/*
* 2009-09-19: jyoung
*
* New capinfos features
*
* Continue processing additional files after
* a wiretap open failure. The new -C option
* reverts to capinfos' original behavior which
* is to cancel any further file processing at
* first file open failure.
*
* Change the behavior of how the default display
* of all infos is initiated. This gets rid of a
* special post getopt() argument count test.
*
* Add new table output format (with related options)
* This feature allows outputting the various infos
* into a tab delimited text file, or to a comma
* separated variables file (*.csv) instead of the
* original "long" format.
*
* 2011-04-05: wmeier
* behaviour changed: Upon exit capinfos will return
* an error status if an error occurred at any
* point during "continuous" file processing.
* (Previously a success status was always
* returned if the -C option was not used).
