Yup.  The current plan is to loop thusly:

  for each list_archive_file:
    run "formail -s mime_extraction_tool < list_archive_file"
    for each extracted_file:
      file_type = `file -z extracted_file`
      if file_type == a_tar_file:
         tar -xf extracted_file
      else if file_type == a_gzipped_tar_file:
         tar -xzf extracted_file
      else if file_type == a_zip_file:
         unzip extracted_file
      for each raw_file `find extraction_dir -type f`:
        if raw_file is a valid Ethereal capture file:
           check for file name collision in target directory
           check for a duplicate file in target directory:
             move the file to the target directory

None of these steps should take too long to implement individually.  I
was hoping someone would come back with "you can do that with AMaViS in
about 60 seconds" so I could be lazy and not have to cobble it together
myself.
