OpenBSD Operating System

Saw this and its so awesome seeing the BSD shine and improve. There is not a lot as linux but steadily i hope these are shared more and more.

Anyway here is one i recently saw uploaded 2d games are still a banger. Openbsd Gaming

I'm looking for a tool, that allows me to open different files with an appropriate tool automatically. I've got xdg-open available on my system, but it seems quite cumbersome to configure. Thus I was looking for an alternative.

The mailcap format seems to be somewhat common and easy to use, but pkg_info -Q mailcap returned no results. Is there any tool that supports mailcap files in the ports, that I missed?

If there is none: Is there a good alternative, that you use?
