-Tcl Mac OS X README
--------------------
-
-This is the README file for the Mac OS X/Darwin version of Tcl.
-
-
-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 Tcl on Mac OS X to the tracker:
-	http://core.tcl.tk/tcl/reportlist
-
-2. Using Tcl on Mac OS X
-------------------------
-
-- At a minimum, Mac OS X 10.3 is required to run Tcl.
-
-- Unless weak-linking is used, Tcl built on Mac OS X 10.x will not run on 10.y
-with y < x; on the other hand Tcl 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
-built on 10.x to run on any 10.y with x > y >= z (for a chosen z >= 2).
-
-- 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 framework:
-	Tcl.framework/Resources/Documentation/Reference/Tcl
-No nroff manpages are installed by default by the GNUmakefile.
-
-- The Tcl framework can be installed in any of the system's standard
-framework directories:
-	$HOME/Library/Frameworks /Library/Frameworks /System/Library/Frameworks
-
-
-3. Building Tcl on Mac OS X
----------------------------
-
-- At least Mac OS X 10.3 is required to build Tcl.
-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 is most easily built as a Mac OS X framework via GNUmakefile in tcl/macosx
-(see below for details), but can also be built with the standard unix configure
-and make buildsystem in tcl/unix as on any other unix platform (indeed, the
-GNUmakefile is just a wrapper around the unix buildsystem).
-The Mac OS X specific configure flags are --enable-framework and
---disable-corefoundation (which disables CF and notably reverts to the standard
-select based notifier).
-
-- It is also possible to build with the Xcode IDE via the projects in
-tcl/macosx, take care to use the project matching your DevTools and OS version:
-	Tcl.xcode: 		    for Xcode 3.1 on 10.5
-	Tcl.xcodeproj:		    for Xcode 3.2 on 10.6
-These have the following targets:
-	Tcl:			    calls through to tcl/macosx/GNUMakefile.
-	tcltest:		    static build of tcltest for debugging.
-	tests:			    build tcltest target and run tcl testsuite.
-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.
-	DebugNoFixAndContinue:      disable Fix & Continue.
-	DebugUnthreaded:	    disable threading.
-	DebugNoCF:		    disable corefoundation.
-	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 (Tcl.xcode) resp. 10.6 (Tcl.xcodeproj).
-The Xcode projects refer to the toplevel tcl source directory via the
-TCL_SRCROOT user build setting, by default this is set to the project-relative
-path '../../tcl', if your tcl source directory is named differently, e.g.
-'../../tcl8.6', you need to manually change the TCL_SRCROOT setting by editing
-your ${USER}.pbxuser file (located inside the Tcl.xcodeproj bundle directory)
-with a text editor.
-
-- To build universal binaries outside of the Xcode IDE, set CFLAGS as follows:
-	export CFLAGS="-arch i386 -arch x86_64 -arch ppc"
-This requires Mac OS X 10.4 and Xcode 2.4 (or Xcode 2.2 if -arch x86_64 is
-omitted, but _not_ Xcode 2.1) and will work on any architecture (on PowerPC
-Tiger you need to add "-isysroot /Developer/SDKs/MacOSX10.4u.sdk").
-Note that configure requires CFLAGS to contain a least one architecture that can
-be run on the build machine (i.e. ppc on G3/G4, ppc or ppc64 on G5, ppc or i386
-on Core and ppc, i386 or x86_64 on Core2/Xeon).
-Universal builds of Tcl TEA extensions are also possible with CFLAGS set as
-above, they will be [load]able by universal as well as thin binaries of Tcl.
-
-- To enable weak-linking, set the MACOSX_DEPLOYMENT_TARGET environment variable
-to the minimal OS version the binaries should be able to run on, e.g:
-	export MACOSX_DEPLOYMENT_TARGET=10.4
-This requires at least gcc 3.1; with gcc 4 or later, set/add to CFLAGS instead:
-	export CFLAGS="-mmacosx-version-min=10.4"
-Support for weak-linking was added with 8.4.14/8.5a5.
-
-Detailed Instructions for building with macosx/GNUmakefile
-----------------------------------------------------------
-
-- Unpack the Tcl source release archive.
-
-- The following instructions assume the Tcl source tree is named "tcl${ver}",
-(where ${ver} is a shell variable containing the Tcl version number e.g. '8.6').
-Setup this shell variable as follows:
-	ver="8.6"
-If you are building from CVS, omit this step (CVS source tree names usually do
-not contain a version number).
-
-- Setup environment variables as desired, e.g. for a universal build on 10.5:
-	CFLAGS="-arch i386 -arch x86_64 -arch ppc -mmacosx-version-min=10.5"
-	export CFLAGS
-
-- Change to the directory containing the Tcl source tree and build:
-	make -C tcl${ver}/macosx
-
-- Install Tcl onto the root volume (admin password required):
-	sudo make -C tcl${ver}/macosx install
-if you don't have an admin password, you can install into your home directory
-instead by passing an INSTALL_ROOT argument to make:
-	make -C tcl${ver}/macosx install INSTALL_ROOT="${HOME}/"
-
-- The default GNUmakefile targets will build _both_ debug and optimized versions
-of the Tcl framework with the standard convention of naming the debug library
-Tcl.framework/Tcl_debug.
-This allows switching to the debug libraries at runtime by setting
-	export DYLD_IMAGE_SUFFIX=_debug
-(c.f. man dyld for more details)
-
-If you only want to build and install the debug or optimized build, use the
-'develop' or 'deploy' target variants of the GNUmakefile, respectively.
-For example, to build and install only the optimized versions:
-	make -C tcl${ver}/macosx deploy
-	sudo make -C tcl${ver}/macosx install-deploy
