The project contains a start point for building your own AppImage in OBS. For more information please see https://github.com/probonopd/AppImageKit/wiki/Using-Open-Build-Service

The template here is using SUSE:SLE-12:SP4 as a base. So you may want to add further SLE 12 based repository pathes
to the "SLE_12_SP4" repositories to get access further packages.
