+Most of the core source files are in the **src/** subdirectory.  The
+**src/** folder also contains files used to build the "testfixture" test
+harness. The names of the source files used by "testfixture" all begin
+with "test".
+The **src/** also contains the "shell.c" file
+which is the main program for the "sqlite3.exe"
+[command-line shell](https://sqlite.org/cli.html) and
+the "tclsqlite.c" file which implements the
+[Tcl bindings](https://sqlite.org/tclsqlite.html) for SQLite.
+(Historical note:  SQLite began as a Tcl
+extension and only later escaped to the wild as an independent library.)

-## Source Tree Map
+Test scripts and programs are found in the **test/** subdirectory.
+Additional test code is found in other source repositories.
+See [How SQLite Is Tested](https://www.sqlite.org/testing.html) for
+additional information.

-  *  **src/** - This directory contains the primary source code for the
-     SQLite core.  For historical reasons, C-code used for testing is
-     also found here.  Source files intended for testing begin with "`test`".
-     The `tclsqlite3.c` and `tclsqlite3.h` files are the TCL interface
-     for SQLite and are also not part of the core.
+The **ext/** subdirectory contains code for extensions.  The
+Full-text search engine is in **ext/fts3**.  The R-Tree engine is in
+**ext/rtree**.  The **ext/misc** subdirectory contains a number of
+smaller, single-file extensions, such as a REGEXP operator.

-  *  **test/** - This directory and its subdirectories contains code used
-     for testing.  Files that end in "`.test`" are TCL scripts that run
-     tests using an augmented TCL interpreter named "testfixture".  Use
-     a command like "`make testfixture`" (unix) or 
-     "`nmake /f Makefile.msc testfixture.exe`" (windows) to build that
-     augmented TCL interpreter, then run individual tests using commands like
-     "`testfixture test/main.test`".  This test/ subdirectory also contains
-     additional C code modules and scripts for other kinds of testing.
-
-  *  **tool/** - This directory contains programs and scripts used to
-     build some of the machine-generated code that goes into the SQLite
-     core, as well as to build and run tests and perform diagnostics.
-     The source code to [the Lemon parser generator](./doc/lemon.html) is
-     found here.  There are also TCL scripts used to build and/or transform
-     source code files.  For example, the tool/mksqlite3h.tcl script reads
-     the src/sqlite.h.in file and uses it as a template to construct
-     the deliverable "sqlite3.h" file that defines the SQLite interface.
-
-  *  **ext/** - Various extensions to SQLite are found under this
-     directory.  For example, the FTS5 subsystem is in "ext/fts5/".
-     Some of these extensions (ex: FTS3/4, FTS5, RTREE) might get built
-     into the SQLite amalgamation, but not all of them.  The
-     "ext/misc/" subdirectory contains an assortment of one-file extensions,
-     many of which are omitted from the SQLite core, but which are included
-     in the [SQLite CLI](https://sqlite.org/cli.html).
-     
-  *  **doc/** - Some documentation files about SQLite internals are found
-     here.  Note, however, that the primary documentation designed for
-     application developers and users of SQLite is in a completely separate
-     repository.  Note also that the primary API documentation is derived
-     from specially constructed comments in the src/sqlite.h.in file.
+The **tool/** subdirectory contains various scripts and programs used
+for building generated source code files or for testing or for generating
+accessory programs such as "sqlite3_analyzer(.exe)".

-** pSavedRow:
-**   SQL statement FTS5_STMT_LOOKUP2 is a copy of FTS5_STMT_LOOKUP, it 
-**   does a by-rowid lookup to retrieve a single row from the %_content 
-**   table or equivalent external-content table/view.
-**
-**   However, FTS5_STMT_LOOKUP2 is only used when retrieving the original
-**   values for a row being UPDATEd. In that case, the SQL statement is
-**   not reset and pSavedRow is set to point at it. This is so that the
-**   insert operation that follows the delete may access the original 
-**   row values for any new values for which sqlite3_value_nochange() returns
-**   true. i.e. if the user executes:
-**
-**        CREATE VIRTUAL TABLE ft USING fts5(a, b, c, locale=1);
-**        ...
-**        UPDATE fts SET a=?, b=? WHERE rowid=?;
-**
-**   then the value passed to the xUpdate() method of this table as the 
-**   new.c value is an sqlite3_value_nochange() value. So in this case it
-**   must be read from the saved row stored in Fts5Storage.pSavedRow.
-**
-**   This is necessary - using sqlite3_value_nochange() instead of just having
-**   SQLite pass the original value back via xUpdate() - so as not to discard
-**   any locale information associated with such values.
