26 * 2009-09-19: jyoung
27 *
28 * New capinfos features
29 *
30 * Continue processing additional files after
31 * a wiretap open failure. The new -C option
32 * reverts to capinfos' original behavior which
33 * is to cancel any further file processing at
34 * first file open failure.
35 *
36 * Change the behavior of how the default display
37 * of all infos is initiated. This gets rid of a
38 * special post getopt() argument count test.
39 *
40 * Add new table output format (with related options)
41 * This feature allows outputting the various infos
42 * into a tab delimited text file, or to a comma
43 * separated variables file (*.csv) instead of the
44 * original "long" format.
45 *
46 * 2011-04-05: wmeier
47 * behaviour changed: Upon exit capinfos will return
48 * an error status if an error occurred at any
49 * point during "continuous" file processing.
50 * (Previously a success status was always
51 * returned if the -C option was not used).
