+Tcl/Tk Mac OS X README
+----------------------
+
+This is the README file for the Mac OS X/Darwin version of Tcl/Tk.
+
+1. Where to go for support
+--------------------------
+
+- The tcl-mac mailing list on sourceforge is the best place to ask questions
+specific to Tcl & Tk on Mac OS X:
+	http://lists.sourceforge.net/lists/listinfo/tcl-mac
+(this page also has a link to searchable archives of the list, please check them
+before asking on the list, many questions have already been answered).
+
+- For general Tcl/Tk questions, the newsgroup comp.lang.tcl is your best bet:
+	http://groups.google.com/group/comp.lang.tcl/
+
+- The Tcl'ers Wiki also has many pages dealing with Tcl & Tk on Mac OS X, see
+	http://wiki.tcl.tk/_/ref?N=3753
+	http://wiki.tcl.tk/_/ref?N=8361
+
+- Please report bugs with Tk on Mac OS X to the tracker:
+	http://core.tcl.tk/tk/reportlist
+
+2. Using Tcl/Tk on Mac OS X
+---------------------------
+
+- There are two versions of Tk available on Mac OS X: TkAqua using the native
+aqua widgets and look&feel, and TkX11 using the traditional unix X11 wigets.
+TkX11 requires an X11 server to be installed, such as Apple's X11 (which is
+available as an optional or default install on recent Mac OS X).
+TkAqua and TkX11 can be distinguished at runtime via [tk windowingsystem].
+
+- At a minimum, Mac OS X 10.3 is required to run Tcl and TkX11.
+TkAqua requires Mac OS X 10.5 or later (starting with the Cocoa-based Tk 8.5.7).
+
+- Unless weak-linking is used, Tcl/Tk built on Mac OS X 10.x will not run on
+10.y with y < x; on the other hand Tcl/Tk built on 10.y will always run on 10.x
+with y <= x (but without any of the fixes and optimizations that would be
+available in a binary built on 10.x).
+Weak-linking is available on OS X 10.2 or later, it additionally allows Tcl/Tk
+built on 10.x to run on any 10.y with x > y >= z (for a chosen z >= 2).
+
+- Wish checks the Resources/Scripts directory in its application bundle for a
+file called AppMain.tcl, if found it is used as the startup script and the
+Scripts folder is added to the auto_path. This can be used to emulate the old
+OS9 TclTk droplets.
+
+- If standard input is a special file of zero length (e.g. /dev/null), Wish
+brings up the Tk console window at startup. This is the case when double
+clicking Wish in the Finder (or using 'open Wish.app' from the Terminal).
+
+- Tcl extensions can be installed in any of:
+	$HOME/Library/Tcl /Library/Tcl /System/Library/Tcl
+	$HOME/Library/Frameworks /Library/Frameworks /System/Library/Frameworks
+	(searched in that order).
+Given a potential package directory $pkg, Tcl on OSX checks for the file
+$pkg/Resources/Scripts/pkgIndex.tcl as well as the usual $pkg/pkgIndex.tcl.
+This allows building extensions as frameworks with all script files contained in
+the Resources/Scripts directory of the framework.
+
+- [load]able binary extensions can linked as either ordinary shared libraries
+(.dylib) or as MachO bundles (since 8.4.10/8.5a3); bundles have the advantage
+that they are [load]ed more efficiently from a tcl VFS (no temporary copy to the
+native filesystem required), and prior to Mac OS X 10.5, only bundles can be
+[unload]ed.
+
+- The 'deploy' target of macosx/GNUmakefile installs the html manpages into the
+standard documentation location in the Tcl/Tk frameworks:
+	Tcl.framework/Resources/Documentation/Reference/Tcl
+	Tk.framework/Resources/Documentation/Reference/Tk
+No nroff manpages are installed by default by the GNUmakefile.
+
+- The Tcl and Tk frameworks can be installed in any of the system's standard
+framework directories:
+	$HOME/Library/Frameworks /Library/Frameworks /System/Library/Frameworks
+
+- ${prefix}/bin/wish8.x is a script that calls a copy of 'Wish' contained in
+	Tk.framework/Resources
+
+- if 'Wish' is started from the Finder or via 'open', $argv may contain a
+"-psn_XXXX" argument. This is the process serial number, you may need to filter
+it out for cross platform compatibility of your scripts.
