+This package contains:
+
+ * the SQLite library amalgamation source code file: sqlite3.c
+ * the sqlite3.h and sqlite3ext.h header files that define the C-language
+   interface to the sqlite3.c library file
+ * the shell.c file used to build the sqlite3 command-line shell program
+ * autoconf-like installation infrastucture for building on POSIX
+   compliant systems
+ * a Makefile.msc, sqlite3.rc, and Replace.cs for building with Microsoft
+   Visual C++ on Windows
+
+WHY USE THIS PACKAGE?
+=====================
+
+The canonical make system for SQLite requires TCL as part of the build
+process.  Various TCL scripts are used to generate parts of the code and
+TCL is used to run tests.  But some people would prefer to build SQLite
+using only generic tools and without having to install TCL.  The purpose
+of this package is to provide that capability.
+
+This package contains a pre-build SQLite amalgamation file "sqlite3.c"
+(and its associated header file "sqlite3.h").  Because the
+amalgamation has been pre-built, no TCL is required for the code
+generate (the configure script itself is written in TCL but it can use
+the embedded copy of JimTCL).
+
+REASONS TO USE THE CANONICAL BUILD SYSTEM RATHER THAN THIS PACKAGE
+==================================================================
+
+ * the canonical build system allows you to run tests to verify that
+   the build worked
+ * the canonical build system supports more compile-time options
+ * the canonical build system works for any arbitrary check-in to
+   the SQLite source tree
+
+Step-by-step instructions on how to build using the canonical make
+system for SQLite can be found at:
+
+  https://sqlite.org/src/doc/trunk/doc/compile-for-unix.md
+  https://sqlite.org/src/doc/trunk/doc/compile-for-windows.md
+
+
+SUMMARY OF HOW TO BUILD USING THIS PACKAGE
+==========================================
+
+  Unix:      ./configure; make
+  Windows:   nmake /f Makefile.msc
+
+BUILDING ON POSIX
+=================
+
+The configure script follows common conventions, making it easy
+to use for anyone who has configured a software tree before.
+It supports a number of build-time flags, the full list of which
+can be seen by running:
+
+  ./configure --help
+
+The default value for the CFLAGS variable (options passed to the C
+compiler) includes debugging symbols in the build, resulting in larger
+binaries than are necessary. Override it on the configure command
+line like this:
+
+  $ CFLAGS="-Os" ./configure
+
+to produce a smaller installation footprint.
+
+Many SQLite compilation parameters can be defined by passing flags
+to the configure script. Others may be passed on in the CFLAGS. For
+example:
+
+  $ CFLAGS="-Os -DSQLITE_OMIT_DEPRECATED" ./configure
+
+
+BUILDING WITH MICROSOFT VISUAL C++
+==================================
+
+To compile for Windows using Microsoft Visual C++:
+
+  $ nmake /f Makefile.msc
+
+Using Microsoft Visual C++ 2005 (or later) is recommended.  Several Windows
+platform variants may be built by adding additional macros to the NMAKE
+command line.
+
+
+Other preprocessor defines
+--------------------------
+
+Additionally, preprocessor defines may be specified by using the OPTS macro
+on the NMAKE command line.  However, not all possible preprocessor defines
+may be specified in this manner as some require the amalgamation to be built
+with them enabled (see http://sqlite.org/compile.html). For example, the
+following will work:
+
+  "OPTS=-DSQLITE_ENABLE_STAT4=1 -DSQLITE_OMIT_JSON=1"
+
+However, the following will not compile unless the amalgamation was built
+with it enabled:
+
+  "OPTS=-DSQLITE_ENABLE_UPDATE_DELETE_LIMIT=1"

+Maintaining Autosetup in the SQLite Tree
+========================================================================

+Autosetup API Reference
+========================================================================
+
+The Autosetup API is quite extensive and can be read either in
+the [files in the `autosetup` dir](/dir/autosetup) or using:
+
+>
+```
+$ ./configure --reference | less
+```
+
+That will include any docs from any TCL files in the `./autosetup` dir
+which contain certain (simple) markup defined by autosetup.
