+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.
