+# 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.

+Release Tcl 9.1b1 arises from the check-in with tag `core-9-1-b1`.
+
+Highlighted differences between Tcl 9.1 and Tcl 9.0 are summarized below,
+with focus on changes important to programmers using the Tcl library and
+writing Tcl scripts.
+
+# 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.)
+- [New `switch` option `-integer` to compare values as integers](https://core.tcl-lang.org/tips/doc/trunk/tip/730.md)
+- [Reading and writing of child interpreter variables](https://core.tcl-lang.org/tips/doc/trunk/tip/728.md)
+- [Updated Tcl Bytecode opcodes](https://core.tcl-lang.org/tips/doc/trunk/tip/720.md)
+
+- New `tcltest::configure` option `-iterations` to control number of iterations of each test.
+
+# New public C API
+
+- [`Tcl_IsEmpty()` &mdash; checks if the string representation of a value would be the empty string](https://core.tcl-lang.org/tips/doc/trunk/tip/711.md)
+- [`Tcl_GetEncodingNameForUser()` &mdash; returns name of encoding from user settings](https://core.tcl-lang.org/tips/doc/trunk/tip/716.md)
+- [`Tcl_AttemptCreateHashEntry()` &mdash; version of `Tcl_CreateHashEntry()` that returns NULL instead of panic'ing on memory allocation errors](https://core.tcl-lang.org/tips/doc/trunk/tip/717.md)
+- [`Tcl_ListObjRange()`, `Tcl_ListObjRepeat()`, `Tcl_ListObjReverse()` &mdash; C API for new list operations](https://core.tcl-lang.org/tips/doc/trunk/tip/649.md)
+- [`Tcl_UtfToNormalized()`, `Tcl_UtfToNormalizedDString()` &mdash; C API for Unicode normalization](https://core.tcl-lang.org/tips/doc/trunk/tip/726.md)
+- [`Tcl_UtfToExternalEx()` and `Tcl_ExternalToUtfEx()` &mdash; C encoding API supporting output buffers larger than INT_MAX](https://core.tcl-lang.org/tips/doc/trunk/tip/737.md)
+- [New API for monotonic clock and microseconds resolution](https://core.tcl-lang.org/tips/doc/trunk/tip/723.md)
+- [Windows `auto_execok` enhancements and `exec` search reform](https://core.tcl-lang.org/tips/doc/trunk/tip/753.md)
+- [New timer API using long long in stead of Tcl_Time](https://core.tcl-lang.org/tips/doc/trunk/tip/752.md)
+
+# Changes in interpreter initialization
+
+- [Custom applications must call Tcl\_FindExecutable or TclZipfs_AppHook to initialize Tcl](https://core.tcl-lang.org/tips/doc/trunk/tip/732.md) *Potential incompatibility*
+- [Search path for locating Tcl core script and encodings is changed](https://core.tcl-lang.org/tips/doc/trunk/tip/732.md) *Potential incompatibility*
+- [`Tcl_RegisterPostInitProc` callback for post-initialization of interpreters](https://core.tcl-lang.org/tips/doc/trunk/tip/755.md)
+
+
+# Performance
+
+- [Memory efficient internal representations](https://core.tcl-lang.org/tcl/wiki?name=New+abstract+list+representations)
+for list operations on large lists.
+- [Continued 64-bit capacity: Command line arguments larger than 2Gb](https://core.tcl-lang.org/tips/doc/trunk/tip/626.md)
+- [Support for long paths on Windows](https://core.tcl-lang.org/tips/doc/trunk/tip/744.md)
+- [Faster UTF-8 encoding and I/O](https://core.tcl-lang.org/tcl/wiki?name=Faster+UTF+encoding)
+- Faster interpreter creation
+
+# Bug fixes
+- [Inconsistent `glob` matching on MacOS](https://core.tcl-lang.org/tcl/tktview/e6ca0b1b)
+- [`file normalize` does not uniquely identify a file on MacOS](https://core.tcl-lang.org/tcl/tktview/10890417)

- ****************************************************************************
- *
- *  Version 0.1.16.0
- *
- *  The ANSI C standard committee, for the C99 standard, specified the
- *  inclusion of a new standard include file called stdint.h.  This is
- *  a very useful and long desired include file which contains several
- *  very precise definitions for integer scalar types that is critically
- *  important for making several classes of applications portable
- *  including cryptography, hashing, variable length integer libraries
- *  and so on.  But for most developers its likely useful just for
- *  programming sanity.
- *
- *  The problem is that some compiler vendors chose to ignore the C99
- *  standard and some older compilers have no opportunity to be updated.
- *  Because of this situation, simply including stdint.h in your code
- *  makes it unportable.
- *
- *  So that's what this file is all about.  It's an attempt to build a
- *  single universal include file that works on as many platforms as
- *  possible to deliver what stdint.h is supposed to.  Even compilers
- *  that already come with stdint.h can use this file instead without
- *  any loss of functionality.  A few things that should be noted about
- *  this file:
- *
- *    1) It is not guaranteed to be portable and/or present an identical
- *       interface on all platforms.  The extreme variability of the
- *       ANSI C standard makes this an impossibility right from the
- *       very get go. Its really only meant to be useful for the vast
- *       majority of platforms that possess the capability of
- *       implementing usefully and precisely defined, standard sized
- *       integer scalars.  Systems which are not intrinsically 2s
- *       complement may produce invalid constants.
- *
- *    2) There is an unavoidable use of non-reserved symbols.
- *
- *    3) Other standard include files are invoked.
- *
- *    4) This file may come in conflict with future platforms that do
- *       include stdint.h.  The hope is that one or the other can be
- *       used with no real difference.
- *
- *    5) In the current version, if your platform can't represent
- *       int32_t, int16_t and int8_t, it just dumps out with a compiler
- *       error.
- *
- *    6) 64 bit integers may or may not be defined.  Test for their
- *       presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX.
- *       Note that this is different from the C99 specification which
- *       requires the existence of 64 bit support in the compiler.  If
- *       this is not defined for your platform, yet it is capable of
- *       dealing with 64 bits then it is because this file has not yet
- *       been extended to cover all of your system's capabilities.
- *
- *    7) (u)intptr_t may or may not be defined.  Test for its presence
- *       with the test: #ifdef PTRDIFF_MAX.  If this is not defined
- *       for your platform, then it is because this file has not yet
- *       been extended to cover all of your system's capabilities, not
- *       because its optional.
- *
- *    8) The following might not been defined even if your platform is
- *       capable of defining it:
- *
- *       WCHAR_MIN
- *       WCHAR_MAX
- *       (u)int64_t
- *       PTRDIFF_MIN
- *       PTRDIFF_MAX
- *       (u)intptr_t
- *
- *    9) The following have not been defined:
- *
- *       WINT_MIN
- *       WINT_MAX
- *
- *   10) The criteria for defining (u)int_least(*)_t isn't clear,
- *       except for systems which don't have a type that precisely
- *       defined 8, 16, or 32 bit types (which this include file does
- *       not support anyways). Default definitions have been given.
- *
- *   11) The criteria for defining (u)int_fast(*)_t isn't something I
- *       would trust to any particular compiler vendor or the ANSI C
- *       committee.  It is well known that "compatible systems" are
- *       commonly created that have very different performance
- *       characteristics from the systems they are compatible with,
- *       especially those whose vendors make both the compiler and the
- *       system.  Default definitions have been given, but its strongly
- *       recommended that users never use these definitions for any
- *       reason (they do *NOT* deliver any serious guarantee of
- *       improved performance -- not in this file, nor any vendor's
- *       stdint.h).
- *
- *   12) The following macros:
- *
- *       PRINTF_INTMAX_MODIFIER
- *       PRINTF_INT64_MODIFIER
- *       PRINTF_INT32_MODIFIER
- *       PRINTF_INT16_MODIFIER
- *       PRINTF_LEAST64_MODIFIER
- *       PRINTF_LEAST32_MODIFIER
- *       PRINTF_LEAST16_MODIFIER
- *       PRINTF_INTPTR_MODIFIER
- *
- *       are strings which have been defined as the modifiers required
- *       for the "d", "u" and "x" printf formats to correctly output
- *       (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t,
- *       (u)least32_t, (u)least16_t and (u)intptr_t types respectively.
- *       PRINTF_INTPTR_MODIFIER is not defined for some systems which
- *       provide their own stdint.h.  PRINTF_INT64_MODIFIER is not
- *       defined if INT64_MAX is not defined.  These are an extension
- *       beyond what C99 specifies must be in stdint.h.
- *
- *       In addition, the following macros are defined:
- *
- *       PRINTF_INTMAX_HEX_WIDTH
- *       PRINTF_INT64_HEX_WIDTH
- *       PRINTF_INT32_HEX_WIDTH
- *       PRINTF_INT16_HEX_WIDTH
- *       PRINTF_INT8_HEX_WIDTH
- *       PRINTF_INTMAX_DEC_WIDTH
- *       PRINTF_INT64_DEC_WIDTH
- *       PRINTF_INT32_DEC_WIDTH
- *       PRINTF_INT16_DEC_WIDTH
- *       PRINTF_UINT8_DEC_WIDTH
- *       PRINTF_UINTMAX_DEC_WIDTH
- *       PRINTF_UINT64_DEC_WIDTH
- *       PRINTF_UINT32_DEC_WIDTH
- *       PRINTF_UINT16_DEC_WIDTH
- *       PRINTF_UINT8_DEC_WIDTH
- *
- *       Which specifies the maximum number of characters required to
- *       print the number of that type in either hexadecimal or decimal.
- *       These are an extension beyond what C99 specifies must be in
- *       stdint.h.
- *
- *  Compilers tested (all with 0 warnings at their highest respective
- *  settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32
- *  bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio
- *  .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3
- *

+# For building with cmake at least version 3.12 (minizip 3.12) is needed
+
+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.
+
+## minizip-options with defaults ##
+
+    MINIZIP_BUILD_SHARED=ON -- Enable building minizip shared library
+
+    MINIZIP_BUILD_STATIC=ON -- Enable building minizip static library
+
+    MINIZIP_BUILD_TESTING=ON -- Enable testing of minizip
+
+    MINIZIP_ENABLE_BZIP2=ON -- Build minizip withj bzip2 support
+
+A usable installation of bzip2 is needed or config will fail. Turn this option of in this case.
+
+    MINIZIP_INSTALL=ON -- Enable installation of minizip
+
+This option is only available on mingw as they tend to name this lib different. Maybe this will also be
+removed in the future as. If you rely cmake for finding and using zlib, this can be turned off, as
+the other file 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
