+NuttX Configuration Tool from DOS
+---------------------------------
+
+Recent versions of NuttX support building NuttX from a native Windows
+CMD.exe shell (see "Native Windows Build" below).  But kconfig-frontends
+is a Linux tool.  There have been some successes building a Windows
+native version of the kconfig-frontends tool, but that is not ready
+for prime time.
+
+At this point, there are only a few options for the Windows user:
+
+  1. You can run the configuration tool using Cygwin.  However, the
+     Cygwin Makefile.win will complain so to do this will, you have
+     to manually edit the .config file:
+
+      a. Delete the line: CONFIG_WINDOWS_NATIVE=y
+      b. Change the apps/ directory path, CONFIG_APPS_DIR to use Unix
+         style delimiters.  For example, change "..\apps" to "../apps"
+
+     And of course, after you use the configuration tool you need to
+     restore CONFIG_WINDOWS_NATIVE=y and the correct CONFIG_APPS_DIR.
+
+  2) You can, with some effort, run the the Cygwin mconf tool directly
+     in the CMD.exe shell.  In this case, you do not have to modify the
+     .config file, but there are other complexities:
+
+      a. You need to temporarily set the Cgywin directories in the PATH
+         variable then run mconf manually like:
+
+          mconf Kconfig
+
+         There is a Windows bacht file at tools/kconfig.bat that automates
+         these steps:
+
+         tools/kconfig menuconfig
+
+       b. There is an issue with accessing DOS environment variables from
+          the Cygwin mconf running in the CMD.exe shell.  The following
+          change to the top-level Kconfig file seems to work around these
+          problems:
+  
+          config APPSDIR
+              string
+          -   option env="APPSDIR"
+          +   default "../apps"

+kconfig.bat
+-----------
+
+  Recent versions of NuttX support building NuttX from a native Windows
+  CMD.exe shell.  But kconfig-frontends is a Linux tool and is not yet
+  available in the pure CMD.exe environment.  At this point, there are
+  only a few options for the Windows user (see the top-level README.txt
+  file).
+
+  You can, with some effort, run the the Cygwin mconf tool directly
+  in the CMD.exe shell.  In this case, you do not have to modify the
+  .config file, but there are other complexities:  You need to
+  temporarily set the Cgywin directories in the PATH variable and
+  then run mconf outside of the Make system.
+
+  kconfig.bat is a Windows batch file at tools/kconfig.bat that automates
+  these steps.  It is used from the top-level NuttX directory like:
+
+    tools/kconfig menuconfig
+
+  NOTE: There is an currently an issue with accessing DOS environment
+  variables from the Cygwin mconf running in the CMD.exe shell.  The
+  following change to the top-level Kconfig file seems to work around
+  these problems:
+  
+     config APPSDIR
+          string
+     -   option env="APPSDIR"
