15 | *
16 | * New capinfos features
17 | *
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.
23 | *
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.
27 | *
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.
33 | *
34 | * 2011-04-05: wmeier
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).
