since it will be shared with WebCore and Gears in the
future.

+This directory contains a partial snapshot of the sqlite library from
+http://sqlite.org.
+
+Current version: 3.5.3, released 23-Nov-2007.
+
+(This was built as 3.4.2 [13-Aug-2007] as described below, with the four
+intervening patches 4315, 4427, 4546, and 4556 applied by hand.)
+
+To import a new snapshot of sqlite:
+
+- Visit http://sqlite.org/download.html and download the latest source
+  distribution.
+- Unpack the source on a Linux machine.
+- Change to the source directory and run:
+    $ ./configure --disable-tcl  # build headers
+    $ make                       # build some generated files
+- Copy the generated .c/.h files from the sqlite directory to this directory,
+  as well as those in src/ and ext/fts2/.  Omit files which have been omitted
+  here.  Here's an easy way to be sure you get everything:
+    $ cp /path/to/source/*.[ch] .  # don't forget subdirs, too
+    $ gvn status | grep -v ^M      # print the names of all new files
+    $ mkdir new; mv each new file to new
+    Then rebuild, and if any of the files in new/ are needed, move them
+    back into this directory, add them to the project, and "gvn add" them.
+- Apply the preload-cache.diff (see below)
+- Update this README to reflect the new version number.
+
+Modifications for this release:
+- I marked all changes I made with "evanm", so you can find them with
+  "grep evanm *".
+- Most files include sqlite3ext.h with SQLITE_CORE #defined, but two don't:
+  fts2_tokenizer.c and icu.c.  Without this #define, the calls in
+  fts2_tokenizer.c try to go through some pointer to the sqlite API instead of
+  calling the functions directly (to work as a loadable module), but then crash
+  (because the other files never initialize that loadable module support).  As
+  a hack I #defined it in these files, but it'd be nice to figure out what
+  really ought to happen here (perhaps this file is new and hasn't been tested
+  to verify it works right).
+- shell_icu.c is a Chrome-specific file used to load our ICU data.  shell.c
+  has been modifed to call into shell_icu.c.
+- fts2_icu.c has a critical bug. U8_NEXT is used over a UTF-16 string. It's replaced
+  by U16_NEXT (jungshik)
+
+Patch
+-----
+The file preload-cache.diff patch must be applied to add a new function we use
+to prime the database cache. It allows much faster performance by reading the
+file in one contiguous operation rather than bringing it in organically, which
+involves a lot of seeking.
+
+FTS2 modification
+-----------------
+In fts2.c, we added an additional check from fts3 to try to catch some
+additional problems. In buildTerms on line 3807, we replaced
+    if( iPosition<0 ){
+with:
+    if( iPosition<0 || pToken == NULL || nTokenBytes == 0 ){
+It is from this change to sqlite:
