	what is the reason for the use of "eval" in the following?  just to
	strip off the comments in /etc/ifconfig.IF?  or there's some other use?
	variables in $args will not be expanded due to singlequote around $args.

	actually, I was confused by the fact
		nwid ''
	does not work in ifconfig.wi0, as '' itseif (not the empty string)
	will be passed as the SSID.  


                        elif [ -f /etc/ifconfig.$int ]; then
                                echo -n " $int"
                                (while read args; do
                                        if [ -n "`eval echo '$args'`" ] ; then
                                                ifconfig $int $args
                                done) < /etc/ifconfig.$int
