 Wander around a filesystem executing commands of your choice on selected

+files and directories.
+
+.SH THE BIG PICTURE
+Graphical User Interfaces (GUIs) are a blessing and a curse. On the
+one hand, they make it easy to learn and use a computer system.  On
+the other, they are a real inconvenience to experienced users who are 
+touch typists.  Taking hands off the keyboard to use the mouse
+can really slow down a good typist.
+
+Nowhere is this more apparent than in filesystem browsers.  In one
+corner we have the GUI variants like \'Konqueror\' and \'Microsoft
+Windows Explorer\'.  These are very easy to use but you pretty much
+need the mouse in your hand to do anything useful.  In the other
+corner are the text-based file browsers like \'List\', \'Norton
+Commander\', and \'Midnight Commander\'.  These are really efficient
+to use, but have limited functionality and generally do not operate
+very well on
+.B groups
+of things.
+
+Both of these approaches also suffer from the well-known
+interface problem of "What You See Is
+.B All
+You Get" - Each program has a predefined set of commands and the user
+cannot easily extend these with their own, new commands.
+
+\'twander\' is a new approach to the filesystem navigation problem which
+embraces the best of both the GUI-based approach and the text-based
+approach.  It also provides a rich mechanism whereby each user can
+easily define their own command set and thereby customize the program
+as they see fit.  This is done with a number of key features:
+
+
+.TP
+1)
+The
+.B Navigation
+of the filesystem is graphical - you can use the mouse to select files,
+directories, or to change directories.  However, each major filesystem
+navigational feature is also doubled on the keyboard (using Control keys)
+so you can move around and select things without ever touching the mouse.
+
+.TP
+2)
+\'twander\' also supports a number of
+.B navigation shortcuts.
+It provides single control-key access to changing directories, moving
+to the previous directory, moving up one directory level, moving to
+any previously visited directory, (de)selecting any or all
+files/directories in the current view, and escaping to the operating
+system to run a command.  Many (but not all) of these features are
+also doubled via GUI/mouse operations.
+
+.TP
+3)
+There are
+.B no
+built-in file or directory commands.  All commands which manipulate
+the files or directories selected during navigation are user-defined.
+This command definition is done in an external configuration file
+using a simple but powerful command macro language.  This means that
+that the command set of the program can easily be changed or expanded
+without having to release a new version of \'twander\' every time.
+Better still, every different user can have their own command set
+defined in a way that suits their style of working.  Best of all,
+commands can be invoked either graphically (with a mouse click) or via
+a single keypress to minimize moving your hands off the keyboard.
+
+.TP
+4)
+Because \'twander\' is written in Python using Tkinter, the same
+program runs essentially identically on many Unix-style and Win32
+systems.  The only thing that may need to be changed across these
+various platforms are the command definitions in the configuration
+file.  You only need to learn one interface (and the commands you've
+defined) across all the different systems you use.
+
+.P
+The consquence of all this is that \'twander\' is an extremely
+powerful and highly customizable filesystem navigator.  Once
+learned, both navigation and command execution are lightning-fast
+(or at least, as fast as your machine can go ;) while minimizing
+dependency on the mouse.

 .SH SYNOPSIS
 twander [-bcdfhnqrstwvxy] [startdir]
-.SH DESCRIPTION
-\'twander\' is a GUI-based file tree navigation tool.  It lets you "wander"
-through your file system at will.  Unlike other similar programs,
-.B YOU
-define what features or commands are available to manipulate selected
-files.  You do this via a configuration file.  This gives you the
-convenience of a GUI-driven file navigator with the flexibility of
-defining almost any kind of command you'd like at your disposal.
