+# NuttX uses symbolic links to configure platform-specific directories into
+# the build system.  This works great except for when a Windows native
+# toolchain is used in a Cygwin environment.  In that case, symbolic
+# links do not work correctly when accessed from the Windows native toolchain;
+# rather, just look link files with the extension .lnk
+#
+# In this environment, the build system will work around this using this script
+# as a replacement for the 'ln' command.  This scrpt will simply copy the
+# directory into the expected positiion.
