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