+specially formatted path under @file{~/.avfs} is accessed, the daemon will provide
+listings and content access on the fly.  The canonical form of virtual path is:
+[basepath]#handler[options][:parameters][/internalpath].  Example paths:
+@itemize
+@item ~/.avfs/home/user/archive.tar.gz#ugz#utar/path/file
+@item ~/.avfs/#http:localhost|some|path
+@end itemize
+@code{emacs-dired-hacks} has @code{dired-avfs} module which enables seamless
+integration with @code{avfs}.")