+
+This project's own configuration-related TCL code is spread across the
+following files:
+
+- [proj.tcl][]: project-agnostic utility code for autosetup-driven
+  projects. This file is designed to be shared between this project,
+  other projects managed under the SQLite/Hwaci umbrella
+  (e.g. Fossil), and personal projects of SQLite's developers.  It is
+  essentially an amalgamation of a decade's worth of autosetup-related
+  utility code.
+- [sqlite-config.tcl][]: utility code which is too project-specific
+  for `proj.tcl`. We split this out of `auto.def` so that it can be
+  used by both `auto.def` and...
+- [auto.def][]: the primary driver for the `./configure` process.
+  When we talk about "the configure script," we're technically
+  referring to this file, though it actually contains very little
+  of the TCL code.
+- [autoconf/auto.def][]: the main driver script for the "autoconf"
+  bundle's configure script. It is essentially a slightly trimmed-down
+  version of the main `auto.def` file. The `autoconf` dir was ported
+  from the Autotools to Autosetup in the 3.49.0 dev cycle but retains
+  the "autoconf" name to minimize downstream disruption.
+
+
+<a name="apitips"></a>
+Autosetup API Tips
+========================================================================
+
+This section briefly covers only APIs which are frequently useful in
+day-to-day maintenance and might not be immediately recognized as such
+from a casual perusal of the relevant TCL files. The complete docs of
+those with `proj-` prefix can be found in [proj.tcl][] and those with
+an `sqlite-` prefix are in [sqlite-config.tcl][]. The others are part
+of Autosetup's core packages and are scattered around [the TCL files
+in ./autosetup](/dir/autosetup).
+
+In (mostly) alphabetical order:
+
+- **`file-isexec filename`**\  
+  Should be used in place of `[file executable]`, as it will also
+  check for `${filename}.exe` on Windows platforms. However, on such
+  platforms it also assumes that _any_ existing file is executable.
+
+- **`get-env VAR ?default?`**\  
+  Will fetch an "environment variable" from the first of either: (1) a
+  KEY=VALUE passed to the configure script or (2) the system's
+  environment variables. Not to be confused with `getenv`, which only
+  does the latter and is rarely, if ever, useful in this tree.
+  - **`proj-get-env VAR ?default?`**\  
+    Works like `get-env` but will, if that function finds no match,
+    look for a file named `./.env-$VAR` and, if found, return its
+    trimmed contents. This can be used, e.g., to set a developer's
+    local preferences for the default `CFLAGS`.\  
+    Tip: adding `-O0` to `.env-CFLAGS` reduces rebuild times
+    considerably at the cost of performance in `make devtest` and the
+    like.
+
+- **`proj-fatal msg`**\  
+  Emits `$msg` to stderr and exits with non-zero. Its differences from
+  autosetup's `user-error` are purely cosmetic.
+
+- **`proj-if-opt-truthy flag thenScript ?elseScript?`**\  
+  Evals `thenScript` if the given `--flag` is truthy, else it
+  evals the optional `elseScript`.
+
+- **`proj-indented-notice ?-error? ?-notice? msg`**\  
+  Breaks its `msg` argument into lines, trims them, and emits them
+  with consistent indentation. Exactly how it emits depends on the
+  flags passed to it (or not), as covered in its docs. This will stick
+  out starkly from normal output and is intended to be used only for
+  important notices.
+
+- **`proj-opt-truthy flag`**\  
+  Returns 1 if `--flag`'s value is "truthy," i.e. one of (1, on,
+  enabled, yes, true).
+
+- **`proj-opt-was-provided FLAG`**\  
+  Returns 1 if `--FLAG` was explicitly provided to configure,
+  else 0. This distinction can be used to determine, e.g., whether
+  `--with-readline` was provided or whether we're searching for
+  readline by default. In the former case, failure to find it should
+  be treated as fatal, where in the latter case it's not.\  
+  Unlike most functions which deal with `--flags`, this one does not
+  validate that `$FLAG` is a registered flag so will not fail fatally
+  if `$FLAG` is not registered as an Autosetup option.
