Changes for version 1.1:

1. Add SIGTERM (kill) to signals that are handled.

2. Support -a "*" to analyze all packets.  When * is specified, if
a time limit is specified, it applies to analyzing as well as 
processing.

3. Fixed some bugs in the parser, and added checks for problems due
to bad streams

4. Analyzing as well as processing can be interrupted and display
partial results.

5. Minor improvements in stream listing text.  Also, the list is now
sorted by stream number.

6. Added status output and options.

7. Added -b option to begin reading a disk file at a specified
   offset.
