// Note: When maintaining tar files with ark, the user should be
// aware that these options have been improved (IMHO). When you append a file
// to a tarchive, tar does not check if the file exists already, and just
// tacks the new one on the end. ark deletes the old one.
// When you update a file that exists in a tarchive, it does check if
// it exists, but once again, it creates a duplicate at the end (only if
// the file is newer though). ark deletes the old one in this case as well.
//
// Basically, tar files are great for creating and extracting, but
// not especially for maintaining. The original purpose of a tar was of
// course, for tape backups, so this is not so surprising!      -Emily
