RPM Subpackages are very useful when you maintain the big project on the RHEL-kind Linux distro and you need to sparse the project into several differing packages (for instance - <main_package>, -libs, -devel, -debuginfo).

It would be convenient to do the same in a purely Pythonic projects (i mean to place something in setup.py and to obtain the output spec-file with a corresponding number of `%package <subpackage_name>` sections). I didn't manage to find the code that matches these purposes in the most up-to-date release of the distutils (/usr/lib64/python2.7/distutils/command/bdist_rpm.py). 

So I would ask to implement this feature. Also I can try to do it on my own in case if the community considers it as a good offer. Thank you.

Distutils is now deprecated (see PEP 632) and all tagged issues are being closed. From now until removal, only release blocking issues will be considered for distutils.

If this issue does not relate to distutils, please remove the component and reopen it. If you believe it still requires a fix, most likely the issue should be re-reported at https://github.com/pypa/setuptools
