+Tcl 8.0p1 for Macintosh

+SCCS: @(#) README 1.30 97/11/20 22:01:16
+
+1. Introduction
+---------------
+
+This is the README file for the Macintosh version of the Tcl
+scripting language. The file consists of information specific
+to the Macintosh version of Tcl. For more general information
+please read the README file in the main Tcl directory.
+
+2. What's new?
+--------------
+
+The main new feature is the Tcl compilier. You should certainly
+notice the speed improvements. Any problems are probably
+generic rather than Mac specific. If you have questions or
+comments about the compilier feel free to forward them to the
+author of the compilier: Brian Lewis <btlewis@eng.sun.com>.
+Several things were fixed/changed since the a1 release so be
+sure to check this out.
+
+The largest incompatible change on the Mac is the removal of the
+following commands: "rm", "rmdir", "mkdir", "mv" and "cp". These
+commands were never really supported and their functionality is
+superceded by the file command.
+
+I've also added in a new "AppleScript" command. This was contributed
+by Jim Ingham who is a new member of the Tcl group. It's very cool.
+The command isn't actually in the core - you need to do a "package
+require Tclapplescript" to get access to it. This code is officially
+unsupported and will change in the next release. However, the core
+functionality is there and is stable enough to use. Documentation
+can be found in "AppleScript.html" in the mac subdirectory.
+
+The resource command has also been rewacked. You can now read and
+write any Mac resource. Tcl now has the new (and VERY COOL) binary
+command that will allow you to pack and unpack the resources into
+useful Tcl code. We will eventually provide Tcl libraries for
+accessing the most common resources.
+
+See the main Tcl README for other features new to Tcl 8.0.
+
+3. Mac specific features
+------------------------
+
+There are several features or enhancements in Tcl that are unique to
+the Macintosh version of Tcl. Here is a list of those features and
+pointers to where you can find more information about the feature.
+
+* The "resource" command allows you manipulate Macintosh resources.
+ A complete man page is available for this command.
+
+* The Mac version of the "source" command has an option to source from
+ a Macintosh resource. Check the man page from the source command
+ for details.
+
+* The only command NOT available on the Mac is the exec command.
+ However, we include a Mac only package called Tclapplescript that
+ provides access to Mac's AppleScript system. This command is still
+ under design & construction. Documentatin can be found in the mac
+ subdirectory in a file called "AppleScript.html".
+
+* The env variable on the Macintosh works rather differently than on
+ Windows or UNIX platforms. Check out the tclvars man page for
+ details.
+
+* The command "file volumes" returns the available volumes on your
+ Macintosh. Check out the file command for details.
+
+* The command "file attributes" has the Mac specific options of
+ -creator and -type which allow you to query and set the Macintosh
+ creator and type codes for Mac files. See file man page for details.
+
+* We have added a template for creating a Background-only Tcl application.
+ So you can use Tcl as a faceless server process. For more details, see
+ the file background.doc.
+
+If you are writing cross platform code but would still like to use
+some of these Mac specific commands, please remember to use the
+tcl_platform variable to special case your code.
+
+4. The Distribution
+-------------------
+
+Macintosh Tcl is distributed in three different forms. This
+should make it easier to only download what you need. The
+packages are as follows:
+
+mactk8.0.1.sea.hqx
+
+ This distribution is a "binary" only release. It contains an
+ installer program that will install a 68k, PowerPC, or Fat
+ version of the "Tcl Shell" and "Wish" applications. In addition,
+ it installs the Tcl & Tk libraries in the Extensions folder inside
+ your System Folder.
+
+mactcltk-full-8.0.1.sea.hqx
+
+ This release contains the full release of Tcl and Tk for the
+ Macintosh plus the More Files packages which Macintosh Tcl and Tk
+ rely on.
+
+mactcl-source-8.0.1.sea.hqx
+
+ This release contains the complete source for Tcl 8.0. In
+ addition, Metrowerks CodeWarrior libraries and project files
+ are included. However, you must already have the More Files
+ package to compile this code.
+
+5. Documentation
+----------------
+
+The "html" subdirectory contains reference documentation in
+in the HTML format. You may also find these pages at:
+
+ http://sunscript.sun.com/man/tcl8.0/contents.html
+
+Other documentation and sample Tcl scripts can be found at
+the Tcl ftp site:
+
+ ftp://ftp.neosoft.com/tcl/
+
+The internet news group comp.lang.tcl is also a valuable
+source of information about Tcl. A mailing list is also
+available (see below).
+
+6. Compiling Tcl
+----------------
+
+In order to compile Macintosh Tcl you must have the
+following items:
+
+ CodeWarrior Pro 1
+ Mac Tcl 8.0 (source)
+ More Files 1.4.3
+
+There are two sets of project files included with the package. The ones
+we use for the release are for CodeWarrior Pro 1, and are not compatible
+with CodeWarrior Gold release 11 and earlier. We have included the files
+for earlier versions of CodeWarrior in the folder tcl8.0:mac:CW11 Projects,
+but they are unsupported, and a little out of date.
+
+As of Tcl8.0p2, the code will also build under CW Pro 2. The only
+change that needs to be made is that float.mac.c should be replaced by
+float.c in the MacTcl MSL project file.
+
+However, there seems to be a bug in the CFM68K Linker in CW Pro 2,
+which renders the CFM68K Version under CW Pro 2 very unstable. I am
+working with MetroWerks to resolve this issue. The PPC version is
+fine, as is the Traditional 68K Shell. But if you need to use the
+CFM68K, then you must stay with CW Pro 1 for now.
+
+The project files included with the Mac Tcl source should work
+fine. The only thing you may need to update are the access paths.
+Unfortunantly, it's somewhat common for the project files to become
+slightly corrupted. The most common problem is that the "Prefix file"
+found in the "C/C++ Preference" panel is incorrect. This should be
+set to MW_TclHeaderPPC, MW_TclHeader68K or MW_TclHeaderCFM68K.
+
+To build the fat version of TclShell, open the project file "TclShells.¼",
+select the "TclShell" target, and build. All of the associated binaries will
+be built automoatically. There are also targets for building static 68K
+and Power PC builds, for building a CFM 68K build, and for building a
+shared library Power PC only build.
+
+Special notes:
+
+* There is a small bug in More Files 1.4.3. Also you should not use
+ MoreFiles 1.4.4 - 1.4.6. Look in the file named morefiles.doc for
+ more details.
+
+* You may not have the libmoto library which will cause a compile
+ error. You don't REALLY need it - it can be removed. Look at the
+ file libmoto.doc for more details.
+
+* Check out the file bugs.doc for information about known bugs.
+
+If you have comments or Bug reports send them to:
