If we consider the approach 'in conjunction with', is the following
adequately robust?
$ source app_setup.sh

#File: app_setup.sh
# -. shell-script .-
# Assume we can figure out some basic version of a python interpreter:
#  standalone executable
#  embedded within another application, providing basic libpython.a
features
#
$PYTHON sniffEnvWithComplexLogic.py 'shCompatibleEnvSettings.txt'
source shCompatibleEnvSettings.txt
