 WARNING: this project contains shell scripts, which CANNOT BE RUN on Windows
 without being translated first.
 WORKAROUND: for now, please remove your assets & plugins having shell scripts
 in their build phases, or translate them to batch scripts and call them in a
 pre-packaging script (or ignore this warning if the scripts are non-critical)
