils/xmlrpc: The Embeddable Lightweight XML-RPC Server
+	  discussed at http://www.drdobbs.com/web-development/\
+	  an-embeddable-lightweight-xml-rpc-server/184405364.  Contributed by
+	  Max Holtzberg.
+	* apps/netutils/uip_listenon.c:  Logic in uip_server.c that creates
+	  the listening socket was moved to this new file to support re-use.
+	  Contributed by Kate.
+
