+    (description "Vifm is a file manager providing a @command{vi}-like usage
+experience.  It has similar keybindings and modes (e.g. normal, command line,
+visual).  The interface uses ncurses, thus vifm can be used in text-only
+environments.  It supports a wide range of features, some of which are known
+from the @command{vi}-editor:
+@enumerate
+@item utf8 support
+@item user mappings (almost like in @code{vi})
+@item ranges in command
+@item line commands
+@item user defined commands (with support for ranges)
+@item registers
+@item operation undoing/redoing
+@item fuse file systems support
+@item trash
+@item multiple files renaming
+@item support of filename modifiers
+@item colorschemes support
+@item file name color according to file type
+@item path specific colorscheme customization
+@item bookmarks
+@item operation backgrounding
+@item customizable file viewers
+@item handy @code{less}-like preview mode
+@item filtering out and searching for files using regular expressions
+@item one or two panes view
+@end enumerate
+With the package comes a plugin to use vifm as a vim file selector.")
