# When launching the bundle, the executable target (i.e. MDANSE) modify the python that is shipped with the bundle (si.e. package path, dylib dependencies ...)

# In our case we also want the user to be able to start directly python without launching the bundle executable (e.g. to run scripts in command line) which is the reason
# why we have to modify the python executable appropriately with the following commands
