# Test wheel.
# The file has the following contents:
#   hello.pyd
#   hello/hello.py
#   hello/__init__.py
#   test-1.0.data/data/hello.dat
#   test-1.0.data/headers/hello.dat
#   test-1.0.data/scripts/hello.sh
#   test-1.0.dist-info/WHEEL
#   test-1.0.dist-info/METADATA
#   test-1.0.dist-info/RECORD
# The root is PLATLIB
# So, some in PLATLIB, and one in each of DATA, HEADERS and SCRIPTS.
