+
+  winbuild:
+  --------
+
+    This is a version of the apps/example/ostest, but configure to build natively
+    in the Windows CMD shell.
+
+    NOTES:
+
+    1. The beginnings of a Windows native build are in place but still not full
+       usable as of this writing.  The windows native build logic is currently
+       separate and must be started by:
+
+        make -f Makefile.win
+
+      This build:
+
+        - Uses all Windows style paths
+        - Uses primarily Windows batch commands from cmd.exe, with
+        - A few extensions from GNUWin32 (or MSYS is you prefer)
+
+      In this build, you cannot use a Cygwin or MSYS shell. Rather the build must
+      be performed in a Windows CMD shell. Here is a better shell than than the
+      standard issue, CMD shell:  ConEmu which can be downloaded from:
+      http://code.google.com/p/conemu-maximus5/
+
+      Build Tools.  The build still relies on some Unix-like commands.  I use
+      the GNUWin32 tools that can be downloaded from http://gnuwin32.sourceforge.net/.
+      The MSYS tools are probably also a option but are likely lower performance
+      since they are based on Cygwin 1.3.
+
+      Host Compiler:  I use the MingGW compiler which can be downloaded from
+      http://www.mingw.org/.  If you are using GNUWin32, then it is recommended
+      the you not install the optional MSYS components as there may be conflicts.
