-# 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.