+
+- the env array is different when Wish is started from the Finder (i.e. via
+LaunchServices) than when it (or tclsh) is invoked from the Terminal, in
+particular PATH may not be what you expect. (Wish started by LaunchServices
+inherits loginwindow's environment variables, which are essentially those set in
+$HOME/.MacOSX/environment.plist, and are unrelated to those set in your shell).
+
+- TkAqua drawing is antialiased by default, but (outline) linewidth can be used
+to control whether a line/shape is drawn antialiased. The antialiasing threshold
+is 0 by default (i.e. antialias everything), it can be changed by setting
+	set tk::mac::CGAntialiasLimit <limit>
+in your script before drawing, in which case lines (or shapes with outlines)
+thinner than <limit> pixels will not be antialiased.
+
+- Text antialiasing by default uses the standard OS antialising settings.
+Setting the global variable '::tk::mac::antialiasedtext' allows to control text
+antialiasing from Tcl: a value of 1 enables AA, 0 disables AA and -1 restores
+the default behaviour of respecting the OS settings.
+
+- Scrollbars: There are two scrollbar variants in Aqua, normal & small. The
+normal scrollbar has a small dimension of 15, the small variant 11.
+Access to the small variant was added in Tk 8.4.2.
+
+- The default metrics of native buttons, radiobuttons, checkboxes and
+menubuttons in the Cocoa-based Tk 8.5.7 and later preserve compatibility with
+the older Carbon-based implementation, you can turn off the compatibility
+metrics to get more native-looking spacing by setting:
+	set tk::mac::useCompatibilityMetrics 0
+
+- TkAqua provides access to native OS X images via the Tk native bitmap facility
+(including any image file readable by NSImage). A native bitmap name is
+interpreted as follows (in order):
+    - predefined builtin 32x32 icon name (stop, caution, document, etc)
+    - name defined by [tk::mac::iconBitmap]
+    - NSImage named image name
+    - NSImage url string
+    - 4-char OSType of IconServices icon
+the syntax of [tk::mac::iconBitmap] is as follows:
+	tk::mac::iconBitmap name width height -kind value
+where -kind is one of
+    -file	    icon of file at given path
+    -fileType	    icon of given file type
+    -osType	    icon of given 4-char OSType file type
+    -systemType	    icon for given IconServices 4-char OSType
+    -namedImage	    named NSImage for given name
+    -imageFile	    image at given path
+This support was added with the Cocoa-based Tk 8.5.7.
+
+- TkAqua cursor names are interpred as follows (in order):
+    - standard or platform-specific Tk cursor name (c.f. cursors.n)
+    - @path to any image file readable by NSImage
+    - NSImage named image name
+Support for the latter two was added with the Cocoa-based Tk 8.5.7.
+
+- The standard Tk dialog commands [tk_getOpenFile], [tk_chooseDirectory],
+[tk_getSaveFile] and [tk_messageBox] all take an additional optional -command
+parameter on TkAqua. If it is present, the given command prefix is evaluated at
+the global level when the dialog closes, with the dialog command's result
+appended (the dialog command itself returning an emtpy result). If the -parent
+option is also present, the dialog is configured as a modeless (window-modal)
+sheet attached to the parent window and the dialog command returns immediately.
+Support for -command was added with the Cocoa-based Tk 8.5.7.
+
+- The TkAqua-specific [tk::mac::standardAboutPanel] command brings the standard
+Cocoa about panel to the front, with all its information filled in from your
+application bundle files (i.e. standard about panel with no options specified).
+See Apple Technote TN2179 and the AppKit documentation for -[NSApplication
+orderFrontStandardAboutPanelWithOptions:] for details on the Info.plist keys and
+app bundle files used by the about panel.
+This support was added with the Cocoa-based Tk 8.5.7.
+
+- TkAqua has three special menu names that give access to the standard
+Application, Window and Help menus, see menu.n for details.
+By default, the platform-specific standard Help menu item "YourApp Help" peforms
+the default Cocoa action of showing the Help Book configured in the
+application's Info.plist (or displaying an alert if no Help Book is set). This
+action can be customized by defining a procedure named [tk::mac::ShowHelp], if
+present, this procedure is invoked instead by the standard Help menu item.
+Support for the Window menu and [tk::mac::ShowHelp] was added with the
+Cocoa-based Tk 8.5.7.
