REM
REM Key technique: We cannot delete the project folder while
REM this batch script is running inside it. So we create a
REM temporary "deleter" script in %TEMP%, launch it in a new
REM window, then exit this script immediately. The deleter
REM waits for us to exit, then removes the entire folder.
