calling external script during python package install

Question

I am interested in building a Windows distribution for my application.

The application requires that a number of environmental variables and/or registry entries be set for the software to function properly. Supposing I write a script 'set_vars.py' to create and set these entries, is there a way to call this script when the application is installed via

python setup.py install

From the documentation detailing 'setup.py', I did not see an obvious way to call pre-install or post-install scripts.

I would rather not have set_vars.py called from an init.py in the distribution because the variables only really need to be set up once at install time.

Does the accepted answer to How can I add post-install scripts to easy_install / setuptools / distutils? help? — martineau

Despite searching for some time, I completely missed those two previous questions/answers. The comment "You can add your subcommand to install.sub_commands, and pass the command into setup()." from the latter question may do the trick. Thank you very much. — cytochrome

Assuming you already have the needed action scripted, you could just --install-script=set_vars.py to your call to setup.py, or, even better (for convenience), add the option to your setup.cfg file.