+
+- The TkAqua-specific command [tk::unsupported::MacWindowStyle style] is used to
+get and set Mac OS X-specific toplevel window class and attributes. Note that
+the window class and many attributes have to be set before the window is first
+mapped for the change to have any effect.
+The command has the following syntax:
+	tk::unsupported::MacWindowStyle style window ?class? ?attributes?
+The 2 argument form returns a list of the current class and attributes for the
+given window. The 3 argument form sets the class for the given window using the
+default attributes for that class. The 4 argument form sets the class and the
+list of attributes for the given window.
+Window class names:
+    document, modal, floating, utility, toolbar, simple, help, overlay
+Window attribute names:
+    standardDocument, standardFloating, resizable, fullZoom, horizontalZoom,
+    verticalZoom, closeBox, collapseBox, toolbarButton, sideTitlebar,
+    noTitleBar, unifiedTitleAndToolbar, metal, hud, noShadow, doesNotCycle,
+    noActivates, hideOnSuspend, inWindowMenu, ignoreClicks, doesNotHide,
+    canJoinAllSpaces, moveToActiveSpace, nonActivating, black, dark, light,
+    gray, red, green, blue, cyan, yellow, magenta, orange, purple,
+    brown, clear, opacity
+
+Note that not all attributes are valid for all window classes.
+Support for the 3 argument form was added with the Cocoa-based Tk 8.5.7, at the
+same time support for some legacy Carbon-specific classes and attributes was
+removed (they are still accepted by the command but no longer have any effect).
+
+The color window attributes (black, dark, red, etc.) and the "opacity" allow  one to set the background and opacity of a textured ("metal") window. This allows a Tk window to implement a window without the dividing line between the titlebar and the rest of the window, or the "unified toolbar" effect, which is increasingly standard in Mac applications. An example:
+
+toplevel .f
+tk::unsupported::MacWindowStyle style .f document {metal light opaque closeBox collapseBox resizable standardDocument }
+
+pack [label .f.f -bg  #ababab -text "This is a textured window\nwith opacity and a gray background\nsimilar to other Mac applications"] -fill both -expand yes
+
+The color attributes correspond to system-defined NSColor constants (e.g., red is [NSColor redColor]. The "light" and "dark" attributes correspond to lightGrayColor and darkGrayColor, respectively (because of the way the attributes are parsed, using "lightgray" and "darkgray" would cause a conflict with the core "gray" attribute).
+
+Below are the corresponding hex and/or Tk-defined colors that can be used from Tk widgets to match the NSColor-based attributes:
+
+black	#000000
+dark	#545454
+light	#ababab
+white	#ffffff
+gray	#7f7f7f
+red 	#ff0000
+green	#00ff00
+blue	#0000ff
+cyan	#00ffff
+yellow	#ffff00
+magenta	#ff00ff
+orange	#ff8000
+purple 	#800080
+brown	#996633
+clear	systemTransparent
+
+- The Cocoa-based TkAqua can be distinguished from the older Carbon-based
+version via the [winfo server .] command, example output on Mac OS X 10.5.7:
+    Cocoa-based:	CG409.3 Apple AppKit GC 949.46 Mac OS X 1057
+    Carbon-based:	QD10R30 Apple 1057
+
+- If you want to use Remote Debugging with Xcode, you need to set the
+environment variable XCNOSTDIN to 1 in the Executable editor for Wish. That will
+cause us to force closing stdin & stdout.  Otherwise, given how Xcode launches
+Wish remotely, they will be left open and then Wish & gdb will fight for stdin.
+
+
+3. Building Tcl/Tk on Mac OS X
+------------------------------
+
+- At least Mac OS X 10.3 is required to build Tcl and TkX11, and Mac OS X 10.5
+is required to build TkAqua.
+Apple's Xcode Developer Tools need to be installed (only the most recent version
+matching your OS release is supported), the Xcode installer is available on Mac
+OS X install media or may be present in /Applications/Installers on Macs that
+came with OS X preinstalled. The most recent version can always be downloaded
+from the ADC website http://connect.apple.com (free ADC membership required).
+
+- Tcl/Tk are most easily built as Mac OS X frameworks via GNUmakefile in
+tcl/macosx and tk/macosx (see below for details), but can also be built with the
+standard unix configure and make buildsystem in tcl/unix resp. tk/unix as on any
+other unix platform (indeed, the GNUmakefiles are just wrappers around the unix
+buildsystem).