+
+- **`proj-val-truthy value`**\  
+  Returns 1 if `$value` is "truthy," See `proj-opt-truthy` for the definition
+  of "truthy."
+
+- **`proj-warn msg`**\  
+  Emits `$msg` to stderr. Closely-related is autosetup's `user-notice`
+  (described below).
+
+- **`sqlite-add-feature-flag ?-shell? FLAG...`**\  
+  Adds the given feature flag to the CFLAGS which are specific to
+  building libsqlite3. It's intended to be passed one or more
+  `-DSQLITE_ENABLE_...`, or similar, flags. If the `-shell` flag is
+  used then it also passes its arguments to
+  `sqlite-add-shell-opt`. This is a no-op if `FLAG` is not provided or
+  is empty.
+
+- **`sqlite-add-shell-opt FLAG...`**\  
+  The shell-specific counterpart of `sqlite-add-feature-flag` which
+  only adds the given flag(s) to the CLI-shell-specific CFLAGS.
+
+- **`sqlite-configure BUILD-NAME {script}`**\  
+  This is where all configure `--flags` are defined for all known
+  build modes ("canonical" or "autoconf"). After processing all flags,
+  this function runs `$script`, which contains the build-mode-specific
+  configuration bits, and then runs any finalization bits which are
+  common to all build modes. The `auto.def` files are intended to contain
+  exactly two commands:
+  `use sqlite-config; sqlite-configure BUILD-NAME {script}`
+
+- **`user-notice msg`**\  
+  Queues `$msg` to be sent to stderr, but does not emit it until
+  either `show-notices` is called or the next time autosetup would
+  output something (it internally calls `show-notices`). This can be
+  used to generate warnings between a "checking for..." message and
+  its resulting "yes/no/whatever" message in such a way as to not
+  spoil the layout of such messages.
+
+
+<a name="tclcompat"></a>
+Ensuring TCL Compatibility
+========================================================================
+
+One of the significant benefits of using Autosetup is that (A) this
+project uses many TCL scripts in the build process and (B) Autosetup
+comes with a TCL interpreter named [JimTCL][].
+
+It is important that any TCL files used by the configure process and
+makefiles remain compatible with both [JimTCL][] and the canonical
+TCL. Though JimTCL has outstanding compatibility with canonical TCL,
+it does have a few corners with incompatibilities, e.g. regular
+expressions. If a script runs in JimTCL without using any
+JimTCL-specific features, then it's a certainty that it will run in
+canonical TCL as well. The opposite, however, is not _always_ the
+case.
+
+When [`./configure`](/file/configure) is run, it goes through a
+bootstrapping process to find a suitable TCL with which to run the
+autosetup framework. The first step involves [finding or building a
+TCL shell](/file/autosetup/autosetup-find-tclsh).  That will first
+search for an available `tclsh` (under several common names,
+e.g. `tclsh8.6`) before falling back to compiling the copy of
+`jimsh0.c` included in the source tree. i.e. it will prefer to use a
+system-installed TCL for running the configure script. Once it finds
+(or builds) a TCL shell, it then runs [a sanity test to ensure that
+the shell is suitable](/file/autosetup/autosetup-test-tclsh) before
+using it to run the main autosetup app.
+
+There are two simple ways to ensure that running of the configure
+process uses JimTCL instead of the canonical `tclsh`, and either
+approach provides equally high assurances about configure script
+compatibility across TCL implementations:
+
+1. Build on a system with no `tclsh` installed in the `$PATH`. In that
+   case, the configure process will fall back to building the in-tree
+   copy of JimTCL.
+
+2. Manually build `./jimsh0` in the top of the checkout with:\  
+   `cc -o jimsh0 autosetup/jimsh0.c`\  
+   With that in place, the configure script will prefer to use that
+   before looking for a system-level `tclsh`. Be aware, though, that
+   `make distclean` will remove that file.
