+.SH NAME
+9wm \- \*(85-like Window Manager for X
+.SH SYNOPSIS
+.B 9wm
+[
+.B \-grey
+] [
+.B \-version
+] [
+.B \-font
+.I fname
+] [
+.B \-term
+.I termprog
+] [
+.BR exit | restart
+]
+.SH DESCRIPTION
+.I 9wm
+is a window manager for X which attempts to emulate the window management
+policies of Plan 9's
+.I \*(85
+window manager.
+.PP
+The
+.B \-grey
+option makes the background light grey, as does \*(85.
+Use this option for maximum authenticity.
+.B \-font
+.I fname
+sets the font in
+.IR 9wm 's
+menu to
+.IR fname ,
+overriding the default.
+.B \-term
+.I termprog
+specifies an alternative program to run when the
+.I New
+menu item is selected.
+.B \-version
+prints the current version on standard error, then exits.
+.PP
+To make
+.I 9wm
+exit, you have to run
+.B "9wm exit"
+on the command line. There is no ``exit'' menu item.
+.PP
+.I 9wm
+is click-to-type: it has a notion of the current window,
+which is usually on top, and always has its border darkened.
+Characters typed at the keyboard go to the current window,
+and mouse clicks outside the current window are swallowed up
+by
+.IR 9wm .
+To make another window the current one, click on it with button 1.
+Unlike other X window managers, 9wm implements `mouse focus': mouse events
+are sent only to the current window.
+.PP
+A menu of window operations is available by pressing button 3
+outside the current window.
+The first of these,
+.IR New ,
+attempts to spawn a
+.I 9term
+process (or
+.I xterm
+if
+.I 9term
+is not available).
+The new
+.I 9term
+will request that its outline be swept using button 3
+of the mouse, by changing the cursor.
+.RI ( xterm
+defaults to a fixed size, and thus wants to be dragged; pressing
+button 3 places it.)
+.PP
+The next four menu items are
+.IR Reshape ,
+.IR Move ,
+.IR Delete ,
+and
+.IR Hide .
+All of the operations change the cursor into a target, prompting the user
+to click button 3 on one of the windows to select it for the operation.
+At this stage, clicking button 1 or 2 will abort the operation.
+Otherwise, if the operation was
+.IR Resize ,
+the user is prompted to sweep out the new outline with button 3.
+If it was
+.IR Move ,
+the user should keep the button held down after the initial click that selected
+the window, and drag the window to the right place before releasing.
+In either case, button 1 or 2 will abort the operation.
+.PP
+If the
+.I Delete
+operation is selected, the window will be deleted when the button is released.
+This typically kills the client that owns the window.
+The
+.I Hide
+operation just makes the window invisible. While hidden, the window's
+name appears on the bottom of the button 3 menu. Selecting that item
+brings the window back (unhides it).
+This operation replaces the iconification feature provided by other
+window managers.
+.SH BUGS
+Is not completely compatible with \*(85.
+.PP
+There is a currently a compiled-in limit of 32 hidden windows.
+.SH "SEE ALSO"
+.IR 9term (1),
+.IR xterm (1).

+This is David Hogan's 9wm updated to behave more like
+Plan 9's rio. Since I cannot get approval for the changes
+and I'd prefer not to resort to patches, I have renamed it "rio".
+
+Current incompatibilities that would be nice to fix:
+
+- Rio uses X11 fonts for the menu, and there aren't any good ones!
+I'm tempted to hard-code the Plan 9 default font bitmap.
+
+- The command-line options should be made more like Plan 9.
+
+- Should work out a protocol between 9term and rio so that:
+ * 9term can tell rio to blue its border during hold mode
+ * rio can tell 9term to fade its text when it loses focus
+ * rio can tell 9term to unfade its text when it regains focus
+
+- Should change window focus on b2/b3 clicks and then
+ pass along the click event to the now-focused window.
+
+- Should change 9term to redirect b3 clicks to rio so that rio
+ can put up the usual b3 menu.
+
+The original README is below.