+The Mac OS X specific configure flags are --enable-aqua, --enable-framework and
+--disable-corefoundation (which disables CF and notably reverts to the standard
+select based notifier). Note that --enable-aqua is incompatible with
+--disable-corefoundation (for both Tcl and Tk configure).
+
+- It is also possible to build with the Xcode IDE via the projects in
+tk/macosx, take care to use the project matching your DevTools and OS version:
+	Tk.xcode: 		    for Xcode 3.1 on 10.5
+	Tk.xcodeproj:		    for Xcode 3.2 on 10.6
+These have the following targets:
+	Tk:			    calls through to tk/macosx/GNUMakefile,
+				    requires a corresponding build of the Tcl
+				    target of tcl/macosx/Tcl.xcode.
+	tktest:			    static build of TkAqua tktest for debugging.
+	tktest-X11:		    static build of TkX11 tktest for debugging.
+The following build configurations are available:
+	Debug:			    debug build for the active architecture,
+				    with Fix & Continue enabled.
+	Debug clang:		    use clang compiler.
+	Debug llvm-gcc:		    use llvm-gcc compiler.
+	Debug gcc40:		    use gcc 4.0 compiler.
+	DebugNoGC:		    disable Objective-C garbage collection.
+	DebugNoFixAndContinue:      disable Fix & Continue.
+	DebugUnthreaded:	    disable threading.
+	DebugNoCF:		    disable corefoundation (X11 only).
+	DebugNoCFUnthreaded:	    disable corefoundation an threading.
+	DebugMemCompile:	    enable memory and bytecode debugging.
+	DebugLeaks:		    define PURIFY.
+	DebugGCov:		    enable generation of gcov data files.
+	Debug64bit:		    configure with --enable-64bit (requires
+				    building on a 64bit capable processor).
+	Release:		    release build for the active architecture.
+	ReleaseUniversal:	    32/64-bit universal build.
+	ReleaseUniversal clang:	    use clang compiler.
+	ReleaseUniversal llvm-gcc:  use llvm-gcc compiler.
+	ReleaseUniversal gcc40:	    use gcc 4.0 compiler.
+	ReleaseUniversal10.5SDK:    build against the 10.5 SDK (with 10.5
+				    deployment target).
+	Note that the non-SDK configurations have their deployment target set to
+	10.5 (Tk.xcode) resp. 10.6 (Tk.xcodeproj).
+The Xcode projects refer to the toplevel tcl and tk source directories via the
+the TCL_SRCROOT and TK_SRCROOT user build settings, by default these are set to
+the project-relative paths '../../tcl' and '../../tk', if your source
+directories are named differently, e.g. '../../tcl8.6' and '../../tk8.6', you
+need to manually change the TCL_SRCROOT and TK_SRCROOT settings by editing your
+${USER}.pbxuser file (located inside the Tk.xcodeproj bundle directory) with a
+text editor.
+
+- To build universal binaries outside of the Xcode IDE, set CFLAGS as follows:
+	export CFLAGS="-arch i386 -arch x86_64 -arch ppc"
+This requires Mac OS X 10.4 and Xcode 2.4 (or Xcode 2.2 if -arch x86_64 is
+omitted, but _not_ Xcode 2.1) and will work on any architecture (on PowerPC
+Tiger you need to add "-isysroot /Developer/SDKs/MacOSX10.4u.sdk").
+Note that configure requires CFLAGS to contain a least one architecture that can
+be run on the build machine (i.e. ppc on G3/G4, ppc or ppc64 on G5, ppc or i386
+on Core and ppc, i386 or x86_64 on Core2/Xeon).
+Universal builds of Tcl TEA extensions are also possible with CFLAGS set as
+above, they will be [load]able by universal as well as thin binaries of Tcl.
+
+- To enable weak-linking, set the MACOSX_DEPLOYMENT_TARGET environment variable
+to the minimal OS version the binaries should be able to run on, e.g:
+	export MACOSX_DEPLOYMENT_TARGET=10.4
+This requires at least gcc 3.1; with gcc 4 or later, set/add to CFLAGS instead:
+	export CFLAGS="-mmacosx-version-min=10.4"
+Support for weak-linking was added with 8.4.14/8.5a5.
