[Distutils] setup('postinstall'='my.py')

[Leonardo Rochael Almeida]

Hi,

The thing about setup.py is that it only runs at "build time".

However, it looks like you want to generate a unique id at every install.

Since you mentioned a windows installer, consider adding some code to the
installer itself so that it calls an entry point in your library to
generate this unique id at that moment.

Sorry, there isn't any support in setuptools to do this from within
setup.py itself.

Regards,

Leo
