[Fedora-packaging] naming package as a library or tool

[Parag Nemade]

Hi,
   Sometimes I get confused how to handle naming of a package where
package itself provides a nodejs or python library and wrapper/tool to
use that library.
   We have guidelines where it says if source is library from npmjs or
pypi then we should prefix package with nodejs or python but how to
name when source contains both?
   What gets precedence? name them with prefixes or just by tool name
or library name?

Regards,
Parag.