+
+Detailed Instructions for building with macosx/GNUmakefile
+----------------------------------------------------------
+
+- Unpack the Tcl and Tk source release archives and place the tcl and tk source
+trees in a common parent directory.
+[ If you don't want have the two source trees in one directory, you'll need to ]
+[ create the following symbolic link for the build to work as setup by default ]
+[      ln -fs /path_to_tcl/build /path_to_tk/build			       ]
+[ (where /path_to_{tcl,tk} is the directory containing the tcl resp. tk tree)  ]
+[ or you can pass an argument of BUILD_DIR=/somewhere to the tcl and tk make.  ]
+
+- The following instructions assume the Tcl and Tk source trees are named
+"tcl${ver}" and "tk${ver}" (where ${ver} is a shell variable containing the
+Tcl/Tk version number, e.g. '8.6').
+Setup this shell variable as follows:
+	ver="8.6"
+If you are building from CVS, omit this step (CVS source tree names usually do
+not contain a version number).
+
+- Setup environment variables as desired, e.g. for a universal build on 10.5:
+	CFLAGS="-arch i386 -arch x86_64 -arch ppc -mmacosx-version-min=10.5"
+	export CFLAGS
+
+- Change to the directory containing the Tcl and Tk source trees and build:
+	make -C tcl${ver}/macosx
+	make -C tk${ver}/macosx
+
+- Install Tcl and Tk onto the root volume (admin password required):
+	sudo make -C tcl${ver}/macosx install
+	sudo make -C tk${ver}/macosx  install
+if you don't have an admin password, you can install into your home directory
+instead by passing an INSTALL_ROOT argument to make:
+	make -C tcl${ver}/macosx install INSTALL_ROOT="${HOME}/"
+	make -C tk${ver}/macosx  install INSTALL_ROOT="${HOME}/"
+
+- The default GNUmakefile targets will build _both_ debug and optimized versions
+of the Tcl and Tk frameworks with the standard convention of naming the debug
+library Tcl.framework/Tcl_debug resp. Tk.framework/Tk_debug.
+This allows switching to the debug libraries at runtime by setting
+	export DYLD_IMAGE_SUFFIX=_debug
+(c.f. man dyld for more details)
+
+If you only want to build and install the debug or optimized build, use the
+'develop' or 'deploy' target variants of the GNUmakefile, respectively.
+For example, to build and install only the optimized versions:
+	make -C tcl${ver}/macosx deploy
+	make -C tk${ver}/macosx deploy
+	sudo make -C tcl${ver}/macosx install-deploy
+	sudo make -C tk${ver}/macosx  install-deploy
+
+- The GNUmakefile can also build a version of Wish.app that has the Tcl and Tk
+frameworks embedded in its application package. This allows for standalone
+deployment of the application with no installation required, e.g. from read-only
+media. To build & install in this manner, use the 'embedded' variants of
+the GNUmakefile targets.
+For example, to build a standalone 'Wish.app' in ./emb/Applications/Utilities:
+	make -C tcl${ver}/macosx embedded
+	make -C tk${ver}/macosx embedded
+	sudo make -C tcl${ver}/macosx install-embedded INSTALL_ROOT=`pwd`/emb/
+	sudo make -C tk${ver}/macosx  install-embedded INSTALL_ROOT=`pwd`/emb/
+Notes:
+  * if you've already built standard TclTkAqua, building embedded does not
+  require any new compiling or linking, so you can skip the first two makes.
+  (making relinking unnecessary was added with 8.4.2)
+  * the embedded frameworks include only optimized builds and no documentation.
+  * the standalone Wish has the directory Wish.app/Contents/lib in its
+  auto_path. Thus you can place tcl extensions in this directory (i.e. embed
+  them in the app package) and load them with [package require].
+
+- It is possible to build Tk against an installed Tcl.framework; but you will
+still need a tcl sourcetree in the location specified in TCL_SRC_DIR in
+Tcl.framework/tclConfig.sh. Also, linking with Tcl.framework has to work exactly
+as indicated in TCL_LIB_SPEC in Tcl.framework/tclConfig.sh.
+If you used non-default install locations for Tcl.framework, specify them as
+make overrides to the tk/macosx GNUmakefile, e.g.