+
+**Note that `./jimsh0` is distinctly different from the `./jimsh`**
+which gets built for code-generation purposes.  The latter requires
+non-default build flags to enable features which are
+platform-dependent, most notably to make its `[file normalize]` work.
+This means, for example, that the configure script and its utility
+APIs must not use `[file normalize]`, but autosetup provides a
+TCL-only implementation of `[file-normalize]` (note the dash) for
+portable use in the configure script. Contrariwise, code-generation
+scripts invoked via `make` may use `[file normalize]`, as they'll use
+`./jimsh` or `tclsh` instead of `./jimsh0`.
+
+
+Known TCL Incompatibilities
+------------------------------------------------------------------------
+
+A summary of known incompatibilities in JimTCL
+
+- **CRNL line endings**: prior to 2025-02-05 `fconfigure -translation ...`
+  was a no-op in JimTCL, and it emits CRNL line endings by default on
+  Windows.  Since then, it supports `-translation binary`, which is
+  close enough to `-translation lf` for our purposes. When working
+  with files using the `open` command, it is important to use mode
+  `"rb"` or `"wb"`, as appropriate, so that the output does not get
+  CRNL-mangled on Windows.
+
+- **`file copy`** does not support multiple source files. See
+  [](/info/61f18c96183867fe) for a workaround.
+
+- **Regular expressions**:
+
+  - Patterns treat `\nnn` octal values as back-references (which it
+    does not support). Those can be reformulated as demonstrated in
+    [](/info/aeac23359bb681c0).
+
+  - `regsub` does not support the `\y` flag. A workaround is demonstrated
+    in [](/info/c2e5dd791cce3ec4).
+
+
+<a name="conventions"></a>
+Design Conventions
+========================================================================
+
+This section describes the motivations for the most glaring of the
+build's design decisions, in particular how they deviate from
+historical, or even widely-conventional, practices.
+
+Symbolic Names of Feature Flags
+------------------------------------------------------------------------
+
+Historically, the project's makefile has exclusively used
+`UPPER_UNDERSCORE` form for makefile variables. This build, however,
+primarily uses `X.y` format, where `X` is often a category label,
+e.g. `CFLAGS`, and `y` is the specific instance of that category,
+e.g. `CFLAGS.readline`.
+
+When the configure script exports flags for consumption by filtered
+files, e.g. [Makefile.in][] and the generated
+`sqlite_cfg.h`, it does so in the more conventional `X_Y` form because
+those flags get exported as as C `#define`s to `sqlite_cfg.h`, where
+dots are not permitted.
+
+The `X.y` convention is used in the makefiles primarily because the
+person who did the initial port finds that considerably easier on the
+eyes and fingers. In practice, the `X_Y` form of such exports is used
+exactly once in [Makefile.in][], where it's translated from `@X_Y@`
+into into `X.y` form for consumption by [Makefile.in][] and
+[main.mk][]. For example:
+
+>
+```
+LDFLAGS.shobj = @SHOBJ_LDFLAGS@
+LDFLAGS.zlib = @LDFLAGS_ZLIB@
+LDFLAGS.math = @LDFLAGS_MATH@
+```
+
+(That first one is defined by autosetup, and thus applies "LDFLAGS" as
+the suffix rather than the prefix. Which is more legible is a matter
+of taste, for which there is no accounting.)
+
+
+Do Not Update Global Shared State
+------------------------------------------------------------------------
+
+In both the legacy Autotools-driven build and common Autosetup usage,
+feature tests performed by the configure script may amend global flags
+such as `LIBS`, `LDFLAGS`, and `CFLAGS`[^as-cflags].  That's
+appropriate for a makefile which builds a single deliverable, but less
+so for makefiles which produce multiple deliverables. Drawbacks of
+that approach include:
+
+- It's unlikely that every single deliverable will require the same
+  core set of those flags.
+- It can be difficult to determine the origin of any given change to
+  that global state because those changes are hidden behind voodoo
+  performed outside the immediate visibility of the configure script's
+  maintainer.
