REM QUILL_DATA_DIR is only honored when the dev-build flag is on, and it must
REM live under your home directory. Defaulting it here keeps test data out of
REM the repo and out of your real install, so you can test source changes
REM without rebuilding. Override either var before calling this script.

REM assets that are not in the source tree (whisper.cpp, DECtalk, Piper under
