Add extra file into the rpm building process

i have the source-code of an application that supports adding python plugins. i have written a python script and want to build a custom rpm that by-default includes my script. So that i do not have to additionally add it after the rpm installation.

Now as far as i understand, there are two parts to this-

1. Adding the file to the source code.
2. Listing that file in the .spec file.

How do i know where to put the file in the source? How do i specify the path where i want my script to be copied? The spec file contains text like-

%if %{with_python}
%files python
%{_mandir}/man5/collectd-python*
%{_libdir}/%{name}/python.so

//Something like this?

// %{_libdir}/%{name}/gearman.py 
// %{_libdir}/%{name}/redis.py
%endif
