     "GNU Midnight Commander is a command-line file manager laid out in a
common two-pane format.  In addition to standard file management tasks such as
copying and moving, Midnight Commander also supports viewing the contents of
RPM package files and other archives and managing files on other computers via
FTP or FISH.  It also includes a powerful text editor for opening text
files.")
