echo Options:
echo     /b     - Deletes the binary output directory.
echo     /p     - Deletes the repo-local nuget package directory.
echo     /c     - Deletes the user-local nuget package cache.
echo     /t     - Deletes the tools directory.
echo     /s     - Deletes the untracked files under src directory (git clean src -xdf).
echo     /e     - Kills and/or stops the processes that are still running, for example VBCSCompiler.exe
echo     /all   - Combines all of the above.
echo.
echo If no option is specified then clean.cmd /b is implied.
