Author: eadler Date: Mon Dec 10 02:33:16 2012 New Revision: 244064 URL: http://svnweb.freebsd.org/changeset/base/244064 Log: MFC r243084: Add support for a -q flag. While here make the custom argument parsing use getopt instead of hacking on it more. This change also fixes the method of silencing the compiler warning about gfn being used uninitialized.
