- # NuttX uses symbolic links to configure platform-specific directories into

- # 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
