AVFS is a system, which enables all programs to look inside archived or
compressed files, or access remote files without recompiling the programs
or changing the kernel. At the moment it supports floppies, tar and gzip
files, zip, bzip2, ar and rar files, ftp sessions, http, webdav, rsh/rcp,
ssh/scp. Quite a few other handlers are implemented with the Midnight
Commander's external FS.

This requires: p7zip, unrar
