 1) build zfs modules for Ubuntu 20.04 and 22.04 (~15m)
 2) 2x zloop test (~10m) + 2x sanity test (~25m)
-3) 4x functional testings in parts 1..4 (each ~1h)
+3) functional testings in parts 1..5 (each ~1h)
 4) cleanup and create summary
    - content of summary depends on the results of the steps

 # DESCRIPTION

 #   Note: Defines as a precious variable "PYTHON_VERSION". Don't override it
 #   in your configure.ac.
 #
+#   Note: this is a slightly modified version of the original AX_PYTHON_DEVEL

 #   This macro checks for Python and tries to get the include path to