+	make -C tk${ver}/macosx \
+	    TCL_FRAMEWORK_DIR=$HOME/Library/Frameworks TCLSH_DIR=$HOME/usr/bin
+	sudo make -C tk${ver}/macosx install \
+	    TCL_FRAMEWORK_DIR=$HOME/Library/Frameworks TCLSH_DIR=$HOME/usr/bin
+The Makefile variables TCL_FRAMEWORK_DIR and TCLSH_DIR were added with Tk 8.4.3.
+
+4. About the event loop in Tk for Mac OSX
+-----------------------------------------
+
+The main program in a typical OSX application looks like this (see *)
+
+    void NSApplicationMain(int argc, char *argv[]) {
+        [NSApplication sharedApplication];
+        [NSBundle loadNibNamed:@"myMain" owner:NSApp];
+        [NSApp run];
+    }
+
+The run method implements the event loop for the application.  There
+are three key steps in the run method.  First it calls
+[NSApp finishLaunching], which creates the bouncing application icon
+and does other mysterious things. Second it creates an
+NSAutoreleasePool.  Third, it starts an event loop which drains the
+NSAutoreleasePool every time the queue is empty, and replaces the
+drained pool with a new one.  This third step is essential to
+preventing memory leaks, since the internal methods of Appkit objects
+all assume that an autorelease pool is in scope and will be drained
+when the event processing cycle ends.
+
+Mac OSX Tk does not call the [NSApp run] method at all.  Instead it
+uses the event loop built in to Tk.  So we must take care to replicate
+the important features of the method ourselves.  Here is how this
+works in outline.
+
+We add a private NSAUtoreleasePool* property to our subclass of
+NSApplication.  (The subclass is called TKApplication but can be
+referenced with the global variable NSApp).  The TkpInit
+function calls [NSApp _setup] which initializes this property by
+creating an NSAutoreleasePool. A bit later on, TkpInit calls
+[NSAPP _setupEventLoop] which in turn calls the
+[NSApp finishLaunching] method.
+
+Each time that Tcl processes an event in its queue, it calls a
+platform specific function which, in the case of Mac OSX, is named
+TkMacOSXEventsCheckProc.  In the unix implementations of Tk, including
+the Mac OSX version, this function collects events from an "event
+source", and transfers them to the Tcl event queue.  In Mac OSX the
+event source is the NSApplication event queue.  Each NSEvent is
+converted to a Tcl event which is added to the Tcl event queue.  The
+NSEvent is also passed to [NSApp sendevent], which sends the event on
+to the application's NSWindows, which send it to their NSViews, etc.
+Since the CheckProc function gets called for every Tk event, it is an
+appropriate place to drain the main NSAutoreleasePool and replace it
+with a new pool.  This is done by calling the method
+[NSApp _resetAutoreleasePool], where _resetAutoreleasePool is a method
+which we define for the subclass TKApplication.
+
+One minor caveat is that there are several steps of the Tk
+initialization which precede the call to TkpInit.  Notably, the font
+package is initialized first.  Since there is no NSAUtoreleasePool in
+scope prior to calling TkpInit, the functions called in these
+preliminary stages need to create and drain their own
+NSAutoreleasePools whenever they call methods of Appkit objects
+(e.g. NSFont).

+ * tkMacOSXSend.c --
+ *
+ *	This file provides procedures that implement the "send" command,
+ *	allowing commands to be passed from interpreter to interpreter. This
+ *	current implementation for the Mac has most functionality stubed out.
+ *
+ *	The current plan, which we have not had time to implement, is for the
+ *	first Wish app to create a gestalt of type 'WIsH'. This gestalt will
+ *	point to a table, in system memory, of Tk apps. Each Tk app, when it
+ *	starts up, will register their name, and process ID, in this table.
+ *	This will allow us to implement "tk appname".
+ *
+ *	Then the send command will look up the process id of the target app in
+ *	this table, and send an AppleEvent to that process. The AppleEvent
+ *	handler is much like the do script handler, except that you have to
+ *	specify the name of the tk app as well, since there may be many
+ *	interps in one wish app, and you need to send it to the right one.
+ *
+ *	Implementing this has been on our list of things to do, but what with
+ *	the demise of Tcl at Sun, and the lack of resources at Scriptics it
+ *	may not get done for awhile. So this sketch is offered for the brave
+ *	to attempt if they need the functionality...

