-# This workflow is meant for development use and run only on demand.
-# It is customizable to select
-#   - Platforms
-#   - Toolchains
-#   - Branches (no need for core-* prefixes)
-#   - Tests
-# To run the workflow, select "Custom" on the left side in the GH Actions
-# page. Then click the Run workflow button on the right. This will display
-# a dropdown that allows customization as above.
-#
-# To run the workflow, you need to have permissions to the repository.
-# The simplest way is to clone the Tcl mirror on Github. However, that means
-# if you work in fossil, you have a potential 24-hour wait before the mirror
-# updates, which apart from nostalgia about the punched card batch processing
-# era, is not so convenient. My preference instead is to mirror the fossil
-# repository to Github via a local checkout on my system, do the work there
-# pushing to github and running this workflow to verify across platforms
-# and then committing back to the master fossil repository.
-#
-# Improvements to the workflow welcome.

+
+1. Introduction
+---------------
+Tcl provides a powerful platform for creating integration applications that
+tie together diverse applications, protocols, devices, and frameworks.
+When paired with the Tk toolkit, Tcl provides the fastest and most powerful
+way to create GUI applications that run on PCs, Unix, and Mac OS X.
+Tcl can also be used for a variety of web-related tasks and for creating
+powerful command languages for applications.
+
+Tcl is maintained, enhanced, and distributed freely by the Tcl community.
+The home for Tcl/Tk releases and bug/patch database is on SourceForge:
+
+	http://tcl.sourceforge.net/
+
+with the Tcl Developer Xchange hosted at:
+
+	http://www.tcl.tk/
+
+Tcl is a freely available open source package.  You can do virtually
+anything you like with it, such as modifying it, redistributing it,
+and selling it either in whole or in part.  See the file
+"license.terms" for complete information.
+
+2. Documentation
+----------------
+
+Extensive documentation is available at our website.
+The home page for this release, including new features, is
+	http://www.tcl.tk/software/tcltk/8.6.html
+
+Detailed release notes can be found at the file distributions page
+by clicking on the relevant version.
+	http://sourceforge.net/projects/tcl/files/
+
+Information about Tcl itself can be found at
+	http://www.tcl.tk/about/
+
+There have been many Tcl books on the market.  Many are mentioned in the Wiki:
+	http://wiki.tcl.tk/_/ref?N=25206
+
+To view the complete set of reference manual entries for Tcl 8.6 online,
+visit the URL:
+	http://www.tcl.tk/man/tcl8.6/
+
+2a. Unix Documentation
+----------------------
+
+The "doc" subdirectory in this release contains a complete set of
+reference manual entries for Tcl.  Files with extension ".1" are for
+programs (for example, tclsh.1); files with extension ".3" are for C
+library procedures; and files with extension ".n" describe Tcl
+commands.  The file "doc/Tcl.n" gives a quick summary of the Tcl
+language syntax.  To print any of the man pages on Unix, cd to the
+"doc" directory and invoke your favorite variant of troff using the
+normal -man macros, for example
+
+		ditroff -man Tcl.n
+
+to print Tcl.n.  If Tcl has been installed correctly and your "man" program
+supports it, you should be able to access the Tcl manual entries using the
+normal "man" mechanisms, such as
+
+		man Tcl
+
+2b. Windows Documentation
+-------------------------
+
+The "doc" subdirectory in this release contains a complete set of Windows
+help files for Tcl.  Once you install this Tcl release, a shortcut to the
+Windows help Tcl documentation will appear in the "Start" menu:
+
+	Start | Programs | Tcl | Tcl Help
+
+3. Compiling and installing Tcl
+-------------------------------
+
+There are brief notes in the unix/README, win/README, and macosx/README about
+compiling on these different platforms.  There is additional information
+about building Tcl from sources at
+
+	http://www.tcl.tk/doc/howto/compile.html
+
+4. Development tools
+---------------------------
+
+ActiveState produces a high quality set of commercial quality development
+tools that is available to accelerate your Tcl application development.
+Tcl Dev Kit builds on the earlier TclPro toolset and provides a debugger,
+static code checker, single-file wrapping utility, bytecode compiler and
+more.  More information can be found at
+
+	http://www.ActiveState.com/Tcl
+
+5. Tcl newsgroup
+----------------
+
+There is a USENET news group, "comp.lang.tcl", intended for the exchange of
+information about Tcl, Tk, and related applications.  The newsgroup is a
+great place to ask general information questions.  For bug reports, please
+see the "Support and bug fixes" section below.
+
+6. Tcl'ers Wiki
+---------------
+
+A Wiki-based open community site covering all aspects of Tcl/Tk is at:
+
+	http://wiki.tcl.tk/
+
+It is dedicated to the Tcl programming language and its extensions.  A
+wealth of useful information can be found there.  It contains code
+snippets, references to papers, books, and FAQs, as well as pointers to
+development tools, extensions, and applications.  You can also recommend
+additional URLs by editing the wiki yourself.
+
+7. Mailing lists
+----------------
+
+Several mailing lists are hosted at SourceForge to discuss development or
+use issues (like Macintosh and Windows topics).  For more information and
+to subscribe, visit:
+
+	http://sourceforge.net/projects/tcl/
+
+and go to the Mailing Lists page.
+
+8. Support and Training
+------------------------
+
+We are very interested in receiving bug reports, patches, and suggestions
+for improvements.  We prefer that you send this information to us via the
+bug form at SourceForge, rather than emailing us directly.  The bug
+database is at:
+
+	http://tcl.sourceforge.net/
+
+The bug form was designed to give uniform structure to bug reports as
+well as to solicit enough information to minimize followup questions.
+
+We will log and follow-up on each bug, although we cannot promise a
+specific turn-around time.  Enhancements, reported via the Feature
+Requests form at the same web site, may take longer and may not happen
+at all unless there is widespread support for them (we're trying to
+slow the rate at which Tcl/Tk turns into a kitchen sink).  It's very
+difficult to make incompatible changes to Tcl/Tk at this point, due to
+the size of the installed base.
+
+The Tcl community is too large for us to provide much individual support
+for users.  If you need help we suggest that you post questions to
+comp.lang.tcl.  We read the newsgroup and will attempt to answer esoteric
+questions for which no one else is likely to know the answer.  In addition,
+see the following Web site for links to other organizations that offer
+Tcl/Tk training:
+
+	http://wiki.tcl.tk/training
+
+9. Tracking Development
+-----------------------
+
+Tcl is developed in public.  To keep an eye on how Tcl is changing, see
+	http://core.tcl.tk/
+
+10. Thank You
+-------------
+
+We'd like to express our thanks to the Tcl community for all the
+helpful suggestions, bug reports, and patches we have received.
+Tcl/Tk has improved vastly and will continue to do so with your help.

