30 * New capinfos features
32 * Continue processing additional files after
33 * a wiretap open failure. The new -C option
34 * reverts to capinfos' original behavior which
35 * is to cancel any further file processing at
36 * first file open failure.
38 * Change the behavior of how the default display
39 * of all infos is initiated. This gets rid of a
40 * special post getopt() argument count test.
42 * Add new table output format (with related options)
43 * This feature allows outputting the various infos
44 * into a tab delimited text file, or to a comma
45 * separated variables file (*.csv) instead of the
46 * original "long" format.
49 * behaviour changed: Upon exit capinfos will return
50 * an error status if an error occurred at any
51 * point during "continuous" file processing.
52 * (Previously a success status was always
53 * returned if the -C option was not used).