+
+What is 9wm?
+============
+
+9wm is an X window manager which attempts to emulate the Plan 9 window
+manager 8-1/2 as far as possible within the constraints imposed by X.
+It provides a simple yet comfortable user interface, without garish
+decorations or title-bars. Or icons. And it's click-to-type. This
+will not appeal to everybody, but if you're not put off yet then read
+on. (And don't knock it until you've tried it.)
+
+One major difference between 9wm and 8-1/2 is that the latter provides
+windows of text with a typescript interface, and doesn't need to run a
+separate program to emulate a terminal. 9wm, as an X window manager,
+does require a separate program. For better 8-1/2 emulation, you should
+obtain Matthew Farrow's "9term" program (ftp://ftp.cs.su.oz.au/matty/unicode),
+version 1.6 or later (earlier versions don't cooperate with 9wm in
+implementing "hold mode"). Of course, you can run xterm under 9wm as well.
+
+What is 9wm not?
+================
+
+9wm is not a virtual window manager. It is not customisable to any
+great extent. It is not large and unwieldy, and doesn't use the X
+toolkit. Requests to make it any of these things will be silently
+ignored (or flamed if I have had a bad day :-) If you want tvtwm
+or mwm, you know where to get them...
+
+Where do I get it?
+==================
+
+The latest version of 9wm is held at ftp://ftp.cs.su.oz.au/dhog/9wm
+
+Author
+======
+
+9wm was written by David Hogan (dhog@cs.su.oz.au), a postgraduate
+student at the Basser Department of Computer Science, University
+of Sydney (http://www.cs.su.oz.au/~dhog/).
+
+Licence
+=======
+
+ 9wm is free software, and is Copyright (c) 1994-1996 by David Hogan.
+ Permission is granted to all sentient beings to use this software,
+ to make copies of it, and to distribute those copies, provided
+ that:
+
+ (1) the copyright and licence notices are left intact
+ (2) the recipients are aware that it is free software
+ (3) any unapproved changes in functionality are either
+ (i) only distributed as patches
+ or (ii) distributed as a new program which is not called 9wm
+ and whose documentation gives credit where it is due
+ (4) the author is not held responsible for any defects
+ or shortcomings in the software, or damages caused by it.
+
+ There is no warranty for this software. Have a nice day.
+
+How do I compile/install it?
+============================
+
+Assuming your system is correctly configured, you should only need to
+run xmkmf to generate the Makefile, and then run make or make install.
+make install.man should copy the manpage (9wm.man) to the appropriate
+directory.
+
+If the make fails, complaining that the function _XShapeQueryExtension
+does not exist, try removing the "-DSHAPE" from the Imakefile, and
+run xmkmf and make again.
+
+If you don't have imake, or it is misconfigured, or you would prefer
+not to use it, try copying the file "Makefile.no-imake" to "Makefile",
+then edit the definitions in this Makefile to suit your system. This
+may require defining suitable compilation flags for your system
+(normally imake does this for you). For instance, on AIX you must
+include "-DBSD_INCLUDES" in CFLAGS.
+
+How do I use it?
+================
+
+See the manual page for details. You should probably read the
+man page for 9term as well.
+
+What if I find a bug?
+=====================
+
+Please mail all bug reports to 9wm-bugs@plan9.cs.su.oz.au, so
+that I can incorporate fixes into the next release. If you can
+tell me how to fix it, all the better.
+
+Known Problems/Bugs
+===================
+
+9wm tries hard to emulate 8-1/2, but isn't 100% compatible. If
+you are an experienced 8-1/2 user, please be patient with it.
+
+One intentional difference between 9wm and 8-1/2 is in the behaviour
+of the menu when the last hidden item is unhidden. Under 8-1/2, when
+the menu is next used, it pops up with "New" selected. Under 9wm,
+the (new) last menu item will be selected. This is a feature. It
+may be confusing if you frequently switch between 9wm and 8-1/2.
+If you don't like this feature, email me for the one line fix.
+
+There have been some problems encountered when resizing 9term on
+some platforms. This turns out to be a problem in 9term (actually
+in libXg, to be precise). Newer versions of 9term should be
+immune to this, see matty@cs.su.oz.au if your 9term needs fixing.
+
+Some client programs do weird things. One of these is Frame Maker.
+It appears that if it has a modal dialog on the screen, then if any
+of its windows are current, all keypresses are redirected to the
+modal dialog. This is not 9wm's fault -- Frame Maker is doing this.
+
+Programs like Netscape Navigator like to put riddiculously long
+icon name properties on their windows, of the form "Netscape: blah blah".
+There is no way that I know of to stop netscape from doing this. For this
+reason, 9wm truncates labels at the first colon it finds. This keeps the
+button 3 menu from becoming excessively wide. Note that with same
+applications, you can use an iconName resource to set the label; this
+works well for "xman", whose default icon name of "Manual Browser"
+is a tad too long.

+Acknowledgements
+================
+
+Thanks to Rob Pike for writing the original 8-1/2 program (and
+before that, mux) which inspired the writing of 9wm.
+
+Thanks to John Mackin, whose gwm "wool code" for emulating mux
+was also an inspiration: I used it (and hacked it) until I got
+too frustrated with gwm's large memory requirements and lack of
+speed (sorry Colas!), and decided to write a dedicated program.
+
+Thanks to Matthew Farrow for writing 9term.
+
+A big thanks to Dave Edmondson for adding support for
+multi-screen displays.
