wireshark/summary.c
Gerald Combs 92802883a6 Change the "--enable-setuid-install" option to install dumpcap and TShark
setuid instead of Wireshark.  Remove the "DANGEROUS" notices, but leave it
disabled by default.  Whine if the user runs Wireshark or TShark as root.
Add a preference to disable the whining.  Add a "setuid-root" script that
can be used to switch dumpcap and TShark's setuid-ness on and off for
development and testing.  Update the release notes and README.packaging.
