+/*
+ * 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).
