Those packages that I created install correctly for me with current Portage.
Feel free to fix them if they don't install at all or if you think they need some improvement.
www-apps/rimgo might require proper logging and a SystemD service for non OpenRC users.
I used EGO_SUM instead of a vendor tarball because I've no way to host it but feel free to create one.