-# New commands and options
-
- [New options `-backslashes`, `-commands` and `-variables` for `subst` command](https://core.tcl-lang.org/tips/doc/trunk/tip/712.md)
- [New command `unicode` for Unicode normalization](https://core.tcl-lang.org/tips/doc/trunk/tip/726.md)
- [New `timer` command, switch to monotonic clock and microsecond resolution](https://core.tcl-lang.org/tips/doc/trunk/tip/723.md)
- [Remove `expr` behavior from `lseq`](https://core.tcl-lang.org/tips/doc/trunk/tip/746.md) *Incompatibility*
- [File paths are now treated as case-insensitive on MacOS](https://core.tcl-lang.org/tcl/tktview/e6ca0b1b) *Incompatibility*
- New command `tcl::registry` as a synonym for the `registry` command without needing
-the registry package to be loaded. The registry module is now part of the core
-Tcl DLL in all build configurations.
- [New `lfilter` command for selecting items from a list](https://core.tcl-lang.org/tips/doc/trunk/tip/735.md)
- [Many new functions from C99](https://core.tcl-lang.org/tips/doc/trunk/tip/745.md), specifically: `acosh()`, `asinh()`, `atanh()`, `cbrt()`, `copysign()`, `dim()`,  `erf()`, `erfc()`, `exp2()`, `expm1()`, `fma()`, `gamma()`, `ldexp()`, `lgamma()`, `log1p()`, `log2()`, `logb()`, `nextafter()`, `remainder()`, `signbit()`, and `trunc()`, and (for functions that return multiple values in their C99 API) the commands: `divmod`, `frexp`, `modf`, and `remquo`. (See [this page](https://en.cppreference.com/w/c/numeric/math.html) for more information about these functions; the Tcl functions are _intentionally_ only thin wrappers around the functions in the C99 standard.)

+- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
  necessary to get gzprintf working correctly. This is done by configure.

 - zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
  other compilers. Use "make test" to check your compiler.

-
-In most cases the usual
-
-    cmake -S . -B build -D CMAKE_BUILD_TYPE=Release
-
-will create everything you need, however if you want something off default you can adjust several options fit your needs.
-Every option is list below (excluding the cmake-standard options), they can be set via cmake-gui or on cmdline with
-
-    -D<option>=ON/OFF
-
-## ZLIB-options with defaults ##
-
-    ZLIB_BUILD_TESTING=ON -- Enable Zlib Examples as tests
-
-    ZLIB_BUILD_SHARED=ON -- Enable building zlib shared library
-
-    ZLIB_BUILD_STATIC=ON -- Enable building zlib static library
-
-    ZLIB_BUILD_MINIZIP=ON -- Enable building libminizip contrib library
-
-If this option is turned on, additional options are available from minizip (see below)
-
-    ZLIB_INSTALL=ON -- Enable installation of zlib
-
-    ZLIB_PREFIX=OFF -- prefix for all types and library functions, see zconf.h.in
-
-This option is only on windows available and may/will be turned off and removed somewhen in the future.
-If you rely cmake for finding and using zlib, this can be turned off, as `zlib1.dll` will never be used.

