I gathered that it does. I couldn't locate it, as it 
does not begin with ns or nsplugin, etc. That's why I 
started digging in /usr/lib.

So I understand. This is what I was after. I was 
concerned that not calling the proper program might 
bypass exactly this functionality, while yet leading 
me to believe it was, since the links in 
mozilla/plugins-wrapped are created.

Well, I didn't look at the code yet, a script, I 
presume.

When I ran mozilla-plugin-config as root, it seemed to 
be working correctly and links in plugins-wrapped are 
created, but it does give me a few errors:

Is this because these are excluded in 
/etc/sysconfig/nspluginwrapper?

Why are they excluded?

Must I exclude them?
