"""
Check that scons --help is working.

We need this manual check because the original 'scons.bat' from
scons win-py36 3.0.0 package would crash the interpreter (see #2).

Unfortunately, calling `scons.bat --help` will crash the interpreter
and surprisingly still return 0 exit code, which would make the
build succeed.

This script then calls `scons --help` and ensures the correct
output is returned.