+- It can force the maintainers of the configure script to place tests
+  in a specific order so that the resulting flags get applied at
+  the correct time and/or in the correct order.\  
+  (A real-life example: before the approach described below was taken
+  to collecting build-time flags, the test for `-rpath` had to come
+  _after_ the test for zlib because the results of the `-rpath` test
+  implicitly modified global state which broke the zlib feature
+  test. Because the feature tests no longer (intentionally) modify
+  shared global state, that is not an issue.)
+
+In this build, cases where feature tests modify global state in such a
+way that it may impact later feature tests are either (A) very
+intentionally defined to do so (e.g. the `--with-wasi-sdk` flag has
+invasive side-effects) or (B) are oversights (i.e. bugs).
+
+This tree's [configure script][auto.def], [utility APIs][proj.tcl],
+[Makefile.in][], and [main.mk][] therefore strive to separate the
+results of any given feature test into its own well-defined
+variables. For example:
+
+- The linker flags for zlib are exported from the configure script as
+  `LDFLAGS_ZLIB`, which [Makefile.in][] and [main.mk][] then expose as
+  `LDFLAGS.zlib`.
+- `CFLAGS_READLINE` (a.k.a. `CFLAGS.readline`) contains the `CFLAGS`
+  needed for including `libreadline`, `libedit`, or `linenoise`, and
+  `LDFLAGS_READLINE` (a.k.a. `LDFLAGS.readline`) is its link-time
+  counterpart.
+
+It is then up to the Makefile to apply and order the flags however is
+appropriate.
+
+At the end of the configure script, the global `CFLAGS` _ideally_
+holds only flags which are either relevant to all targets or, failing
+that, will have no unintended side-effects on any targets. That said:
+clients frequently pass custom `CFLAGS` to `./configure` or `make` to
+set library-level feature toggles, e.g. `-DSQLITE_OMIT_FOO`, in which
+case there is no practical way to avoid "polluting" the builds of
+arbitrary makefile targets with those. _C'est la vie._
+
+
+[^as-cflags]: But see this article for a detailed discussion of how
+    autosetup currently deals specifically with CFLAGS:
+    <https://msteveb.github.io/autosetup/articles/handling-cflags/>
+
+
+<a name="updating"></a>
+Updating Autosetup
+========================================================================
+
+Updating autosetup is, more often than not, painless. It requires having
+a checked-out copy of [the autosetup git repository][autosetup-git]:
+
+>
+```
+$ git clone https://github.com/msteveb/autosetup
+$ cd autosetup
+# Or, if it's already checked out:
+$ git pull
+```
+
+Then, from the top-most directory of an SQLite checkout:
+
+>
+```
+$ /path/to/autosetup-checkout/autosetup --install .
+$ fossil status # show the modified files
+```
+
+Unless the upgrade made any incompatible changes (which is exceedingly
+rare), that's all there is to it.  After that's done, **apply a patch
+for the change described in the following section**, test the
+configure process, and check it in.
+
+<a name="patching"></a>
+Patching Autosetup for Project-local Changes
+------------------------------------------------------------------------
+
+Autosetup reserves the flag name **`--debug`** for its own purposes,
+and its own special handling of `--enable-...` flags makes `--debug`
+an alias for `--enable-debug`. As this project has a long history of
+using `--enable-debug`, we patch autosetup to use the name
+`--autosetup-debug` in place of `--debug`. That requires (as of this
+writing) four small edits in
+[/autosetup/autosetup](/file/autosetup/autosetup), as demonstrated in
+[check-in 3296c8d3](/info/3296c8d3).
+
+If autosetup is upgraded and this patch is _not_ applied the invoking
+`./configure` will fail loudly because of the declaration of the
+`debug` flag in `auto.def` - duplicated flags are not permitted.
+
+<a name="branch-customization"></a>
+Branch-specific Customization
+========================================================================
+
+Certain vendor-specific branches require slight configure script
+customization. Rather than editing `sqlite-config.tcl` for this,
+which frequently leads to merge conflicts, the following approach
+is recommended:
+
+In the vendor-specific branch, create a file named
+`autosetup/sqlite-custom.tcl`.
+
+That file should contain the following content...
