arbitrary bytes from the web server, without needing to download the entire
file.  This is particularly useful with large archives such as ZIP files and
ISO images when you only need to inspect their contents or extract specific
files.  Since the HTTP protocol itself has no notion of directories, only a
single file can be mounted.")
