REM ============================================================
REM Wrapper for robocopy fixing the exit code issue
REM
REM Robocopy can return a non zero exit code even when there is
REM no error which can be problematic when integrated in a build
REM tool chain.
REM
REM Brocopy addresses that issue by calling robocopy but
REM returning 0 when successfull and 1 otherwise.
REM ============================================================

robocopy %*

REM Exit with 1 when errorlevel >= 8 and 0 otherwise
if ERRORLEVEL 8 GOTO error
exit /B 0

error:
exit /B 1
