Comment:

 Branch: fallback-to-python
 Repository: https://github.com/teor2345/chutney.git
 Changes:
   * If $PYTHON isn't set:
     * Use "command" to check for python2, and use it if it exists
     * Use "command" to check for python, and use it if it exists
     * (Skip python3, it doesn't work due to #16904)
   * If neither works, use the original default of python2