+
+If flag customization is required, add:
+
+>
+```
+proc sqlite-custom-flags {} {
+  # If any existing --flags require different default values
+  # then call:
+  options-defaults {
+    flag-name new-default-value
+    ...
+  }
+  # ^^^ That will replace the default value but will not update
+  # the --help text, which may lead to some confusion:
+  # https://github.com/msteveb/autosetup/issues/77
+
+  return {
+   {*} {
+     new-flag-name => {Help text}
+     ...
+   }
+  }; #see below
+}
+```
+
+That function must return either an empty string or a list in the form

+.SH NAME
+.B sqlite3 
+\- A command line interface for SQLite version 3
+
+.SH SYNOPSIS
+.B sqlite3
+.RI [ options ]
+.RI [ databasefile ]
+.RI [ SQL ]
+
+.SH SUMMARY
+.PP
+.B sqlite3
+is a terminal-based front-end to the SQLite library that can evaluate
+queries interactively and display the results in multiple formats.
+.B sqlite3
+can also be used within shell scripts and other applications to provide
+batch processing features.
+
+.SH DESCRIPTION
+To start a
+.B sqlite3
+interactive session, invoke the
+.B sqlite3
+command and optionally provide the name of a database file.  If the
+database file does not exist, it will be created.  If the database file
+does exist, it will be opened.
+
+For example, to create a new database file named "mydata.db", create
+a table named "memos" and insert a couple of records into that table:
+.sp
+$ 
+.B sqlite3 mydata.db
+.br
+SQLite version 3.43.0 2023-08-11 17:45:23
+.br
+Enter ".help" for usage hints.
+.br
+sqlite>
+.B create table memos(text, priority INTEGER);
+.br
+sqlite>
+.B insert into memos values('deliver project description', 10);
+.br
+sqlite>
+.B insert into memos values('lunch with Christine', 100);
+.br
+sqlite>
+.B select * from memos;
+.br
+deliver project description|10
+.br
+lunch with Christine|100
+.br
+sqlite>
+.sp
+
+If no database name is supplied, the ATTACH sql command can be used
+to attach to existing or create new database files.  ATTACH can also
+be used to attach to multiple databases within the same interactive
+session.  This is useful for migrating data between databases,
+possibly changing the schema along the way.
+
+Optionally, a SQL statement or set of SQL statements can be supplied as
+a single argument.  Multiple statements should be separated by
+semi-colons.
+
+For example:
+.sp
+$ 
+.B sqlite3 -line mydata.db 'select * from memos where priority > 20;'
+.br
+    text = lunch with Christine
+.br
+priority = 100
+.br
+.sp
+
+.SS SQLITE META-COMMANDS
+.PP
+The interactive interpreter offers a set of meta-commands that can be
+used to control the output format, examine the currently attached
+database files, or perform administrative operations upon the
+attached databases (such as rebuilding indices).   Meta-commands are
+always prefixed with a dot (.).
+
+A list of available meta-commands can be viewed at any time by issuing
+the '.help' command.  For example:
+.sp
+sqlite>
+.B .help
+.nf
+.tr %.
+...
+.sp
+.fi
+
+The available commands differ by version and build options, so they
+are not listed here. Please refer to your local copy for all available
+options.
+
+
+.SH INIT FILE
+.B sqlite3
+reads an initialization file to set the configuration of the
+interactive environment.  Throughout initialization, any previously
+specified setting can be overridden.  The sequence of initialization is
+as follows:
+
+o The default configuration is established as follows:
+
+.sp
+.nf
+.cc |
+mode            = LIST
+separator       = "|"
+main prompt     = "sqlite> "
+continue prompt = "   ...> "
+|cc .
+.sp
+.fi
+
+o If the environment variable XDG_CONFIG_HOME is set then
+.B ${XDG_CONFIG_HOME}/sqlite3/sqliterc
+is checked, else
+.B ~/.config/sqlite3/sqliterc
+is checked. If the selected file does not exist then the fallback of
+.B ~/.sqliterc
+is used. It should generally only contain meta-commands.
