-files being archived are themselves plain text files.
-.It Cm shardump
-This format is similar to shar but encodes binary files so that the result
-will be a plain text file regardless of the file contents.
-It also includes additional shell commands that attempt to reproduce as

-Extended attributes, file flags, and other extended
-security information cannot be stored.
-.It