-
-## Using the libs ##
-
-To pull in what you need it's enough to just write
-
-    find_package(ZLIB CONFIG)
-
-or
-
-    find_package(minizip CONFIG)
-
-in your CMakeLists.txt, however it is advised to specify what you really want via:
-
-    find_package(ZLIB CONFIG COMPONENTS shared static REQUIRED)
-
-or
-
-    find_package(minizip CONFIG COMPONENTS shared static REQUIRED)
-
-As it's possible to only build the shared or the static lib, you can make sure that everything you need
-is found. If no COMPONENTS are requested, everything needs to be found to satisfy your request. If the
-libraries are optional in you project, you can omit the REQUIRED and check yourself if the targets you
-want to link against are created.
-
-When you search for minizip, it will search zlib for you, so only one of both is needed.
-
-## Imported targets ##
-
-When found the following targets are created for you:
-
-    ZLIB::ZLIB and ZLIB::ZLIBSTATIC -- for zlib
-    MINIZIP::minizip and MINIZIP::minizipstatic -- for minizip

+        ZLIB version 1.2.7 for AS400 installation instructions
+
+I) From an AS400 *SAVF file:
+
+1)      Unpacking archive to an AS400 save file
+
+On the AS400:
+
+_       Create the ZLIB AS400 library:
+
+        CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
+
+_       Create a work save file, for example:
+
+                CRTSAVF FILE(ZLIB/ZLIBSAVF)
+
+On a PC connected to the target AS400:
+
+_       Unpack the save file image to a PC file "ZLIBSAVF"
+_       Upload this file into the save file on the AS400, for example
+                using ftp in BINARY mode.
+
+
+2)      Populating the ZLIB AS400 source library
+
+On the AS400:
+
+_       Extract the saved objects into the ZLIB AS400 library using:
+
+RSTOBJ OBJ(*ALL) SAVLIB(ZLIB) DEV(*SAVF) SAVF(ZLIB/ZLIBSAVF) RSTLIB(ZLIB)
+
+
+3)      Customize installation:
+
+_       Edit CL member ZLIB/TOOLS(COMPILE) and change parameters if needed,
+                according to the comments.
+
+_       Compile this member with:
+
+        CRTCLPGM PGM(ZLIB/COMPILE) SRCFILE(ZLIB/TOOLS) SRCMBR(COMPILE)
+
+
+4)      Compile and generate the service program:
+
+_       This can now be done by executing:
+
+        CALL PGM(ZLIB/COMPILE)
+
+
+
+II) From the original source distribution:
+
+1)      On the AS400, create the source library:
+
+        CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
+
+2)      Create the source files:
+
+        CRTSRCPF FILE(ZLIB/SOURCES) RCDLEN(112) TEXT('ZLIB library modules')
+        CRTSRCPF FILE(ZLIB/H)       RCDLEN(112) TEXT('ZLIB library includes')
+        CRTSRCPF FILE(ZLIB/TOOLS)   RCDLEN(112) TEXT('ZLIB library control utilities')

+Notes:  For AS400 ILE RPG programmers, a /copy member defining the ZLIB
+                API prototypes for ILE RPG can be found in ZLIB/H(ZLIB.INC).
+                Please read comments in this member for more information.
+
+        Remember that most foreign textual data are ASCII coded: this
+                implementation does not handle conversion from/to ASCII, so
+                text data code conversions must be done explicitely.
+
+        Mainly for the reason above, always open zipped files in binary mode.

+This is a patched version of zlib, modified to use
+Pentium-Pro-optimized assembly code in the deflation algorithm. The
+files changed/added by this patch are:
+
+README.686
+match.S
+
+The speedup that this patch provides varies, depending on whether the
+compiler used to build the original version of zlib falls afoul of the
+PPro's speed traps. My own tests show a speedup of around 10-20% at
+the default compression level, and 20-30% using -9, against a version
+compiled using gcc 2.7.2.3. Your mileage may vary.
+
+Note that this code has been tailored for the PPro/PII in particular,
+and will not perform particuarly well on a Pentium.
+
+If you are using an assembler other than GNU as, you will have to
+translate match.S to use your assembler's syntax. (Have fun.)
+
+Brian Raiter
+breadbox@muppetlabs.com
+April, 1998
+
+
+Added for zlib 1.1.3:
+
+The patches come from
+http://www.muppetlabs.com/~breadbox/software/assembly.html
+
+To compile zlib with this asm file, copy match.S to the zlib directory
+then do:
+
+CFLAGS="-O3 -DASMV" ./configure
+make OBJA=match.o
+
+
+Update:
+
+I've been ignoring these assembly routines for years, believing that
+gcc's generated code had caught up with it sometime around gcc 2.95
+and the major rearchitecting of the Pentium 4. However, I recently
+learned that, despite what I believed, this code still has some life
+in it. On the Pentium 4 and AMD64 chips, it continues to run about 8%
+faster than the code produced by gcc 4.1.
+
+In acknowledgement of its continuing usefulness, I've altered the
+license to match that of the rest of zlib. Share and Enjoy!
