[SailfishDevel] prefered way to build rpm package for a project written in python/pyotherside?

[Boris Pohler]

Hi,
I wrote my first little program using python/pyotherside. I develop
directly on the jolla-device (no sdk) and would like to build a rpm
package to distribute to openrepos (and later to harbour, if python is
accepted). What is the prefered (easiest) way?

P.S.: My desktop-distribution is Archlinux.
