"4Pane is a multi-pane, detailed-list file manager for
Linux. It is designed to be fully-featured without bloat, and aims
for speed rather than visual effects. In addition to standard file
manager things, it offers multiple undo and redo of most operations
(including deletions), archive management including 'virtual
browsing' inside archives, multiple renaming/duplication of files,
a terminal emulator and user-defined tools."
