[Distutils] setuptools and bdist_rpm

[Jon Nelson]

I'm new to setuptools and I'm hoping to have a few questions answered. I
also have some observations that may be useful, but that can come later.

1. why does setuptools bdist_rpm use
   --single-version-externally-managed?

2. is it possible to have setuptools write dependency information not
just to requires.txt but also to setup.cfg so that RPM will be aware of
the dependencies?

3. This is more of a distutils question, but, what can be done about the
INSTALLED_FILES containing directories that aren't marked with %dir
(this causes two problems: /all/ directories end up being created but
NOT owned by the RPM, and all files /under/ that directory get included,
which means they likely get included *twice* to to also being explicitly
included).

Sorry for the multi-issue email, I'm new at this.
