Maybe I should look at this when I am not tired ... but I don't understand
how the security/stunnel gets the stunnel.conf-sample placed into the
/usr/pkg/etc/ directory.

It uses:
USE_PKGINSTALL=         yes
PKG_SYSCONFSUBDIR=      stunnel

But I don't see where it lists the file(s) to copy.

I am assuming this is because the admin should edit the example and put in
place themselves. (Maybe a MESSAGE?)

The +DEINSTALL has blank CONF_FILES (and SUPPORT_FILES). So I don't
see why it uses USE_PKGINSTALL.

Is this correct? And explanation?
