any-dialog 1.0.0

# any-dialog yes/no question, rendered as a MessageBox under
# Windows PowerShell. Values arrive through ANYDIALOG_*
# environment variables, never as part of the script text.
# The answer is printed on stdout as the token "yes" or "no".
# A YesNo box cannot be dismissed without answering (Windows
# disables its close button), so there is no cancel path.
# Exit codes: 0 = answered, 2 = error (message printed on stderr).