+ * The information below is used for communication between processes during

+ * command is appended to the comm property of the communication window
+ * associated with the interp's process. Similarly, when a result is returned
+ * from a sent command, it is also appended to the comm property.
+ *
+ * Each command and each result takes the form of ASCII text. For a command,
+ * the text consists of a zero character followed by several null-terminated
+ * ASCII strings. The first string consists of the single letter "c".
+ * Subsequent strings have the form "option value" where the following options
+ * are supported:
+ *
+ * -r commWindow serial
+ *
+ *	This option means that a response should be sent to the window whose X
+ *	identifier is "commWindow" (in hex), and the response should be
+ *	identified with the serial number given by "serial" (in decimal). If
+ *	this option isn't specified then the send is asynchronous and no
+ *	response is sent.
+ *
+ * -n name
+ *
+ *	"Name" gives the name of the application for which the command is
+ *	intended. This option must be present.
+ *
+ * -s script
+ *
+ *	"Script" is the script to be executed. This option must be present.
+ *
+ * The options may appear in any order. The -n and -s options must be present,
+ * but -r may be omitted for asynchronous RPCs. For compatibility with future
+ * releases that may add new features, there may be additional options
+ * present; as long as they start with a "-" character, they will be ignored.
+ *
+ *
+ * A result also consists of a zero character followed by several null-
+ * terminated ASCII strings. The first string consists of the single letter
+ * "r". Subsequent strings have the form "option value" where the following
+ * options are supported:
+ *
+ * -s serial
+ *
+ *	Identifies the command for which this is the result. It is the same as
+ *	the "serial" field from the -s option in the command. This option must
+ *	be present.
+ *
+ * -c code
+ *
+ *	"Code" is the completion code for the script, in decimal. If the code
+ *	is omitted it defaults to TCL_OK.
+ *
+ * -r result
+ *
+ *	"Result" is the result string for the script, which may be either a
+ *	result or an error message. If this field is omitted then it defaults
+ *	to an empty string.
+ *
+ * -i errorInfo
+ *
+ *	"ErrorInfo" gives a string with which to initialize the errorInfo
+ *	variable. This option may be omitted; it is ignored unless the
+ *	completion code is TCL_ERROR.
+ *
+ * -e errorCode
+ *
+ *	"ErrorCode" gives a string with with to initialize the errorCode
+ *	variable. This option may be omitted; it is ignored unless the
+ *	completion code is TCL_ERROR.
+ *
+ * Options may appear in any order, and only the -s option must be present. As

+ * Apple XHIG Tab View Specifications:
+ *
+ * Control sizes: Tab views are available in regular, small, and mini sizes.
+ * The tab height is fixed for each size, but you control the size of the pane
+ * area. The tab heights for each size are listed below:
+ *  - Regular size: 20 pixels.
+ *  - Small: 17 pixels.
+ *  - Mini: 15 pixels.
+ *
+ * Label spacing and fonts: The tab labels should be in a font that’s
+ * proportional to the size of the tab view control. In addition, the label
+ * should be placed so that there are equal margins of space before and after
+ * it. The guidelines below provide the specifications you should use for tab
+ * labels:
+ *  - Regular size: System font. Center in tab, leaving 12 pixels on each side.
+ *  - Small: Small system font. Center in tab, leaving 10 pixels on each side.
+ *  - Mini: Mini system font. Center in tab, leaving 8 pixels on each side.
+ *
+ * Control spacing: Whether you decide to inset a tab view in a window or
+ * extend its edges to the window sides and bottom, you should place the top
+ * edge of the tab view 12 or 14 pixels below the bottom edge of the title bar
+ * (or toolbar, if there is one). If you choose to inset a tab view in a
+ * window, you should leave a margin of 20 pixels between the sides and bottom
+ * of the tab view and the sides and bottom of the window (although 16 pixels
+ * is also an acceptable margin-width). If you need to provide controls below
+ * the tab view, leave enough space below the tab view so the controls are 20
+ * pixels above the bottom edge of the window and 12 pixels between the tab
+ * view and the controls.
+ * If you choose to extend the tab view sides and bottom so that they meet the
+ * window sides and bottom, you should leave a margin of at least 20 pixels
+ * between the content in the tab view and the tab-view edges.