+
+o If the -init option is present, the specified file is processed.
+
+o All other command line options are processed.
+
+.SH HISTORY FILE
+.B sqlite3
+may be configured to use a history file to save SQL statements and
+meta-commands entered interactively. These statements and commands can be
+retrieved, edited and, reused at the main and continue prompts. If the
+environment variable
+.B SQLITE_HISTORY
+is set, it will be used as the name of the history file, whether it
+already exists or not. If it is not set but the XDG_STATE_HOME
+environment variable is then
+.B ${XDG_STATE_HOME}/sqlite_history
+is used. If XDG_STATE_HOME is not set then
+.B ~/.local/state/sqlite_history
+is used. If the selected file does not exist then
+.B ~/.sqlite_history
+will be used as the history file. If any history file is found, it
+will be written if the shell exits interactive mode normally,
+regardless of whether it existed previously, though saving will
+silently fail if the history file's directory does not exist.

+This is the SQLite extension for Tcl using something akin to
+the Tcl Extension Architecture (TEA). To build it:
+
+    ./configure ...flags...
+
+e.g.:
+
+    ./configure --with-tcl=/path/to/tcl/install/root
+
+or:
+
+    ./configure --with-tclsh=/path/to/tcl/install/root
+
+Run ./configure --help for the full list of flags.
+
+The configuration process will fail if tclConfig.sh cannot be found.
+
+The makefile will only honor CFLAGS and CPPFLAGS passed to the
+configure script, not those directly passed to the makefile.
+
+Then:
+
+    make test install
+
+----------------------- THE PREFERRED WAY ---------------------------
+
+The preferred way to build the TCL extension for SQLite is to use the
+canonical source code tarball.  For Unix:
+
+    ./configure --with-tclsh=$(TCLSH)
+    make tclextension-install
+
+For Windows:
+
+    nmake /f Makefile.msc tclextension-install TCLSH_CMD=$(TCLSH)
+
+In both of the above, replace $(TCLSH) with the full pathname of
+of the tclsh that you want the SQLite extension to work with.  See
+step-by-step instructions at the links below for more information:
+
+    https://sqlite.org/src/doc/trunk/doc/compile-for-unix.md
+    https://sqlite.org/src/doc/trunk/doc/compile-for-windows.md
+
+And info about the extension's Tcl interface can be found at:
+
+    https://sqlite.org/tclsqlite.html
+
+The whole point of the amalgamation-autoconf tarball (in which this
+README.txt file is embedded) is to provide a means of compiling SQLite
+that does not require first installing TCL and/or "tclsh".  The
+canonical Makefile in the SQLite source tree provides more
+capabilities (such as the the ability to run test cases to ensure that
+the build worked) and is better maintained.  The only downside of the
+canonical Makefile is that it requires a TCL installation.  But if you
+are wanting to build the TCL extension for SQLite, then presumably you
+already have a TCL installation.  So why not just use the more-capable
+and better-maintained canoncal Makefile?
+
+As of version 3.50.0, this build process uses "teaish":
+
+    https://fossil.wanderinghorse.net/r/teaish
+
+which is conceptually derived from the pre-3.50 toolchain, TEA:
+
+    http://core.tcl-lang.org/tclconfig
+    http://core.tcl-lang.org/sampleextension
+
+It to works for us.  It might also work for you.  But we cannot
+promise that.
+
+If you want to use this TEA builder and it works for you, that's fine.
+But if you have trouble, the first thing you should do is go back
+to using the canonical Makefile in the SQLite source tree.
+
+------------------------------------------------------------------
+
+
+UNIX BUILD
+==========
+
+Building under most UNIX systems is easy, just run the configure
+script and then run make. For example:
+
+	$ cd sqlite-*-tea
+	$ ./configure --with-tcl=/path/to/tcl/install/root
+	$ make test
+	$ make install
+
+WINDOWS BUILD
+=============
+
+On Windows this build is known to work on Cygwin and some Msys2
+environments. We do not currently support Microsoft makefiles for
+native Windows builds.
